Ray Guns & Ruins
This supplement provides descriptions and game statistics for military and civilian ray guns in a post-apocalyptic science-fantasy setting. It also expands wastelands and ruins with spontaneously generated technology, rewards, dangers, mundane and superscience hazards, and guidelines for rooms found throughout the wastes. The material uses the Basic OGL/d20 system and is suitable for OSR games, including retroclones of fantasy and post-apocalyptic role-playing systems, with adaptation for other compatible games.
