After the Blast

Centuries after nuclear war scorched the earth, survivors eke out existence among shattered cities, radioactive wastes, and roaming mutants. The world blends retro-future technology with desperate scavenging—vault dwellers emerge into blinding sunlight while wastelanders fight over pre-war scraps.

Theme and Setting

Factions war for territory, ancient machines hum with dangerous energy, and every shadow might hide something hungry or mutated. Resolution uses 2d6 + relevant stat against target numbers set by the GM.

How Play Feels

Characters choose from archetypes like Vaultborn, Wastelanders, Raiders, Ghouls, and Mercenaries—each with unique starting gear and background hooks. The Radiation & Mutation System adds risk to exploration: exposure triggers mutation rolls that grant strange powers at physical and mental costs.

What Makes It Distinct

Combat is quick and deadly, favoring tactics and resourcefulness over character durability. The included hex-crawl tools let GMs generate ruins, hazards, and faction territories on the fly.

Where It May Not Fit

You want a cleaner, less pressured world state You want the system to stay almost invisible at the table.
