Dementium II

You are William Redmoor, recent recipient of a radical brain operation
intended to cure psychosis and current inmate at a clandestine treatment
center for the criminally insane. Your memories are fuzzy, but it
appears that your wife was murdered, and the evidence pointed toward you
as the killer. Here at the Bright Dawn Treatment Center you are under
the care of an enigmatic figure known only as The Doctor.

Whatever the Doctor’s methods, they appear to work—your psychosis is
gone… or is it? Demons you once battled have appeared once again. Worse,
it seems that the Doctor has some diabolical scheme to perform
experimental operations on scores of other inmates. You must not only
survive an onslaught of horrific beasts but also stop the Doctor from
achieving his goal. With all the insanity that surrounds you, you can’t
tell if it’s you or the world around you that has truly lost it. Just
how demented are you?
