Gonzo: Mad Science
This science-fiction supplement adds rules for time travel, black holes, mimic spaceships, werewolves in space, nanobots, exotic matter, and other theoretical physics concepts altered by magic. It includes three classes—the Replicator, Technician, and Time Traveler—along with five themes, the Chroma race and its religiotech subsystem, new archetypes, feats, spells, and expanded options for several existing classes. Additional content includes enemies, hazards, weapons, armor, equipment, consumables, ships, intergalactic siege weapons, new skill uses, and plot hooks. The material is aimed mainly at higher-level play and can be adapted for Pathfinder.
