Core Mechanic	Decrease Dice — each character has one die, starting at d20, that serves as both their health and their resolution roll. To attempt a risky action, roll the die against the Difficulty your class assigns that skill; meeting or beating it succeeds, while a normal failure costs only the attempt. The die steps down a size (d20 → d12 → d10 → d8 → d6 → d4) whenever you roll a 1, take major damage, or voluntarily force the scale to convert a failure into an automatic success. A character whose die would drop below d4 falls Exhausted or dies; sleeping in a safe shelter resets it to d20 and consuming a sugar ration steps it back up one size.	Roll a pool of d6s equal to attribute + skill, counting 5s and 6s as hits. Meet or exceed a threshold to succeed. Situational advantages generate Edge points rather than modifying dice pools directly; Edge is spent on tactical effects like rerolling dice, adding successes, or imposing penalties on opponents.

Best For	Groups who want a quick, comedic one-shot or short campaign as thumb-sized survivors scavenging a household that has become a hostile wilderness, with a ruleset light enough to read in a few minutes before the first session.	Groups who want cyberpunk-fantasy heists with deep mechanical subsystems for hacking, magic, and combat.
Highlights	The Decrease Dice mechanic collapses health and resolution into a single die, so every roll both tests the action and visibly wears the character down as the die shrinks toward d4. Forcing the scale lets a player turn any failure into a guaranteed success by stepping their die down a size, making each clutch moment a deliberate trade of long-term stamina for an immediate result. Monsters are rated by a Threat Die that attacks and spells whittle down, and several — the chitin-armored cockroach, the static-charged dustbunny — shrug off ordinary weapons until players expose a weak spot or switch to fire, water, or magic.	Unique cyberpunk-fantasy setting blending megacorporate intrigue with magic and metahuman races. Dedicated subsystems for Matrix hacking, magic, rigging, and astral space. Edge system replaces many situational modifiers with a spendable tactical resource. Decades of published lore spanning in-world history from 2011 to the 2080s.
Considerations	Combat has no initiative or turn order — the GM narrates enemy intent and players react with defensive rolls — so there is little structure for tactical positioning. Rolling a 1 on any skill check — including routine Stealth, Alertness, or social rolls — steps the die down the same as taking a hit in combat, so avoiding unnecessary rolls becomes a survival strategy rather than a purely narrative choice. There is no advancement system: skills are fixed at character creation and the Decrease Die only ever recovers to its starting size, so characters do not grow mechanically over a campaign.	Matrix hacking runs as a parallel subsystem that can leave non-decker players waiting. Multiple supplemental rulebooks needed for full coverage of magic, Matrix, and rigging. Published books have documented editing and layout issues.
