Hotfix v1.9.8.0 for the Summer Update 2025Jul 1, 2025 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/abb5e9d35633306eefba92ff5c5657eee957cee3.png Hello everyone! We have just released a hotfix to address issues in the Summer Update 2025. Find the full list of changes below, and make sure to update your game to the latest version to receive the fixes. v1.9.8.0 - Fixed RegEx components occasionally timing out for no apparent reason (even if the expression isn't particularly performance-intensive). Seemed to have been caused by RegEx changes in .NET 8. - Fixed the game sometimes freezing for a long time at a specific point during the loading screen. Only affected some players: the issue had to do with the game failing to connect to a server to check whether the player has given their consent collect gameplay analytics. - Fixed streamed sounds always starting from the beginning when they're re-played. Particularly noticeable in the night club modules, when the music always starts from the beginning if you step outside the range of the sounds. - Fixed distance attenuation and positioning not working on the music played by jukeboxes and bar speakers (meaning they'd play at full volume regardless of your distance to the speakers). Modding: - Fixed oneshot delayed effects (which should only ever trigger once) still continuing to run some of the logic after the first trigger, causing an unnecessary performance hit. Did not seem to affect any vanilla items. Summer Update 2025 out now!Jun 17, 2025 - Community AnnouncementsHello everyone! This year’s Summer Update has just been released, with a long list of fixes, improvements and small additions. Here are some of the highlights: Support for Steam Timeline: When you record gameplay directly within the game using Steam’s Timeline feature, the game adds markers about notable events in the game. The new Rifle Scope will help some weapons in long-range battles. Power Distributor with 8 power outputs and sliders that can be used to control how much of the input power is distributed to each output. Scaling and rotation tools to the submarine editor. Pet improvements submitted by Uberpendragon. (Thank you!) A few new optimizations 46 bugfixes, including this fun one: “Fixed ’fake fires’ you see when under psychosis sometimes turning into real fires in single player.” See the full list of changes below and be sure to update your game to the latest version to be able to host and join servers! We hope you enjoy the improvements in this update, and stay tuned for more content additions to come later. We’re going to be around for a while longer to see that the update runs smoothly, and soon after we will log off for some summer holidays. We’ll be back in action in August and wish everyone a beautiful and relaxing summer! v1.9.6.0 Changes and additions: - Added Power Distributor item. Includes 8 power outputs and sliders that can be used to control how much of the input power is distributed to each output. Can be used to, for example, build a circuit that redirects power from less vital systems to weapons or pumps in an emergency. - Added Rifle Scope. - Better Steam Timeline support: when recording gameplay using Steam, the game adds markers about notable events in the game. - Added scaling and rotation tools to the submarine editor. Enabled using buttons in the top-right corner of the editor. - Characters don't throw flares when also holding a ranged weapon (allows shooting with a flare in hand). - Improvements to pets (kudos to uberpendragon): improved ragdolls and animations, gave them head slots so they can wear hats, added damage modifiers to shells. - Mindwipe resets the extra talents gained via the assistant's Apprentice talent tree, preventing the use of Mindwipes as a way to make an assistant unlock the specialization trees of all classes. - Alien Blood is now less powerful, by curing less "Bloodloss" affliction and causing more psychosis. It is widely available and made saline and blood packs pretty redundant. It now also requires more medical skill. - Added option to filter by name and to change the sorting of the save files listed in the "load game" menu. - Made circuit boxes' external connections (the once that hook up to other items) use the same labels that have been set inside the circuit box. - Made the freecam console command a toggle: entering it again gives you back control of the character. - Added "loslightingfreecam" console command (convenient for testing, executes those 3 commands). - Upgraded to .NET 8...Spooky 2D co-op submarine sim Barotrauma is getting a big Home & Harbor expansionJun 10, 2025 - GamingOnLinuxDaedalic Entertainment and developers Undertow Games and FakeFish recently revealed the Home & Harbor expansion for Barotrauma.

We have just released a hotfix to address a number of issues with the Calm Before the Storm update. Find the list of changes below, and remember to update your game to the latest version to receive the fixes! v1.8.8.1 - Fixed client list often appearing empty in the server lobby when joining mid-round while a campaign was active. - Fixed job variant selection panel rendering below the job selection panel, often making it unusable. - Fixed job variant selection only working in the server lobby, not in the tab menu mid-round. - Fixed inability to preview loadouts if there's only one variant of a job available (e.g. assistants). - Fixed fires no longer spreading from room to room. - Fixed a pathfinding issue that sometimes caused both to get stuck running back and forth towards the target they're trying to reach (one common place where this occurred was Barsuk's engine room). - Fixed non-hitscan projectiles such as harpoons launching with an incorrect rotation when fired to the left. - Fixed Herja not having any assistant or non-job-specific spawnpoints, causing assistants and custom classes to spawn at other classes' spawnpoints, potentially giving them ID card tags they shouldn't have. - Autoinjectors no longer inject meds on dead characters (even though they are technically below the health threshold at which the autoinjection should trigger). - Fixed team argument not working on the "spawncharacter" console command when spawning non-humans. - Fixed some edge chunk objects in hydrothermal wastes and the great sea spawning in front of the level walls. - Fixed missing gap in one of the new crew modules, which prevented water and oxygen from flowing through the module properly. Modding: - Fixed transferring afflictions to a newly spawned character using status effects causing a crash if the original character had already been removed. Didn't affect any vanilla content.Co-op submarine survival simulator Barotrauma has a free weekend on Steam, so dive in with friends and experience the most comically horrifying deaths you can imagineApr 17, 2025 - PC GamerQuick story about the most nightmarish death I've ever experienced in a videogame: I was playing Barotrauma, the submarine survival simulator where you explore oceans on alien worlds.

