Grimdark Future: Battlefields (Fan Content)

2025-08-11T17:33:23Z

EMD: /* Special Rules */ Added Focus Fire

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

If a Shaken unit fails a morale test that would cause it to be Shaken that unit retreats and is removed from play.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks with those weapons against the building first. When determining hits, all hits from Blast wound on a 2+. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Focus Fire ===
When using Hold actions, this weapon shoots at 12".

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size

|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2
|4"
|3+
|3+

|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm

|Claws (A5)
|190
|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

If a Shaken unit fails a morale test that would cause it to be Shaken that unit retreats and is removed from play.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks with those weapons against the building first. When determining hits, all hits from Blast wound on a 2+. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.

Grimdark Future: Battlefields (Fan Content)

2025-08-07T21:21:28Z

EMD: /* Army Books, Unit Proxies, and Steam Workshop Links */ Added Core Rules page link.

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

If a Shaken unit fails a morale test that would cause it to be Shaken that unit retreats and is removed from play.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks with those weapons against the building first. When determining hits, all hits from Blast wound on a 2+. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value.

EMD: /* Shaken Units */

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

If a Shaken unit fails a morale test that would cause it to be Shaken that unit retreats and is removed from play.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks with those weapons against the building first. When determining hits, all hits from Blast wound on a 2+. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks with those weapons against the building first. When determining hits, all hits from Blast wound on a 2+. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon

|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2
|4"

|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm

|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon

|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"

|Claws (A5)
|190
|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

EMD: /* Army Books, Unit Proxies, and Steam Workshop Links */

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.

* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport.

For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, as they are primarily designed as a booster for other units in your army, and not using Combined Units unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"

The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”

EMD: /* Preparing your Army */

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army, and not using Combined Unit unless playing a scenario.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size

!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2
|4"
|3+
|3+
|6
|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm

|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.

To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Linked ===
Unmodified rolls of 6 to hit deal one extra hit (only the original hit counts as a 6 for special rules).

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”
* 18” to 24” = 8”(9”)
* 30” to 36” = 12”
* 36” to 48” = 18”
* 48” to 72” = 24”
* 72” to 120” = 30”
* 120”+ = 36”

=== Example Units ===

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.

A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.

EMD: /* Unit Design Principles */ Example Weapon Ranges

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can easily be added to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Weapon Ranges ===

* 6” to 12” = 6”

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.) and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===

[[File:Camphoto 824023566.jpg|thumb|Example 2D gameplay between Battle Brothers and Alive Hive on poker chips with foam sheet terrain. ]]

GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===

|-

|4"

|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.

A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.

Grimdark Future: Battlefields (Fan Content)

2025-05-14T17:40:08Z

EMD:

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Field Works ===
This unit may only be shot at by an enemy weapon with Blast (6+). If this unit ever fails a morale test it is removed from play.

In addition, this unit may not be activated and is not counted towards determining which player runs out of activations first at the end of each round.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size

!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2

|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"

|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

Grimdark Future: Battlefields (Fan Content)

2025-05-13T21:48:20Z

EMD: /* Army Books, Unit Proxies, and Steam Workshop Links */

A fan made OPR modification by EMD for playing games in the Grimdark Future in 6-10mm scale.

With some core rule and scale changes, Grimdark Future: Battlefields (GDF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by massive war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Protective Field ===
When taking a wound, roll one die. On a 5+ it is ignored. If this unit has both Regeneration and Protective Field, they must pick which rule they will use for each wound taken.

''Designer Note: While using the same rule wording as Regeneration, Protective Fields are not subject to the same special rules. This includes not being improved by rules like Regen-Booster, but also means it is not ignored by rules like Poison.''

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapons
!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"
|+Battle Brother Squad
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapons

!Cost
|-
|2
|4"
|3+
|3+
|6
|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapons
!Melee Weapons
!Cost
|-

|3
|
|Claws (A5)
|190
|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"
|+Orc Rocket Mob

A specialized unit of Orcs that are hoping for a lucky hit, but when they hit boy does it hit hard.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.

* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 heroes per 750 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units and Magic Items.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay.

* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Towers and buildings.

Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 heroes per 750 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Age of Fantasy.

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Towers and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+Human Empire Infantrymen w/ Spears & Shields

!Ranged Weapons
!Melee Weapons
!Cost
|-
|4
|4"
|4+

|3

|Spears (A3, Counter)
|130
|}
While each units has a large number of bases, and models per base, the Infantrymen don't have a great survival rate, or will retreat from battlefield if too many soldiers from their group are killed; hence the low tough value. There is however an entire section worth of spears pointed down range, so they make a great unit for holding objectives.

Heavy infantry unit from a more elite army, the Saurian Gators are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of melee; so an increase in Tough and number of melee weapon attacks.

EMD: /* Preparing your Army */

A fan made OPR modification by EMD for playing games in the Age of Fantasy in 6-10mm scale.

With some core rule and scale changes, Age of Fantasy: Battlefields (AoF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 heroes per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Age of Fantasy.

