Core MechanicCombat and saving throws use a d20 plus bonuses, with high results overcoming a target number or opposing roll. Skills use d100 and succeed when the result is at or below the character's percentage.Players roll a pool of 1–3 d6s against a target difficulty (4 for easy, 5 for average, 6 for hard). Every challenge starts with 1 die: add a second if the challenge matches the character's stat (Agile, Brawny, or Crafty), and a third if their role applies (The Veteran, Rookie, Medic, Gizmo, Detective, or Weirdo). Success means at least one die meets or beats the difficulty. Players spend luck tokens to invoke a perk and lower the difficulty by 1, and recover luck by letting their quirk cause a problem (raising the difficulty by 1). Grit tokens absorb failure consequences; a character who runs out of grit is removed from the scene. The referee never rolls dice during a challenge: they choose the stat and difficulty, then narrate the outcome. Extended challenges (chases, fights, infiltration) deplete a shared pool of effort tokens, one per success.

Best ForGroups who want long-form science-fantasy campaigns that move from a ruined Earth to other dimensions. The game suits tables whose GM will decide which parts of the broad setting a campaign uses.Groups who want a quick, comedic cosmic-horror RPG that pairs Baywatch-style melodrama with the Cthulhu Mythos. Tuned for pickup play and 2-4 hour sessions, with three tonal modes (Casual, Standard, Horror) that retune lethality without changing the core rules.
HighlightsOccupational and racial class packages assign distinct abilities and advancement tracks, giving each archetype a different role in the party. Mega-Damage places many supernatural creatures and war machines on a separate durability scale beyond the reach of ordinary Structural Damage Capacity attacks. Rifts and ley lines make dimensional travel a standing feature of the setting, letting campaigns move between devastated Earth and other worlds.Three difficulty targets and a 1–3 d6 dice pool make up the entire resolution system. Three tonal modes (Casual, Standard, Horror) adjust grit recovery rate, retuning the same rules from sitcom-style play to deadly survival horror without changing any mechanics. All heroes share a universal Slow Motion quirk: narrating a slow-motion moment recovers a luck token but raises the current challenge's difficulty. Adventure generator combines random Objective, Location, and Complication tables for pickup scenarios; also includes an Elder Gods & Cults table, a Monster Maker, and a mapped Sunset Hills setting.
ConsiderationsCharacter creation combines rolled attributes with extensive skill selection, making first-time preparation lengthy. Combat asks each player to track an action economy, active defenses, and which damage scale applies. Magic and psionics use separate point pools and power procedures, adding class-specific rules to the shared system.Mechanically minimal: no advancement track beyond optional luck and grit cap increases, no gear lists, no tactical combat structure. Pacing assumes 2–4 hour sessions rather than multi-arc campaigns. Setting is anchored to Sunset Hills, California; running the game elsewhere requires reskinning the included cult, NPC, and location tables. Three difficulty values and a maximum 3-die pool give coarse resolution: granular skill differentiation is not the design.
