"Gammarauders" takes place in the distant future during a time period called the Gamma Age. Nuclear war has devastated much of the world, leaving a few pockets of civilization separated by vast expanses of wasteland called "The Big Nada." Two major power groups formed after the war: The Gammarauders (who seek to rebuild the world) and the Slugnoids (who seek to dominate it). Among the ranks of the Gammarauders is a man named Professor Womba, inventor of the Womba Process. This process allows scientists to create bioborgs by mutating animals and implant them with nodes that can be fitted with weapons. The Slugnoids kill Womba and steal his research, allowing them to develop their own bioborgs as well.