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Towers and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"

!Ranged Weapons
!Melee Weapons

|-
|4

|Spears (A3, Counter)
|130
|}
While each units has a large number of bases, and models per base, the Infantrymen don't have a great survival rate, or will retreat from battlefield if too many soldiers from their group are killed; hence the low tough value. There is however an entire section worth of spears pointed down range, so they make a great unit for holding objectives.

Heavy infantry unit from a more elite army, the Saurian Gators are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of melee; so an increase in Tough and number of melee weapon attacks.

EMD: /* Game Structure and Movement */

A fan made OPR modification by EMD for playing games in the Age of Fantasy in 6-10mm scale.

With some core rule and scale changes, Age of Fantasy: Battlefields (AoF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

|}

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===

=== Force Organization ===

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport.

For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==
Rules in this section are added to or replace their special rules counter parts in Grimdark Future.

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size

!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"
|+Battle Brother Squad
!Size

!Quality
!Defense

|-
|2
|4"
|3+
|3+
|6
|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm

|Claws (A5)
|190
|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

A specialized unit of Orcs that are hoping for a lucky hit, but when they hit boy does it hit hard.

EMD: /* Special Rules */

A fan made OPR modification by EMD for playing games in the Age of Fantasy in 6-10mm scale.

With some core rule and scale changes, Age of Fantasy: Battlefields (AoF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 heroes per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast

EMD: /* Preparing your Army */

A fan made OPR modification by EMD for playing games in the Age of Fantasy in 6-10mm scale.

With some core rule and scale changes, Age of Fantasy: Battlefields (AoF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 heroes per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"

|-

|}
While each units has a large number of bases, and models per base, the Infantrymen don't have a great survival rate, or will retreat from battlefield if too many soldiers from their group are killed; hence the low tough value. There is however an entire section worth of spears pointed down range, so they make a great unit for holding objectives.

Heavy infantry unit from a more elite army, the Saurian Gators are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of melee; so an increase in Tough and number of melee weapon attacks.
{| class="wikitable"

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Hero Units ===

If the unit would take a large number of hits that are likely to remove it from play, players should roll a number of defense dice equal to the unit’s remaining tough at a time.

=== Hero ===
Models with the Hero special rule not attached to a unit may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

Heroes may join, detach, and deploy with multi-model units without another Hero. While attached to that unit, it activates with the Hero as a single unit. The hero may take morale tests on behalf of the unit they are currently attached to, but must use that unit’s Defense until all other models have been killed.

At the beginning of its activation a Hero may detach from a unit by moving out of coherency with it. This move may be used to attached to a different unit, but that unit may not activate for the remainder of the round. The unit the Hero detached from this round may activate as normal as long as it didn’t move or perform any action then the Hero detached.

Note that when a Hero joins a unit, they count as part of that unit, so the unit’s size is increased by 1, and even if the hero is the last model remaining, it takes morale tests as the unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Hero Units ===
When a unit with an attached Hero takes hits from shooting, it must assign those hits to the unit until the Hero is the only remaining model. If the unit would take a large number of hits that are likely to remove it from play, players should roll a number of defense dice equal to the unit’s remaining tough at a time. If all models in the unit are removed as a casualty, any remaining hits will be redirected to the Hero.

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule not attached to a unit may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

Heroes may join, detach, and deploy with multi-model units without another Hero. While attached to that unit, it activates with the Hero as a single unit. The hero may take morale tests on behalf of the unit they are currently attached to, but must use that unit’s Defense until all other models have been killed.

At the beginning of its activation a Hero may detach from a unit by moving out of coherency with it. This move may be used to attached to a different unit, but that unit may not activate for the remainder of the round. The unit the Hero detached from this round may activate as normal as long as it didn’t move or perform any action then the Hero detached.

Note that when a Hero joins a unit, they count as part of that unit, so the unit’s size is increased by 1, and even if the hero is the last model remaining, it takes morale tests as the unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+Human Empire Infantrymen w/ Spears & Shields
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapons
!Melee Weapons
!Cost
|-
|4
|4"
|4+
|6+
|3
|
|Spears (A3, Counter)
|130
|}
While each units has a large number of bases, and models per base, the Infantrymen don't have a great survival rate, or will retreat from battlefield if too many soldiers from their group are killed; hence the low tough value. There is however an entire section worth of spears pointed down range, so they make a great unit for holding objectives.
{| class="wikitable"
|+Saurian Gators
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapons
!Melee Weapons
!Cost
|-
|2
|4"
|4+
|5+
|6
|
|Great Weapons (A6, AP(2)), Thick Claws & Teeth (A2, AP(1))
|220
|}
Heavy infantry unit from a more elite army, the Saurian Gators are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of melee; so an increase in Tough and number of melee weapon attacks.
{| class="wikitable"
|+Vampiric Undead Bat Swarms
!Size
!Movement
!Quality

|}
A mass of flying bats moving quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds and block line of sight of ranged attack.
{| class="wikitable"

As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Hero Units ===
When a unit with an attached Hero takes hits from shooting, it must assign those hits to the unit until the Hero is the only remaining model. If the unit would take a large number of hits that are likely to remove it from play, players should roll a number of defense dice equal to the unit’s remaining tough at a time. If all models in the unit are removed as a casualty, any remaining hits will be redirected to the Hero.

