Core MechanicRoll 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 d20 + modifier against a Difficulty Class. Heroes are built from a Power Points budget capped by a series Power Level (usually 10), which limits paired trait totals — attack bonus + effect rank, dodge + toughness — to twice the level. Damage is resisted with Toughness checks that escalate conditions (bruised, staggered, incapacitated) instead of tracking hit points. Hero Points let players reroll, edit scenes, or recover from conditions; complications coming into play earn them back.

Best ForInvestigation-driven horror where combat is deadly and sanity is fragile. Great for one-shots.Groups who want unlimited freedom to design any superhero concept — from masked vigilante to cosmic powerhouse — with a flexible point-buy build system and tactical combat that emphasizes power-level balance.
HighlightsSanity system mechanically reinforces horror tone. Intuitive percentile skill system with tiered success levels. One of the largest published scenario libraries in the hobby.Modular power-construction system builds any superpower from effects, modifiers, and flaws; Power Level caps enforce balance even when individual traits vary widely; Hero Points reward roleplaying complications with mechanical benefits; conditions track damage progression instead of using a hit point pool
ConsiderationsChase rules add complexity with limited payoff, 46-skill list requires point allocation across multiple categories, sanity spiral can remove player agency in extended campaignsCharacter creation requires significant rules mastery to navigate the point-buy power construction; resolving an attack involves multiple checks per action — attack roll, Toughness resistance, condition tracking; Power Level caps can frustrate players who want to push paired-trait limits like attack and effect rank
