Server hosts ahoy!
We've now got Barotrauma's dedicated server available as a separate app that can be installed and run using SteamCMD in anonymous mode. This means that you can now hosts dedicated Barotrauma servers on your server machine without having to log into Steam. You can find instructions for installing and running the server in this pinned post on the Help & Support forum. Do note that this method of hosting servers is a little more complex than hosting servers via the in-game "Host server" menu or the dedicated server executable included with the game. It's mainly intended for people who want to run a dedicated server 24/7 on a remote machine.
And now that we're on the subject of server hosting, a quick word about the hosting in general. We are aware that many people are having issues setting up port forwarding for the servers, and a solution to this is admittedly something that we should have made sure to include in our first public Steam build. We are currently working on using Steam's networking features to remove the need for manual port forwarding, so server hosting will become much more easier soon in upcoming patches. For the time being, if you're having issues hosting a server, please read the instructions on the Help & Support forum, and if you're still having problems please drop a message on the forums or on our Discord Server.
