Isotope

Isotope is a four-page mini-RPG about humans, mutants, strange animals, and techie trolls surviving in a post-apocalyptic future. It's my old-school homage to Gamma World, Metamorphosis Alpha, Mutant Future, and Encounter Critical. 

The game includes four classes, monsters, equipment, mutations, and a map of an abandoned missile silo ruled by a rampant AI. Have fun!
