Total Chaos is a total conversion mod for Doom 2 that runs on the GZDoom source port. The mod is a survival horror set on a remote island known as Fort Oasis. The island was once run by a community of coal miners which one day suddenly disappeared, leaving behind the abandoned concrete jungle to waste away. Something, clearly, has gone very wrong with this place. Upon your arrival at Fort Oasis, you receive a strange radio transmission. Someone wants to be found.
