OUT NOW!!
The UAC, after the demonic invasion, has had various of his remaining marines mentally scarred by the invasion, in such a way that UAC employees have to recover the marines' sanity in case another invasion happens. You are one of the mentally tortured marines, who are subject to the Mindprison Project, project code 4989, which sets you into a mind reality where you have to fight your own demons and the trauma caused by the demonic invasion, aside of getting rid of the demonic influence that has invaded your mind.
MINDPRISON PROJECT is a megawad project designed singlehandedly by JMAA in the likenesses of Plutonia and other extremely difficult DOOM 2 megawads and expansions.
Note: you need a legal copy of DOOM 2 to be able to play this
Or download it on ModDB
