Saints Sinners: First major update out now

Hello, Hola, Cześć and Merhaba everyone!

The first major update for Barotrauma, with easier server hosting and a number of other improvements, as well as new languages, is now live. Find the changelog in full here, also included in the game folder in a file called "changelog.txt". Here’s a summary of the update:

- New server hosting method that no longer requires manual port forwarding
  • Click “Host” in-game to host a server through SteamP2P.
  • Can also join servers through Friends list.
  • Please note that hosting through DedicatedServer.exe will still use the old method of hosting and as such requires manual port forwarding.


- Optional griefing moderation tools (i.e. Karma)
- New Traitor system (feature framework, more content to be added later)

- Fixed issues (The most vexing ones! See all in the changelog):
  • Noticeable movement stuttering and low fps
  • Game crashes on start because of a missing DLL
  • Issues with picking up dropped items
  • Items cannot be combined in multiplayer
  • Combining items inside a Deconstructor crashes the game
  • Game crashes when refreshing server list multiple times before the list finishes loading


- Four additional languages
  • Spanish
  • Latin Spanish
  • Polish
  • Turkish


- New audio compressor and voice chat attenuation
- A new stock sub
- Modular decorative sub part sprite pack
- New items

You can also read more about the update in this earlier blog post.

Please note that the networking changes in this update will make the game incompatible with servers running on the old version of the game. In other words, server hosts, be sure to update so that others can join your server!

We hope this update solves a lot of the problems our players have run into since our launch. Let us know how we did!

P.S. The update is coupled with a Daily Deal for 25% off.

Karma Traitors update with easier server hosting

Hello everyone!

Barotrauma’s first major update will roll out on Monday, August 26, and we can confirm that easier server hosting will also make this update. Read on here about all the new features, fixes and items that will be included!

Sneak peek: Karma Traitors update

Hello everyone!

We’re happy to say we’re approaching the first big update for Barotrauma. Due to Gamescom and PAX West coming up, scheduling has been a little tricky, and we can’t promise an exact release date, but now you can read about what to expect. And as always, check our Trello for a summary of what’s to come.

The update will center on griefing moderation tools, and we’re hard at work with easier server hosting, to be added soon as well. We’re hopeful that these put together will significantly improve the multiplayer experience. Details about the new hosting method will follow closer to publishing it; read on here for more about keeping your servers nice and/or interesting.

Third patch out now!

Third patch out now!
We just released our third post-launch patch - still mainly focused on bugfixes, but there's also a couple of quality-of-life changes and additions. As always, you can find the full changelog on on GitHub and in the game folder. Here's a summary of the most important changes:
  • Improved server list. Can be sorted according to ping, name, compatibility or any of the other property in the list.
  • Improved character editor.
  • Fixed another ID mismatch problem that occasionally caused clients to get kicked out in multiplayer.
  • Fixed players always getting range banned when banned by a client.
  • More reliable fabricator and deconstructor syncing.
  • EXPERIMENTAL: option to disable rewiring items in multiplayer.
  • Fixed turrets not being aimed correctly in multiplayer if they're in another sub (e.g. the coilgun in Remora's drone).
  • Fixed the position of an outpost's docking port not being taken into account when determining how to place it in the level. Caused large submarines sometimes to collide with walls when docked to outposts where the port is offset from the center.
  • Reactors take other power sources into account when calculating how much power they need to generate. Fixes overloads on Humpback when turning on the backup batteries and operating the reactor normally.
  • Fixed ladders and other resizeable items reverting to their original size if they're resized and the sub is saved and reloaded.
  • Fixed inability to resize gaps in the sub editor after they've been placed.


Even though bughunting has kept us quite busy since the launch, the next big things on our todo list, simplified server hosting and improved anti-griefing mechanics, are also coming along nicely. If you want more info on what's to come in future updates, you can check out our Roadmap on Trello!
