Lobotomy 2: Manhunt

From Titan Forge:

Lobotomy 2 is a fully cooperative dungeon crawler. Players become patients trying to escape from a mental asylum set in a survival horror theme. Unravel all the mysteries by playing a story-driven campaign or set up a game in a Daily Nightmare mode with unlimited replayability. You will choose from a diverse cast of characters whose power grows along with their insanity. But is the hospital staff really a bunch of monsters? Are ordinary objects actually mighty weapons? Or is it all just in your heads?
