Guide · Barotrauma ## Host a Barotrauma server Barotrauma is the co-op submarine survival game from FakeFish and Undertow Games, published by Daedalic. Up to 16 players crew a submarine under the ice of a frozen moon of Jupiter, keep the reactor running, patch leaks and fight what lives in the dark. 1up runs the official Linux dedicated server, downloaded from Steam and brought to the newest build every time the server starts. Settings, ranks and campaign saves live on their own volume, so a campaign carries on across restarts and updates. The server sits in its lobby until someone starts a round, and the Game tab chooses the mode, the player limit, the password and whether the server is listed. ### From an empty panel to your first dive 1. Open the panel, pick Barotrauma and choose any plan: the server starts on the Free plan. 2. Pick the game mode in the wizard; campaign is the default and keeps your progress between rounds. 3. Set a password if only your crew should get in, and turn the server browser listing off for a private crew. 4. Press start and follow the console: the first boot downloads about 300 MB and the lobby is ready within a minute. 5. In the game, open Join Server, press Direct join and paste the address shown on your panel. ### Joining from the game Players open Join Server and use Direct join with the address of your panel, or find the server by its name in the browser while it is listed. Every player needs the same game version as the server, so restart the server after a game update to pull the new build. ### Rules you can change from the panel The Game tab holds the game mode, the player limit, the password, the server browser listing and, on plans with mods, the Workshop items. Changes apply at the next restart. Everything else, from the submarine to the difficulty, is chosen in the lobby by the host or an admin. ### How much RAM Barotrauma needs The server is light: the lobby holds about 350 MB and a round with a full crew of bots about 550 MB. It starts at 2 GB, a full crew of sixteen is comfortable on 3 GB, and the game, the saves and a few mods fit in 5 GB of disk. ### Running the server as the owner Give yourself the Admin rank from the panel console with giverank, your player name and Admin while you are connected; Moderator is the lighter rank. Ranks are stored in Data/clientpermissions.xml and survive restarts. From the console you can also start and end rounds, kick, ban and talk to everyone with say. ### If something goes wrong If players get a version error, restart the server so it pulls the build their game runs. If a mod blocks joining, remove its Workshop id from the Game tab and restart. A campaign saves between rounds, so end the round in the game before you stop the server to keep the last dive.
