I Have No Mouth, and I Must Scream

I Have No Mouth, and I Must Scream is a point-and-click adventure game based upon Harlan Ellison's short story of the same title. The game's story is set in a world where an evil computer named AM has destroyed all of humanity except for five people, whom he has been keeping alive and torturing for the past 109 years. Each survivor has a fatal flaw in their character, and in an attempt to crush their spirits, AM has constructed a metaphorical adventure for each that preys upon their weaknesses.
