Corruptant

Summary

Chained up, locked away. Tortured and forgotten. At least that is how it has been for as long as you remember. Suddenly you are freed. Your mind is shredded, all memories lost to the overwhelming agony that you endured. The very people that imprisoned you demand for you to assist in preventing a looming threat, one that has the entire world at stake. Just who are you? Why were you imprisoned? What about those you knew? Remember it all and cope with the tattered remains of your psyche. Maybe even save the world. Or not, what has the world ever given you?

Corruptant is a dark fantasy interactive fiction game (book?) that sees you play a cursed amnesiac coping with the situation they find themselves in.
