Core MechanicAttacks roll d20 against an attack matrix or an optional ascending Armour Class target. Saving throws meet a category target on d20. Ability checks roll at or below an ability score on d20.Roll one attribute die and one skill die, each rated as a step die (d6, d8, d10, or d12). A result of 6+ on either die is a success; 10+ counts as two successes. Rolls can be pushed for extra dice at the cost of damage or stress. Ammo dice track ammunition expenditure during firefights, degrading with use.

Best ForGroups who want treasure-driven dungeon expeditions and open wilderness campaigns with fragile starting characters.Groups who want a gritty military survival sandbox where managing ammunition, fuel, food, and shelter matters as much as combat, set against a Cold War-gone-hot alternate history.
HighlightsTreasure recovered from adventures provides most experience points, rewarding successful exploration over fighting alone. Reaction and optional morale rolls let encounters lead to negotiation or flight instead of automatic combat. Stronghold construction and taxation let accumulated wealth support a growing domain.Hex-based travel and exploration system with structured daily tasks (march, forage, scrounge, rest), detailed but playable firearms and vehicle rules with real-world military equipment, ammo dice mechanic abstracts ammunition management without individual round tracking, base-building rules for establishing and upgrading a home settlement
ConsiderationsCharacters die at zero hit points, and failed poison saves are usually fatal. Demihuman characters combine ancestry with class and have lower level limits than human classes. Declared spells are lost if the caster is hit or fails a saving throw before acting.Combat lethality can frustrate players attached to their characters, large core set with multiple booklets and maps to manage, narrow post-apocalyptic military premise limits campaign variety, step dice mechanic produces a flat probability curve with high variance on individual rolls
