WELCOME TO EUROPA

Barotrauma is a 2D co-op survival horror submarine simulator, inspired by games like FTL: Faster Than Light, Rimworld, Dwarf Fortress and Space Station 13. It’s a Sci-Fi game that combines ragdoll physics and alien sea monsters with teamwork and existential fear.
 

EMBRACE THE ABYSS

In the not too distant future, humanity has fled to Jupiter’s moon. With its irradiated icy surface, life can only be found in the ocean below. Travel through a punishing underwater environment and make friends or rivals of the four factions of the world. Discover what lies in the depths of Europa.

HELP YOUR CREW SUCCEED, OR MAKE SURE NO ONE DOES

There are as many ways to enjoy Barotrauma as there are ways to die in it. Work together with your crew to achieve your goals, or brace for betrayal when you have a traitor on board. Play with friends, strangers, or your worst enemies.

EXPLORE, OPERATE, COMMUNICATE

Navigate underwater, complete missions for the last remnants of humankind, explore the ruins of an alien civilization, flee or fight monsters. Operate complex on-board systems and devices like the sonar, nuclear reactor, weapons, engines and pumps. Communication is key!