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule not attached to a unit may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

Heroes may join, detach, and deploy with multi-model units without another Hero. While attached to that unit, it activates with the Hero as a single unit. The hero may take morale tests on behalf of the unit they are currently attached to, but must use that unit’s Defense until all other models have been killed.

At the beginning of its activation a Hero may detach from a unit by moving out of coherency with it. This move may be used to attached to a different unit, but that unit may not activate for the remainder of the round. The unit the Hero detached from this round may activate as normal as long as it didn’t move or perform any action then the Hero detached.

Note that when a Hero joins a unit, they count as part of that unit, so the unit’s size is increased by 1, and even if the hero is the last model remaining, it takes morale tests as the unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"

|-
|2

The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

Age of Fantasy: Battlefields (Fan Content)

2025-05-02T21:20:10Z

EMD: Creating Age of Fantasy: Battlefields page with copied GDF:BF to start.

A fan made OPR modification by EMD for playing games in the Age of Fantasy in 6-10mm scale.

With some core rule and scale changes, Age of Fantasy: Battlefields (AoF:BF) allows for small scale games with small scale models, all the way up to massive scale games where the battlefield is dominated by war machines and monsters.

If you have any questions, or difficulty getting started, feel free to ping EMD on the OPR Discord.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
AoF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a horde of Zombies with 10 models on a single base, or an elite unit like Knights will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in AoF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing AoF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 1500 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Hero is attached to an infantry unit, it must stay within coherency to that unit while it is attached.

== Shooting & Melee ==

=== Hero Units ===
When a unit with an attached Hero takes hits from shooting, it must assign those hits to the unit until the Hero is the only remaining model. If the unit would take a large number of hits that are likely to remove it from play, players should roll a number of defense dice equal to the unit’s remaining tough at a time. If all models in the unit are removed as a casualty, any remaining hits will be redirected to the Hero.

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's transport and one of those hits causes a wound, all future hits must be assigned to that transport until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores Cover, and after resolving other special rules, each hit is multiplied by X.

=== Deadly ===
Ignores Protected, and after resolving other special rules each wound is multiplied by X. Hits from Deadly must be resolved first, and these wounds don’t carry over to other models if the original target is killed.

=== Hero ===
Models with the Hero special rule not attached to a unit may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

Heroes may join, detach, and deploy with multi-model units without another Hero. While attached to that unit, it activates with the Hero as a single unit. The hero may take morale tests on behalf of the unit they are currently attached to, but must use that unit’s Defense until all other models have been killed.

At the beginning of its activation a Hero may detach from a unit by moving out of coherency with it. This move may be used to attached to a different unit, but that unit may not activate for the remainder of the round. The unit the Hero detached from this round may activate as normal as long as it didn’t move or perform any action then the Hero detached.

Note that when a Hero joins a unit, they count as part of that unit, so the unit’s size is increased by 1, and even if the hero is the last model remaining, it takes morale tests as the unit.

=== Magic Item ===
This unit must be attached to any model with the Hero or Sergeant special rule during deployment. Add any upgraded attacks or bonuses of this Magic Item to the attached model. Only one upgrade may chosen per Magic Item (the multiple sections are there for easy reading). This unit doesn’t count towards Force Organization for Max 1 unit per full 150pts, but does for Max Unit Copies. While this unit has a stat line, it does not need to have a model represented on the table. If the unit this item is attached to is removed from play, the Magic Item is removed as well.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Skirmishers ===
Enemies get -1 to hit rolls when shooting at units where all models have this rule from over 8" away. In addition, allied models may move through this unit when charging.

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to AoF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that the transport with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in AoF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|4
|4"
|4+
|4+
|3
|Bows (8", A3)
|CCWs (A3)
|100pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for AoF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and groups of monsters.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5+: Hoards and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for AoF:BF.
* 6": Standard monster and fast infantry movement speed.
* 8": Really fast units only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Teleporting units.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles and monsters, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Armored Wagon: Defense 3+, Tough(3), Protected
** Monster Transport: Defense 3+, Tough(3), Fast
** Large Monster: Defense 3+, Tough(6), Protected
** Massive Monster: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Large monsters.
* 12: Massive monsters.
* 15+: Titanic monsters. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"

!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2
|4"
|3+
|3+
|6
|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.

EMD: Added Age of Fantasy section and Age of Fantasy: Battlefields page

This page lists all of the current fan content and modules that players have created around the OPR game systems. Below are links to those modules.

== All OPR Games ==

=== Construction & Conquest ===
Addon for both Grimdark Future and Age of Fantasy, changing into a fully fledged turn-based strategy, with a lot of extended features:

* base building, with many different types of buildings, including defense installations,
* resource mining and management from battlefield field deposits,
* army recruitment,
* technology unlocks,
* superweapons.

Designed to be fully compatible with all balanced armies available on Army Forge, both official, community and 3rd party ones, while fitting on one page.

