After about four years of Early Access, Barotrauma is finally out as a full-fledged release on Steam. The sci-fi submarine adventure have a new cinematic trailer available for you to view today if you aren't sure about what this game is about just yet.

In Barotrauma, players can go in alone or team up with others (up to 16 players per game) to explore the depths of Europa, one of Jupiter's moons. Players are tasked with undertaking a variety of missions and, in general, just trying to survive. FakeFish and Undertow Games have released a bunch of updates and content for Barotrauma since its initial release into Early Access back in 2019. A sample of the improvements made over the years include a complete overhaul of the campaign, tutorials, improved graphics and environments, new monsters, new missions and outposts, added a scripted event system, and more.

Levels are procedurally generated, there are some rather crazy ragdoll physics, and the game features full mod support. There's a lot to like here. Multiplayer can be fully cooperative or you can turn on "traitor mode" that will turn some of play pals into "secret conspirators, complete with their own individual missions like assassination or sabotage."

It looks like Barotrauma has a launch week discount of 25% off bringing the regular $34.99 (USD) price down to $26.24.

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.

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.

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.

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!
