Winter Update preview & DLC sneak peek

All newsPlayers around this dateRead on Steam

Hello everyone!

As we’re closing in on the end of another year, it’s time to take a look at what Barotrauma’s Winter Update 2025 has to offer. Like our earlier updates this year, this one will also focus on fixes and improvements, with some new content sprinkled in.

What’s new in the Winter update


For the first time in a while, we’re adding a new vanilla submarine. The Wallaby, a new Tier 2 Attack class submarine, is a smaller sub with a surprising amount of firepower.The Wallaby also uses the new pipe weakpoint and valve system we are introducing in this same update. When a weakpoint bursts and starts spewing water, turning the valves can help in fixing the leak. However, any pumps connected to the valves will also stop functioning, so make sure your crew stays on top of things!The Winter Update will add a long list of fixes and improvements, including but not limited to:

  • Valves and weakpoints: Pipes can burst due to impacts with walls or being rammed by monsters, causing a water hazard. Burst pipes can be more easily repaired by shutting off their associated valves. The downside of closing a valve is that it also disables any linked pumps.

  • Multiple timeout threshold changes to reduce errors like “timed out”, “expected old event” and “expected removed event”.

  • Fixed characters sometimes suffocating or dying if loading into the round takes a long time.

  • Fixed AFK setting staying enabled when a client loads a campaign, causing them to load into a round with no character.

  • A possible fix to the game freezing around the 80–95% mark of the loading screen.

The Winter Update will be released early next week. Stay tuned!

Home and Harbor DLC sneak peek


We’ve been hard at work on the Home and Harbor DLC and wanted to share a few cool additions with you before the year is out. We'll go into more detail later on the bigger new systems and features we've been working on, such as the outpost building, economy and combat changes, but here’s a sneak peek at a couple of Descendant submarine technologies.The singularity reactor

A new, cleaner alternative to a nuclear reactor for power generation. It’s simple, really: the larger the singularity, the more power it creates. But be careful, as a powerful singularity is also more unstable, and prone to escaping containment to wreak havoc around your submarine. DO NOT PUT YOUR HANDS INTO THE SINGULARITY. They might come off.

Swarm torpedo launcher & the Thales Cannon

The Descendants can help outfit your submarine with highly advanced armaments. The swarm torpedo launcher fires a torrent of small torpedoes in rapid succession, which you can then guide to a target of your choosing with an integrated laser guidance system on the turret.

If you prefer a more up-close and personal approach, try the Thales Arc Cannon. This large turret releases a short range burst of lightning, ideal for dealing with groups of hostiles as the lightning will chain from enemy to enemy in an electric display of destruction.

What do you think so far? More information about the Descendant faction and the Home and Harbor DLC will be coming your way next year.

Holidays on Europa


Following the release of the Winter Update next week, we will monitor the bug situation for a while and hotfix any serious issues, as usual. After that, we will head for holidays and be closed for business for a couple of weeks around Christmas. We wish you all a beautiful and relaxing festive season and will see you again in January. Happy holidays, everyone!