Gameflow is inspired by Red Alert series, and playtested quite heavily locally in each version before global release. Discord handles of the authors: bartholomeus_betula & Crassvs from OPR Poland community (feel free to contact us with any feedback!).

Latest version (currently v1.3) available [https://drive.google.com/drive/folders/1XebDmPXvUg-uSOH9Yy2zUiixwR1FvqpO HERE] in English and Polish as one paged PDFs for both Grimdark Future and Age of Fantasy.

=== Diceless OPR (DOPR) ===
Minor Mod made to convert OPR games to rely less on the randomness of dice rolling and focus more on the strategy aspect of the game. The creator of this module is Jamis Buck.

The latest version (v0.2) can be found [https://jamisbuck.org/files/diceless_opr_v0.2.pdf here] (PDF document).

== Grimdark Future ==

=== Grimdark Future: Horde Mode ===
Currently in a beta phase of gameplay, it is an unofficial modification of Poorhammer’s Horde Mode v0.83, designed to work with Grimdark Future from OnePageRules. The creator of this module is RelicLord in the OPR discord.

The latest google document can be found [https://docs.google.com/document/d/1TINEYJBDObEmmbH_2gu9oZgo4zjNMmqoPk2w-_hPGZU/edit here]. There is an accompanying Table Top Simulator table created by Custodes in the discord that can be found [https://steamcommunity.com/sharedfiles/filedetails/?id=3167621908 here.]

=== Apocalyptic Games - Formations ===
This set of rules is meant to complement the OPR system, accounting for truly gigantic armies. It is compatible with the Advanced Rulebooks of GF and AoF. It is suitable for games of 4000pts and above and meant to reduce the number of activations by using groups of units instead of individual ones. It can also be combined with any optional rule set, including Apocalyptic Games. The creator of this module is ''.nedland'' on discord.

The latest google document can be found [https://drive.google.com/file/d/1kFZQJOumyW-v04SfSjS7d0IL7Z4mIjq3/view here].

=== TinyGF ===
A modification to the Grimdark Future rules designed for epic battles with 6mm to 15mm models. Rules are on the Tiny Battles of the Great Crusade Facebook page or here [https://drive.google.com/drive/folders/1WvxcBD5kiCHPG_NGTYJOqecjaHy3ymau] . Armylists are all found on the Army Forge under the Community lists and begin with "TinyGF." Note that army composition is described in the details of each army - without that information the entries won't make sense.

=== Grimdark Future: Advanced Factions ===
A lightweight set of rules for Grimdark Future to allow for flavorful additions of narrative faction rules, as well as a dynamic way to incorporate certain rulesets from the Advanced Rulebook.

The google document can be found [https://docs.google.com/document/d/18HnrWqa5GPdGrgm-q_8sN_KcfGeg-A5REQMQDXTtccg/edit?usp=drive_link here].

=== Grimdark Future: Dawn of War ===
This is an unofficial game mod created for Grimdark Future inspired by Dawn of War real time strategy game. The creator of this mod is Mr.LittleSword in the OPR discord. Creators e-mail: lex.lib45@gmail.com

The latest google document can be found [https://drive.google.com/drive/folders/14Duc4xxsDbRZNIgJHOepmUjEjoleF-Ry?usp=drive_link here].

Mode strvey can be found [https://docs.google.com/forms/d/e/1FAIpQLSfPCsWZ1uXp77O-GXL7NIlagt_j5_slXHzcgoErZX1Ehojqmw/viewform?usp=sf_link here].

=== [[Grimdark Future: Battlefields (Fan Content)|Grimdark Future: Battlefields]] ===
A 6-10mm OPR modification by EMD that allows for small and large scale battles where each model represents an entire squad of infantry, up to massive creations of war. A key change to the OPR formula for GDF:BF is the use of Base-4 instead of 6, meaning the majority of infantry move 4", weapons like rifles shoot 8", with large weapons like artillery stretching out to 36".

Rules and armies lists can be found on the Army Forge Community Books tab, as well as unit proxy army builders in the Steam Workshop for Table Top Simulator, by searching for GDF:BF.

Feel free to ping EMD on the OPR Discord if you have any questions.

[https://steamcommunity.com/sharedfiles/filedetails/?id=3223613213 Steam Workshop for GDF:Battlefields introduction game.]

=== Mech Warfare ===
In the near future, humanity has traveled among the stars, colonized thousands of new worlds, and the wars of these new systems are dominated by massive walking war machines. Mech Warfare is an OPR ruleset modification designed for 6-8mm miniatures. Models should be based on 30mm hex bases, or 25-32mm round bases.

Because of the scale difference and core rule changes, this modification and army book are not designed to work with other Grimdark Future army books.

Feel free to ping EMD on the OPR Discord if you have any questions.

[https://drive.google.com/drive/u/1/folders/198B69Pn0SQYrEjg0_cXlmQPSSkM1nnIJ Google Drive link to current Mech Warfare documents.]

=== Grimdark Future - Competitive Redesigns ===
A list of redesigns for armies that need help in competitive play. The goal is to make all armies relatively equal in power level to Alien Hives.

