I Have No Mouth, and I Must Scream is an award-winning psychological horror point-and-click adventure game based upon Harlan Ellison's short story of the same name. Co-designed by Ellison and published by Cyberdreams in 1995, the game was a work of interactive fiction with psychological and ethical themes.
The game's story is a set in the world where an evil computer named AM that has destroyed all of humanity except for five people, who he has been keeping alive and torturing for the past 109 years. Each survivor has a fatal flaw in its character, and in an attempt to crush their spirits, AM has constructed a metaphorical adventure for each that preys upon their weaknesses. To succeed in the game, the player must make ethical choices to prove that humans are better than machines, because they have the ability to redeem themselves. Woven into the fabric of the story are ethical dilemmas dealing with issues such as insanity, rape, paranoia, vivisection and genocide.
