Planescape: Torment

A sinister AD&D fantasy RPG produced by Guido Henkel (Realms of Arkania games), Planescape Torment is powered by the Infinity engine that was also used in the Baldur's Gate series and Icewind Dale.

You play a scarred, amnesiac immortal in search of his identity. You awake on a cold stone slab in the Mortuary of the City of Sigil. You have no idea how you got there, who you are, or any of your past identity(s). You must escape and explore the strange world to uncover the secret of your death and rebirth...
