I Have No Mouth, And I Must Scream, which was based on the Harlan Ellison novella of the same name, is now available on Good Old Games. The game also featured vocal work by Ellison as the evil computer AM.
The game puts the player in multiple roles as the last people on Earth who are buried deep within the center of the Earth, at the mercy of a malevolent computer "AM". The gamer will play as Gorrister the suicidal loner, Benny the mutilated brute, Ellen the hysterical phobic, Nimdok the secretive sadist, and Ted the cynical paranoid, each of whom have been trapped for 109 years at the computer's mercy.
The game's graphics have been improved a little, with some anti-aliasing to get rid of the jaggies of the original 1995 game.
I Have No Mouth can be purchased for $5.99 USD at GoG.com.
