Barotrauma
Barotrauma is a 2D online multiplayer game taking place in a submarine travelling through the icy depths of Jupiter’s moon Europa. The bone-crushing pressure outside the submarine, the strange creatures inhabiting the ocean and the potentially dangerous equipment and machines on board ensure that the tiniest slip can turn the game into a chaotic struggle for survival. The game is heavily inspired by Space Station 13 and a game concept called Pressure.
Barotrauma is a 2D co-op submarine simulator – in space, with survival horror and RPG elements. Steer your submarine, complete missions, fight monsters, fix leaks, operate machinery, man the guns and craft items, and stay alert: danger in Barotrauma doesn’t announce itself!

Why Barotrauma mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Barotrauma mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
