The barotrauma command launches the client for Barotrauma, a top-down 2D multiplayer game focused on managing a submarine on Jupiter's moon Europa. Players face alien threats, flooding, oxygen shortages, and crew betrayals in a physics-based simulation. Developed with Unreal Engine 4, it supports single-player, co-op, and versus modes with modding support.

Invoking barotrauma starts the graphical client, loading campaigns, tutorials, or custom servers. It handles graphics rendering via OpenGL, Vulkan, or DirectX11 (emulated on Linux). The game emphasizes teamwork: engineers repair hull breaches, medics treat injuries, security combats monsters.

Common on Linux via Steam, Flatpak (flatpak run com.UndertowGames.Barotratrauma), or native packages in distros like Arch AUR. Requires a GPU supporting OpenGL 3.3+. Sessions are procedurally generated with escalating dangers from the Europan depths.

Linux requires OpenGL 3.3+ or Vulkan; Proton/Steam recommended for best compatibility. Server uses barotraumaserver. High CPU/GPU usage in multiplayer. Controller support via SDL.

Steam: steam barotrauma; Flatpak: flatpak install flathub com.UndertowGames.Barotrauma; AUR: barotrauma-bin.

Use barotraumaserver for headless hosting: barotraumaserver [port] [name] [password].

First released March 11, 2019 in Early Access by FakeFish/Undertow Games. Full 1.0 release March 10, 2023. Linux native support from launch via Steam. Active updates add content, balance multiplayer.
