subtitle: Strange Science Fantasy Adventure in a World Gone Mad from What is Planet Psychon?: Basically when I got back into gaming after a long break I had to choose between Gamma World 2nd Edition and Cyclopedia edition of Dungeons and Dragons What you see here is not a fully resolved RPG. It is a setting you might use various systems to game in or just a source book of gonzo science fantasy apocalypse ideas to drop in a campaign. user note: Statistics, where present in this sourcebook, are patterned after early editions of D&D (classes, levels, familiar attributes, 1/2 axis alignment system, armor class).