== Age of Fantasy ==

=== [[Age of Fantasy: Battlefields (Fan Content)|Age of Fantasy: Battlefields]] ===
A 6-10mm OPR modification by EMD that allows for small and large scale battles where each model represents an entire squad of infantry, up to massive magical creatures and creations of war. A key change to the OPR formula for AoF:BF is the use of Base-4 instead of 6, meaning the majority of infantry move 4", weapons like bows shoot 8", with massive weapons like field artillery stretching out to 36".

Rules and armies lists can be found on the Army Forge Community Books tab, as well as unit proxy army builders in the Steam Workshop for Table Top Simulator, by searching for AoF:BF.

Feel free to ping EMD on the OPR Discord if you have any questions.

== Age of Fantasy: Regiments ==

=== Age of Fantasy: Battle Masters ===
Battle Masters is a 10mm fantasy strategy game that is a total conversion project for the OPR system. Using inspiration from older 10mm fantasy games, players will activate heroes within their army, and use those hero's orders to controller their forces. Combat is simultaneous and fast paced, without book keeping mechanics like wound tracking.

Models should be mounted on rectangular based, and the Google Drive link below contains print out for playing 2D armies on dominos. Because this is a total conversion, this modification and army books are not designed to work with other Age of Fantasy army books.

Feel free to ping EMD on the OPR Discord if you have any questions.

An alternate game mode designed for 10mm miniatures and all the things that usually accompanies, AoFR:Warlords is made by Liver Ripamonti (''ripripla'' on discord)and maintained as a community book through army forge studio. It is very modular, allowing to customize any unit to fit almost any miniature or army, and since it functions with only one book, balance changes can be easily done.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 6-10mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===
{| class="wikitable"
|+HDF Infantry Platoon
!Size
!Movement
!Quality
!Defense

!Ranged Weapons
!Melee Weapons
!Cost
|-
|5
|4"
|4+
|5+
|3
|Rifles (8", A3)
|CCWs (A3)
|165
|}
While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.
{| class="wikitable"

|-
|2
|4"
|3+
|3+
|6
|Heavy Rifles (8", A4, AP(1))
|Heavy CCWs (A3, AP(1))
|225
|}
The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.
{| class="wikitable"
|+Assault Grunt Swarm

|}
A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
{| class="wikitable"

A specialized unit of Orcs that are hoping for a lucky hit, but when they hit boy does it hit hard.

EMD: /* Grimdark Future: Battlefields */

This page lists all of the current fan content and modules that players have created around the OPR game systems. Below are links to those modules.

== All OPR Games ==

=== Construction & Conquest ===
Addon for both Grimdark Future and Age of Fantasy, changing into a fully fledged turn-based strategy, with a lot of extended features:

* base building, with many different types of buildings, including defense installations,
* resource mining and management from battlefield field deposits,
* army recruitment,
* technology unlocks,
* superweapons.

Designed to be fully compatible with all balanced armies available on Army Forge, both official, community and 3rd party ones, while fitting on one page.

Gameflow is inspired by Red Alert series, and playtested quite heavily locally in each version before global release. Discord handles of the authors: bartholomeus_betula & Crassvs from OPR Poland community (feel free to contact us with any feedback!).

Latest version (currently v1.3) available [https://drive.google.com/drive/folders/1XebDmPXvUg-uSOH9Yy2zUiixwR1FvqpO HERE] in English and Polish as one paged PDFs for both Grimdark Future and Age of Fantasy.

=== Diceless OPR (DOPR) ===
Minor Mod made to convert OPR games to rely less on the randomness of dice rolling and focus more on the strategy aspect of the game. The creator of this module is Jamis Buck.

The latest version (v0.2) can be found [https://jamisbuck.org/files/diceless_opr_v0.2.pdf here] (PDF document).

== Grimdark Future ==

=== Grimdark Future: Horde Mode ===
Currently in a beta phase of gameplay, it is an unofficial modification of Poorhammer’s Horde Mode v0.83, designed to work with Grimdark Future from OnePageRules. The creator of this module is RelicLord in the OPR discord.

The latest google document can be found [https://docs.google.com/document/d/1TINEYJBDObEmmbH_2gu9oZgo4zjNMmqoPk2w-_hPGZU/edit here]. There is an accompanying Table Top Simulator table created by Custodes in the discord that can be found [https://steamcommunity.com/sharedfiles/filedetails/?id=3167621908 here.]

=== Apocalyptic Games - Formations ===
This set of rules is meant to complement the OPR system, accounting for truly gigantic armies. It is compatible with the Advanced Rulebooks of GF and AoF. It is suitable for games of 4000pts and above and meant to reduce the number of activations by using groups of units instead of individual ones. It can also be combined with any optional rule set, including Apocalyptic Games. The creator of this module is ''.nedland'' on discord.

The latest google document can be found [https://drive.google.com/file/d/1kFZQJOumyW-v04SfSjS7d0IL7Z4mIjq3/view here].

