Phantasmagoria 2: A Puzzle Of Flesh (ISO)

You play the role of Curtis Craig, a 30 year-old man whose distorted childhood is filled with horrors - his dad was involved in an illegal, top-secret experiment for WynTech Industries, an experiment whose true nature is revealed only as the game progresses, and whose evil nature left Curtis' mother out of her wits and eventually drove her to suicide.

Curtis' father was later shot, leaving the poor little boy with serious behavioural disturbances, and eventually in therapy. Now, a year after having been released from the mental institution, Curtis is employed at WynTech Industries (whose manager, Paul Warner, has taken it upon himself to take care of Curtis) and tries to find out the cause of his psychotic episodes and the mysterious murders that break out all around him, all the while finding out more and more about his past life and his father's fate.
