| Core Mechanic | Roll d100 equal to or under your skill percentage. Success tiers at half (Hard) and one-fifth (Extreme) of the skill value. Bonus and penalty dice adjust the tens digit. Failed rolls can be pushed for a second attempt at greater risk. | 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 For | Investigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots. | 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. |
| Highlights | Tracking Sanity as a depletable score ties mental erosion to the fiction, so confronting cosmic horror mechanically wears characters down. The percentile skills resolve on a d100 roll-under, with Hard and Extreme bands at half and one-fifth of the rating. Bouts of Madness convert failed Sanity checks into temporary phobias, manias, or loss of character control. | 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 |
| Considerations | The chase rules add a detailed positioning subsystem whose complexity outweighs how often it sees use. Character creation allocates points across a long list of skills, a slow first step for new players. In long campaigns the sanity spiral can strip a character of player control as madness accumulates. | 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 |