=== TinyGF ===
A modification to the Grimdark Future rules designed for epic battles with 6mm to 15mm models. Rules are on the Tiny Battles of the Great Crusade Facebook page or here [https://drive.google.com/drive/folders/1WvxcBD5kiCHPG_NGTYJOqecjaHy3ymau] . Armylists are all found on the Army Forge under the Community lists and begin with "TinyGF."

=== [[Grimdark Future: Battlefields (Fan Content)|Grimdark Future: Battlefields]] ===
A 6-10mm OPR modification by EMD that allows for small and large scale battles where each model represents an entire squad of infantry, up to massive creations of war. A key change to the OPR formula for GDF:BF is the use of Base-4 instead of 6, meaning the majority of infantry move 4", weapons like rifles shoot 8", with large weapons like artillery stretching out to 36".

Rules and armies lists can be found on the Army Forge Community Books tab, as well as unit proxy army builders in the Steam Workshop for Table Top Simulator, by searching for GDF:BF.

Feel free to ping EMD on the OPR Discord if you have any questions.

=== Mech Warfare ===
In the near future, humanity has traveled among the stars, colonized thousands of new worlds, and the wars of these new systems are dominated by massive walking war machines. Mech Warfare is an OPR ruleset modification designed for 6-8mm miniatures. Models should be based on 30mm hex bases, or 25-32mm round bases.

Because of the scale difference and core rule changes, this modification and army book are not designed to work with other Grimdark Future army books.

=== Soldiers of Fortune ===
Solo or coop ruleset that allows players to control a Company of Mercenaries and take on procedurally generated Contracts to fight the powers at be.

Available for free on [https://ward-against-evil.itch.io/soldiers-of-fortune Itch.io]

== Age of Fantasy: Regiments ==

=== Age of Fantasy: Battle Masters ===
Battle Masters is a 10mm fantasy strategy game that is a total conversion project for the OPR system. Using inspiration from older 10mm fantasy games, players will activate heroes within their army, and use those hero's orders to controller their forces. Combat is simultaneous and fast paced, without book keeping mechanics like wound tracking.

Models should be mounted on rectangular based, and the Google Drive link below contains print out for playing 2D armies on dominos. Because this is a total conversion, this modification and army books are not designed to work with other Age of Fantasy army books.

Feel free to ping EMD on the OPR Discord if you have any questions.

It is very modular, allowing to customize any unit to fit almost any miniature or army, and since it functions with only one book, balance changes can be easily done.

EMD: /* Age of Fantasy: Skirmish/Grimdark Future: Firefight */ Page cleanup and broken links section added

This page lists all of the current fan content and modules that players have created around the OPR game systems. Below are links to those modules.

== All OPR Games ==

=== Construction & Conquest ===
Addon for both Grimdark Future and Age of Fantasy, changing into a fully fledged turn-based strategy, with a lot of extended features:

* base building, with many different types of buildings, including defense installations,
* resource mining and management from battlefield field deposits,
* army recruitment,
* technology unlocks,
* superweapons.

Designed to be fully compatible with all balanced armies available on Army Forge, both official, community and 3rd party ones, while fitting on one page.

Gameflow is inspired by Red Alert series, and playtested quite heavily locally in each version before global release. Discord handles of the authors: bartholomeus_betula & Crassvs from OPR Poland community (feel free to contact us with any feedback!).

Latest version (currently v1.3) available [https://drive.google.com/drive/folders/1XebDmPXvUg-uSOH9Yy2zUiixwR1FvqpO HERE] in English and Polish as one paged PDFs for both Grimdark Future and Age of Fantasy.

=== Diceless OPR (DOPR) ===
Minor Mod made to convert OPR games to rely less on the randomness of dice rolling and focus more on the strategy aspect of the game. The creator of this module is Jamis Buck.

The latest version (v0.2) can be found [https://jamisbuck.org/files/diceless_opr_v0.2.pdf here] (PDF document).

== Grimdark Future ==

=== Grimdark Future: Horde Mode ===
Currently in a beta phase of gameplay, it is an unofficial modification of Poorhammer’s Horde Mode v0.83, designed to work with Grimdark Future from OnePageRules. The creator of this module is RelicLord in the OPR discord.

The latest google document can be found [https://docs.google.com/document/d/1TINEYJBDObEmmbH_2gu9oZgo4zjNMmqoPk2w-_hPGZU/edit here]. There is an accompanying Table Top Simulator table created by Custodes in the discord that can be found [https://steamcommunity.com/sharedfiles/filedetails/?id=3167621908 here.]

=== Apocalyptic Games - Formations ===
This set of rules is meant to complement the OPR system, accounting for truly gigantic armies. It is compatible with the Advanced Rulebooks of GF and AoF. It is suitable for games of 4000pts and above and meant to reduce the number of activations by using groups of units instead of individual ones. It can also be combined with any optional rule set, including Apocalyptic Games. The creator of this module is ''.nedland'' on discord.

The latest google document can be found [https://drive.google.com/file/d/1kFZQJOumyW-v04SfSjS7d0IL7Z4mIjq3/view here].

