FakeFishGames/Barotrauma ? reverse-engineered prompt

Build me the Barotrauma game project so I can open it and run it locally. I want the full submarine multiplayer game to compile cleanly, and I’d like the setup to work on my machine with whatever the repo already expects for Windows, Linux, or Mac.

Please check the README and any existing build instructions, then get the solution working end to end. If anything depends on current docs or missing setup steps, look them up online and use the latest guidance. After that, make sure the game launches without obvious errors and tell me the main steps to build and run it from the repo.
