Gammarauders is a post-apocalyptic board wargame published by TSR, Inc., in which players acted as the human handlers of giant mutant creatures called bioborgs. The game also had a 10-issue comic book series that was published by DC Comics. Three of these comics also featured a "micro-RPG" installment that allowed readers to create their own bioborgs and handlers. Despite its normally grim post-apocalypse setting, the game and comic series had a humorous atmosphere. An expansion set called Revenge of the Factoids was also released. It contained new bioborgs, new types of military units, and new types of terrain.