=== TinyGF ===
A modification to the Grimdark Future rules designed for epic battles with 6mm to 15mm models. Rules are on the Tiny Battles of the Great Crusade Facebook page or here [https://drive.google.com/drive/folders/1WvxcBD5kiCHPG_NGTYJOqecjaHy3ymau] . Armylists are all found on the Army Forge under the Community lists and begin with "TinyGF." Note that army composition is described in the details of each army - without that information the entries won't make sense.

=== Grimdark Future: Advanced Factions ===
A lightweight set of rules for Grimdark Future to allow for flavorful additions of narrative faction rules, as well as a dynamic way to incorporate certain rulesets from the Advanced Rulebook.

== General Principles ==
While the core principles of the OPR system still apply, there are a few key and rule changes that will be listed below.

=== Scale Conversion ===
GDF:BF uses 8mm miniatures that are mounted on round bases of various sizes representative to the unit's presence on the battlefield. Each base may have multiple miniatures mounted on it, like a swarm of Alien Hive with 10 models on a single base, or an elite force like Battle Brothers will be represented with 5 infantry models per base.

* '''Infantry:''' 40mm round bases.
* '''Large Infantry:''' 40 or 50mm round bases.
* '''Bikes:''' 40 or 50mm round bases.
* '''Monsters and Walkers:''' 40mm round bases.
* '''Vehicles:''' 40mm or 50mm round bases.
* '''War Machines:''' 40, 50, 60mm or bigger round bases.

If making a 2D printable version, all models can be represented by 39/40mm rounds (poker chips) for ease of purchasing and transportation.

=== Measuring Distances ===
To help game feel with the smaller scale, it uses a Base-4 system. This means that the standard unit movement in the game is 4", instead of 6". In Army Forge, this is achieved by the majority of units being given the Slow special rule.

'''Important:''' If a rule or weapon contains 9" as a measurement, read it as 8".

''For example, in GDF:BF, Ambush is 8" away from the nearest enemy.''

=== Line of Sight ===
Designer recommends only using Top-Down Line of Sight (aka 2D LoS) for determining line of sight when playing GDF:BF, making sure all terrain has easily identifiable edges so there is limited confusion if a model is or is not in cover.

== Preparation ==

=== Preparing the Battlefield ===
As a part of converting to Base-4, the standard table size is reduced to 48"x32", with no-man's land being 16". For larger games where each player is bringing war machines and monsters, or is looking for more movement based strategies, a 6'x4' surface would be appropriate.

=== The Mission ===
Standard games are still based on a length of 4 rounds, but for games on larger tables with massive armies the round limit should be extended to 6.

=== Preparing your Army ===
Designer recommends only having 1 hero per 2000 pts, but this is more around how they are primarily designed as a booster for other units in your army.

=== Force Organization ===
For building out units in Army Forge, ignore the unit count and copy limit for transport units that have been attached to infantry units.

=== Deploying Armies ===
The standard deployment zone for players is 8" from their table edge.

== Game Structure and Movement ==

=== Unit Coherency ===
All models in a unit must stay within base contact, or as close as possible, to at least one other model in its unit.

If a Transport Unit is attached to an infantry unit, it must stay within coherency to that unit.

== Shooting & Melee ==

=== Transport Unit and Wound Allocation ===
When a unit with an attached Transport Unit takes hits, it must chose to assign those hits to the unit or the transport. As with standard rules, when a Tough unit takes a wound, it must be assigned all hits until it is removed from play. For example: If the player decided to assign hits to their unit's Light APC and one of those hits causes a wound, all future hits must be assigned to that Light APC until it is removed from play.

If a large number of hits would be assigned to a model that are likely to remove it from play, players should roll a number of defense dice equal to the models remaining tough at a time. If the model is removed as a casualty, any remaining hits will be redirected to a different model in the unit.

== Melee Resolution & Morale ==

=== Morale & When to Test ===
A unit losing 50% or more of its current tough value in a single activation, or losing a melee, must take a moral test.

''For example: An Orc Hoard with 3 models remaining at the beginning of the turn (tough value of 18) suffers 10 wounds from enemy shooting. Because the unit lost 50% or more of its remaining tough value from the start of the turn they must take a moral test at the end of the current turn.''

=== Shaken Units ===
Shaken units count as being Fatigued, suffer a -1 penalty to all dice rolls (melee, shooting, defense, morale, etc.), and may not contest or hold any objective. A Shaken unit may remove their Shaken status by remaining idle and doing nothing during their activation.

== Terrain ==

=== Cover Terrain ===
Defense rolls automatically succeed on a roll of 5 or 6.

=== Intact Buildings (Optional) ===
Units in an Intact Building gain +1 to Defense rolls and the Protected special rule.

If attacking a unit in an Intact Building with a Blast(6+) or Deadly(9+) weapon, roll your attacks against the building first. When determining hits, gain all hits from Blast regardless of the building's size. Buildings have Defense 3+ and the Protected special rule. If the building would suffer 6 wounds in a single attack, it is destroyed. Roll as many dice as the remaining tough value for any units that were in the building, and for each result of 1-3 the unit takes one wound, which can't be ignored.

