How co-op works
Up to sixteen online players crew one submarine as captains, engineers, mechanics, medics, security officers, or assistants. During procedural missions they navigate by sonar, manage the reactor and pumps, repair leaks and wiring, treat injuries, craft supplies, and repel creatures; bots can fill empty roles.
About this game
Barotrauma drops your crew into a submarine navigating the hostile ocean floors of Europa, where every voyage blends methodical simulation with survival horror. This is true cooperative multiplayer: each player takes a specialized role, from captain and engineer to medic and gunner, and the sub only survives when everyone works in sync.

You will steer through dark waters, repair hull breaches mid-mission, fend off alien creatures, operate complex machinery, and scavenge resources to keep systems running. Communication is essential because danger rarely waits, and a flooded reactor room or a monster breach can spiral into catastrophe if the crew does not coordinate fast.
Barotrauma supports online co-op and online PvP across Windows, Mac, and Linux, with missions that reward careful planning and quick adaptation. Every session becomes a high-pressure test of teamwork, where one mistake can sink the whole boat and every successful run feels earned.

Frequently Asked Questions
Do we all need to be on voice chat to play effectively?
Yes, communication is essential. Barotrauma is explicitly communication-heavy: coordinating repairs, operating machinery, and responding to emergencies like hull breaches or monster attacks requires constant teamwork. Voice chat will make coordination much smoother than text alone.
Can I play this solo, or is it multiplayer-only?
The game supports single-player as well as multiplayer, so you can pilot a sub alone or with AI crew. That said, Barotrauma is designed as a co-op experience, and the tension and teamwork really shine when you're coordinating with real players.
Is this more about combat or managing the submarine?
It's both. You'll fight alien creatures and deal with threats, but survival depends just as much on resource management, repairing systems, operating machinery, and keeping the sub functional under pressure. Think simulation meets survival horror with strong RPG and crafting elements.
Does it have mod support or extra content?
Yes, Barotrauma supports Steam Workshop, so you can browse and install community-created mods, submarines, missions, and other content to expand your experience beyond the base game.
