Worlds of Atomic Horror

A GURPS supplement for running retro-futuristic science-fiction and horror campaigns set in alternate Cold War-era worlds. It presents four alien groups with distinct technologies, methods, templates, and statistics, along with organizations, five linked alternate worlds, and detailed setting histories. The book also includes mutation tables, ideas for time machines and experimental transformations, and references to inspirational films, television, games, and other media. It supports campaigns involving nuclear technology, alien influence, monsters, and the chrome-tech future imagined by early science fiction.
