Skirmisher Publishing is pleased to announce the release at DriveThruRPG of its “Ray Guns & Ruins” post-apocalyptic science fiction supplement! This 26-page dual-themed sourcebook by bestselling game developer Derek Holland is available by itself for just $2.99 and in a number of thematic discounted bundles, including a 50% off High-Tech Weapons Bundle, a 50% off Mutants Bundle, a 46% off Recent Releases Bundle, and a diverse 69% off Sci-Fi Sampler Bundle.

“Ray Guns & Ruins” is devoted to both descriptions and statistics for ray guns of all sorts, military and civilian, and material that can be used to make wastelands and ruins themselves, and not just their inhabitants, significant and interesting. Items of the latter sort include physical, chemical/energy, and superscience hazards; spontaneously-generated technology that can be used as rewards or dangers; guidelines on general and specific types of rooms that might be found anywhere in the wastes; and rules for drowning and suffocation.

Material in this supplement is stat’ed for the “Basic” OGL/d20 system and can be used as-is with OSR games like the Labyrinth Lord retroclone of D&D or the Mutant Future retroclone of Gamma World and is compatible with and easily adapted to games derived from that system and any others a storyteller sees fit.