Replace any destroyed intact buildings with ruins of appropriate size. This new terrain piece has the Cover, Difficult, and Dangerous Terrain rules.

== Special Rules ==

=== Blast ===
Ignores cover, and after resolving other special rule, each hit is multiplied by X.

=== Hero ===
Models with the Hero special rule may not be targeted by any attack or charge unless they are the closest model to the attacking unit.

=== Protected ===
When this unit takes hits, those hits count as having AP(-1), to a min. of AP(0).

=== Transport Unit ===
This model and its unit move +2" on Advance, and +4" on Rush/Charge.

''Designer Note: This is the unique mechanic to GDF:BF; units do not sit within their transport, removed from the board until they exit, instead all units remain in play throughout the duration of gameplay. The rule should be read as 'the unit this model is attached to moves at the same rate and with the same special rules as the transport unit'. For Army Forge, many transports have the Slow special rule, this is so that a unit like that Light APC with no unit attached will move at 6", instead of 8". In all the Steam Workshops, the movement stat is/should be written as the final movement speed for the model.''

=== Transport: X ===
Attach an X to this unit. (Purchase an X and deploy it with this unit)

''Designer Note: For Army Force, these unit upgrades cost 0 as the cost comes from adding the unit to your army list. When attached, the transport may not leave the unit, and as stated above ignore the Force Organization warnings for multiple copies of transports added to your list if they are purchased for the unit upgrade.''

=== Tunneller ===
This model counts as having Ambush, and may be deployed up to 1" away from enemy units. However, this model may not be deployed in such a way that an enemy hero is the closest enemy unit to it.

== Unit Design Principles ==

=== Standard Unit ===
The standard unit in GDF:BF has the following stat line:
{| class="wikitable"
!Size
!Movement
!Quality
!Defense
!Tough
!Ranged Weapon
!Melee Weapon
!Cost
|-
|2
|4"
|4+
|4+
|3
|Rifles (8", A3)
|CCWs (A3)
|50pts
|}
The unit represents a squad of 8-12 infantry, split between two bases to make up the unit. As with other OPR systems, there is a soft recommendation for unit creation based on their equipment, and for GDF:BF, what is the theme of the unit on a larger scale battle.

=== Unit Size ===

* 1: For powerful hero units, larger vehicles, war machines, and massive monsters.
* 2: Squads of infantry that have a transport upgrade options, elite infantry units, and sections of vehicles.
* 3: Specialty units that focus on one thing like rapid movement, heavy weaponry, or melee combat.
* 4: Larger infantry units that don't have transport options, but aren't themed around being a hoard.
* 5: Hoards, platoons, and swarms of bodies. These units have a lot of weight behind them but normally find themselves running on foot across the board.

=== Movement Speed ===

* Immobile: Turrets and buildings.
* 4": The standard movement rate for GDF:BF.
* 6": Standard vehicle and fast infantry movement speed.
* 8": Really fast vehicles only. Not recommended for melee focused units as we'd like to avoid first activation charges.
* 10": Very, very fast units. Aerospace fighters and transports.

=== Quality and Defense ===

* Same for standard OPR.
* For vehicles, Defense 2+ should be reserved for very powerful or thick armors heroes, monsters, and vehicles only. The vast majority of vehicles should also have the Protected special rule.
** Light APC: Defense 3+, Tough(3), Protected
** Skimmer Transport: Defense 3+, Tough(3), Fast
** Battle Tank: Defense 3+, Tough(6), Protected
** Heavy Tank: Defense 2+, Tough(9), Protected

=== Tough ===

* 3: The standard tough value; only narrative things should have less.
* 6: More durable units and monsters.
* 9: Heavy vehicles.
* 12: Super heavy vehicles.
* 15+: Titans and War Machines. Things you don't bother shooting at unless it's with Deadly(6+) weaponry.

=== Weapon Attacks ===

* 1: Barely an effect, or there as an additive as an attached unit.
** For example: Light APC with a Storm Rifle (8", A1, AP(1)) so it can add to the Battle Squad's Heavy Rifles (8", A4, AP(1))
* 2: Weak ranges or melee attacks, or low model count within the unit.
* 3: Standard for ranged and melee combat.
* 4; Skilled fighters for that weapon system.
* 5: Specialist for that weapon or large model count within the unit.
* 6+: Specialized weapons or elite level unit.

=== Example Units ===

While each units has a large number of bases, and models per base, the HDF Infantry don't have a great survival rate, or will retreat from battlefield if too many soldiers from their squad are killed; hence the low tough value. There is however an entire platoons worth of rifles pointed down range, so volume of fire they can dish out if very high.

The standard infantry unit from a more elite army, the Battle Brothers are more durable and better armored than the standard infantry unit, and despite low numbers they are more deadly with their application of firepower; so an increase in Tough and number of ranged weapon attacks.

A mass of deadly bodies running quickly across the battlefield. Individuals aren't nearly as dangerous as the swarm, which will just absorb wounds until they inevitably get within a claws reach; so a fast speed, a hoards worth of wounds, and a specialized units for close range enemy removal.
