GAIN is a first person stealth game with perma-death. You play as Xavier, who is on a simple mission to not die. Each level contains a document which he has to collect and reach the exit the door. The only problem is that Xavier will die if he is shot at all. No regenerating health or health packs. He has to complete the missions flawlessly.
