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.
HighlightsTracking 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.Player-facing d20 rolls keep resolution minimal. The Calendar of Nechrubel ticks the world toward a scripted apocalypse during play. Scroll-based powers can misfire, making magic a gamble.
ConsiderationsThe 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.Class balance varies significantly, core book layout prioritizes style over reference usability, random character generation limits player investment
