Cooperation. Chaos. Insanity. Horror. Barotrauma is all of this and more. One of the most unique, funniest, and terrifying coop experiences I've played. Only 3 things are for certain in Barotrauma;
1: You will die, and you will watch your friends die.
2: Everyone will eventually go insane, in and/or out of game.
3: The Doctor was lying. That wasn't Deusizine that was a lethal dose of Fentanyl.
