WELCOME TO EUROPA

Barotrauma is a 2D cooperative survival horror game set inside a submarine simulator, drawing inspiration from titles like FTL: Faster Than Light, RimWorld, Dwarf Fortress, and Space Station 13. Set in a sci-fi universe, it fuses ragdoll physics with deep-sea alien threats, intense teamwork, and the ever-present shadow of existential dread.

PLUNGE INTO THE UNKNOWN

In the near future, Earth's survivors have escaped to Jupiter’s icy moon, Europa. Beneath its radioactive surface lies a hidden ocean teeming with danger and mystery. Traverse this merciless aquatic frontier, interact with four distinct factions, and uncover what ancient secrets lie buried in the abyss.

PLEDGE LOYALTY OR BETRAY YOUR CREW

Barotrauma offers as many ways to thrive as there are to perish. Team up with your crew to complete critical missions, or secretly undermine them as a traitor hellbent on destruction. Play alongside friends, strangers, or even those you’d rather see drowned—everyone has a role to play, and a price to pay.

NAVIGATE, OPERATE, SURVIVE

Chart courses through treacherous underwater terrain, carry out vital missions for humanity’s remnants, investigate forgotten alien ruins, and face terrifying sea beasts. Manage key submarine systems including sonar, reactor controls, weapons, engines, and life support. Survival depends on coordination—and clear communication.

DESIGN, BUILD, INVENT

Master intricate wiring systems and dive into advanced crafting and medical mechanics. Design custom submarines or engineer new horrors using built-in editors that rival official content. For the truly bold, pull back the curtain—access the source code and dive into modding.
