About Barotrauma

✦ AI summary

Pilot a submarine through Europa's hostile alien ocean with up to 16 players, managing complex systems and monsters while deciding whether to cooperate with your crew or sabotage them for survival. It's a co-op roguelike that blends tactical team gameplay, physics-based chaos, and deep sandbox customization where betrayal is always an option.

"Work together to explore and survive, and/or sabotage one another and let the ship go down in fire and flood."
- Rock Paper Shotgun

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!

EXPERIMENT, CRAFT, CREATE


Master the complex on-board wiring and the comprehensive crafting and medical systems. Create your own submarines and monsters with built-in editors to rival the standard ones. Even tap directly into our source code and mod away.

Me and my friend beat up some ruffian prisoners with shock batons to the brink of death. After the beatdown we locked them in a room and noticed we have to resuscitate them because our stern discipline was a bit too harsh. All this was for naught anyway because the ♥♥♥♥♥♥♥♥ orca submarines lower cannon is such ♥♥♥♥♥♥♥♥ placed that you cant protect half of the ♥♥♥♥♥♥♥♥ piece of ♥♥♥♥ from the never ending mudraptor onslaught. Also the ai crew is extremely stupid and act like fools when the submarine fills with water. The ♥♥♥♥♥♥♥♥ ♥♥♥♥♥♥♥♥ always die to pressure or they seek the most dangerous spot where they will be getting mauled by the ♥♥♥♥♥♥♥♥ mudraptors.

Very fun game, however the prisoners need to learn some discipline and obedience for their captors. They were running around like headless chickens and desperately scavenging for any sort of weapon, however our disciplinary methods proved sufficient, because we had disciplined them until they submitted and could be dragged to our makeshift prison where they were put on oxygenite to preserve their lives.

my friends were trying to lock prisoners in the crew quarters but they wouldnt go there willingly so they decided to show a bit of "discipline" and proceeded to beat them to deaths door it got so bad we had to use oxegynite go bring them back after dragging them to the crew quarters very fun would let my friends do it again
