Best ForInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.Short, brutal sessions in an apocalyptic setting where characters are disposable, the rules are minimal, and lethality is the point.
HighlightsSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.Ultra-light rules, distinctive art direction, large third-party scene
ConsiderationsChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaignsClass balance varies significantly, core book layout prioritizes style over reference usability, random character generation limits player investment
