As one of technology’s four horsemen, radiation is a important part in Mutant Future and other post-apocalyptic and sci-fi games: hazard, theme, bringer of mutation, waster of civilizations. The game mechanics assume a single kind of radiation, which reacts in a single way with the human, animal, or mutant plant body. But in real life, this isn’t the case. Radiation comes in different forms, with different intensities and different ways of being used or causing harm. This issue considers these different types of energy, and introduces many possibilities brought by a few hundred years of scientific progress, industrial ingenuity, and alien contact.

This publication is dedicated to providing useful information, game content, and ideas to players of modern, science fiction, and post-apocalyptic table-top and role-playing games in general and to fans of Goblinoid Games’ Mutant Future retroclone of classic Gamma World in particular.
