From the developer:
Barotrauma is a 2D online multiplayer game taking place in a submarine traveling through the icy depths of Jupiter’s moon Europa. The bone-crushing pressure outside the submarine, the strange creatures inhabiting the ocean and the potentially dangerous equipment and machines on board ensure that the tiniest slip can turn the game into a chaotic struggle for survival.
Barotrauma takes place several hundred years in the future.
