Barotrauma Host Rotation Guide - Take Turns Captaining the Sub

Thu, 27 Aug 2026 00:00:00 +0530

Barotrauma crews rarely settle on one permanent captain for long - people go on holiday, keep different hours, or just want a turn running the sub instead of always being the one stuck in engineering. The trouble is that a self-hosted Barotrauma campaign keeps its save on whoever’s hosting, split across two files, and handing that off cleanly by hand is where crews usually get it wrong.

Why Rotating Hosts Is Hard by Default

Barotrauma writes your campaign to %LOCALAPPDATA%\Daedalic Entertainment GmbH\Barotrauma\Multiplayer as a pair of files: <save_name>.save and <save_name>_characterData.xml. Rotating who hosts means moving both files to the next player’s machine, every time, without missing the character data or overwriting it with an older copy. Miss one file, or send a stale pair, and someone’s talents or inventory quietly roll back.

Barotrauma Save Sharing Guide - Let Any Player Host the Sub

Barotrauma drops up to 16 players into a submarine in a hostile alien ocean, splitting the crew between captain, mechanic, medic, and whatever else keeps the hull from flooding. The multiplayer campaign is where the game really lives - a persistent crew, a persistent sub, and a save that carries scars from every close call. The problem is the same one every host-based co-op game runs into: that campaign save sits on one player’s machine, and the crew is grounded whenever that player isn’t around.

How to Continue Barotrauma When Your Host Is Offline

Your Barotrauma crew just survived a hull breach, patched the reactor, and limped into the next outpost - a great note to stop on. Next session, half the crew is online and ready to push further into the trench, but the person who hosted last time isn’t around. So the sub sits docked.

If you’re self-hosting rather than renting a dedicated server, that’s not a bug - it’s just how Barotrauma’s campaign save works.
