Only ten percent of American birn mutants live to see their twentieth birthday. Some are attacked by frightened neighborhood mobs, many murdered in confrontations with other mutants, but most have been executed by the U.S. Government''s homo-superior extermination androids: the Sentinels. Throughout America, desperate and fearful mutants have banded together in small groups, living under the streets ogf our largest cities where they remain hidden from sentinel detection. They do not want to be heroes or villains, they only hope to survivce. More tan just an urban legend, less than the horrific monsters America proclaims them to be.
