From the game box back:
Can you survive in a world gone mad? A world where civilization as we know it has been destroyed in a cataclysmic holocaust? What is left in this world? Find out and encounter such bizarre things as mutated plants and animals more terrible than you can imagine, radiation wastelands that stretch as far as the eye can see, and fearless machines gone uncontrollably berserk...
This is the setting for a GAMMA WORLD campaign, with players taking on the persona of an individual character somewhere in this forbidding locale. On a quest for survival and in search of a better future, the players adventure across the land, enduring hardships and encountering dangerous obstacles and mysterious foes - never knowing quite what to expect. The result is a game which can go in many directions, but which will be challenging and fascinating no matter what the outcome.
The GAMMA WORLD Set includes all the basics needed to set up your own "world": game booklet (packed with terrible mutants, as well as guidelines for creating additional ones of your own), a large campaign map (designed to be easily modified by individual gamemasters), and a full set of polyhedra dice. The only other things necessary are a good imagination and a spirit of adventure! The GAMMA WORLD rules are also suitable for use with the ADVANCED DUNGEONS & DRAGONS rules.
The GAMMA WORLD challenge awaits you - are you ready?
