I Have No Mouth, and I Must Scream

AM (as in "I think, therefore I am.") is an omnipotent supercomputer calling built by the Americans as the ultimate defense system, AM accidentally became self-aware and eventually goes insane. Linking up with its Chinese and Russian counterparts, AM destroys the entire human race except for five people: Gorrister, the suicidal loner; Benny, the deformed war veteran; Ellen, the hysterical phobic; Nimdok, the secretive sadist; and Ted, the cynical paranoid. These damned souls have been kept alive and psychologically tortured for years until AM begins a new game of metaphorical adventures based on each captive's fatal personality flaw.
