Gamma World 1978 T-Shirt

Gamma World is a science fantasy role-playing game originally published by TSR in 1978. It borrowed heavily from an earlier TSR game, Metamorphosis Alpha. The details provided change from version to version, but from the beginning, Gamma World takes place in the mid-25th century, more than a century after a nuclear war had decimated human civilization. In the early editions, humanity achieved in creating a high-tech utopia that effectively ended human suffering and reversed man-made pollution. Early on, the setting was focused on finding the long-lost treasures of the fabled Apocalypse Base, but in truth, the setting was open-ended enough for a wide range of adventures.