We have just released a hotfix to address issues with the Calm Before the Storm update. Find the changelist below, and remember to update your game to the latest version to receive the fixes! v1.8.7.0 - Fixed an AI bug that made bots scared of water, making them seek safety from flooded rooms even when they were wearing diving suits. - Fixed non-hitscan projectiles registering hits with characters that are behind the weapon, even if the barrel is in front of the character. - Fixed submarine maintaining an incorrect position (= starting to steer somewhere completely off) when you enable "maintain position" and then enter a new level. - Fixed autopilot failing to navigate to a destination if it's already on at the start of the round. - Fixed dedicated server descriptions still sometimes getting truncated. - Fixed lights shining out from items inside character inventories. - Fixed inability to access the inventories of other players when they're manually ragdolling. - Fixed "firing blanks" traitor event requiring you to replace standard coilgun ammo boxes with fake ones, instead of accepting any type of coilgun ammo. - Fixed switches flipping around when you attach them while facing left. - Fixed grenade "cooking" hint not showing the correct keybinding (just saying instead of the actual keybinding). - Fixed main menu notifications (changelog, unstable info) staying open if you don't manually close them and e.g. start a new game or go to the sub editor. - Fixed normal outpost events triggering in outpost that have been abandoned because of Jovian Radiation.'It’s about to get even darker, more disturbed, and violent': Barotrauma's Calm Before the Storm update introduces new PVP outpost and alien ruinsApr 13, 2025 - PC GamerIf you've ever wanted to perish in undersea alien ruins on one of the moons of Jupiter, now's your chance thanks to the latest update for 2D co-op horror game Barotrauma...

The Calm Before the Storm update has just been released. It includes the new Reserve bench feature, improvements to Jovian radiation, new and improved abandoned outpost modules, new loading screens, level backgrounds and background creatures, plus a long list of bugfixes, optimizations and bot AI improvements. You can read more about the update in our previous post and check out the full list of changes below. Make sure to update your game to the latest version in order to join and host servers, and enjoy the Calm Before the Storm! v1.8.6.2 Changes and additions: - Added PvP versions of outpost levels for all biomes. Previously the outpost deathmatch rounds always used cold caverns levels despite the biome setting (which doesn't make much difference in the vanilla game since you don't usually go outside, but can be more relevant in custom outpost deathmatch missions). - New alien ruin "outpost" for the outpost deathmatch mode. - Reworked the loading screens with new handmade art. - Visual improvements to cold caverns and great sea. - Reworked the decorative "background fish" that wander around in the levels. - One small endgame lore related outpost event. - Renamed and recategorized a bunch of structures to make them easier to find in the sub editor. - Reworked abandoned outpost modules, added 14 new modules. Kudos to NotWendy! - Reduced the health of outpost security. - Outpost security can spawn more batteries and ammo for themselves (making them better at defending themselves, compensating for the reduced health). - Reorganized abandoned outpost mission types in the server lobby screen (separate types for assassination, destroy monsters, rescue and destroy outpost missions). - Increased outpost wall health and made the junction boxes in outposts more resistant to overvoltage. - Improvements to fabricator UI to make it dump less information on the player (especially new players): more options for sorting the items, option to only show the items you can currently fabricate. - The console commands heal, teleportcharacter and godmode accept “/crew” and “/me” as arguments (making the command apply to either the whole crew or your current character). - Added “killall” console command: kills every character in the level (players, NPCs, monsters). - Added “spawnnpc” command: spawns a pre-configured NPC from a prefab. - Added some sounds and particle effects to drinkable/edible items. Reserve bench - Added “reserve bench” feature to multiplayer campaign: bots can be hired to a “reserve bench” instead of active duty, which means they won’t spawn until a player chooses to take them over after dying in the permadeath mode, or until they’re moved to active duty in the HR manager interface in an outpost. - Allows hiring bots as “backup characters” for the permadeath mode, without having to have the bots as active characters in the crew. - Also usable when permadeath is ...Coming next week: Calm Before the Storm updateApr 4, 2025 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/e7be13a1063ab67a617c4e1af591c50422c99d00.png Hello everyone! The Calm Before the Storm update is coming next week, so let’s have one last glance at what’s gathering on the horizon. Reserve Bench: Hire bots into reserve, to be called into active duty later. Bots can be called into active duty at the HR manager, or when you lose a character in Permadeath mode. Visual improvements: Keep your eyes peeled for new loading screen images, level backgrounds in the Cold Caverns and the Great Sea, and new background creatures swimming in the distance. Jovian radiation improvements: The intensity of the radiation will ramp up quicker the deeper you are in a radiation zone, and will eventually become too strong to withstand even in a hazmat or PUCS suit. Some monsters will also get stronger when irradiated, adding to the danger. Improved abandoned outpost modules, and 14 entirely new modules contributed by NotWendy. Three new alien ruin modules, a new ruin mission, and fixes to alien ruins. A new alien ruins themed outpost for the Outpost Deathmatch mode. Minor rework of the Remora sub, plus fixes to the Kastrull, Winterhalter and Typhon subs. Various optimizations, and fixes to multiplayer syncing issues to reduce the amount of rubberbanding in combat. A long list of bugfixes and improvements to bot AI. An even longer list of general bugfixes and QOL changes. Read more about the update now on our blog, and get ready for the release next week!Test the spring update now in the Unstable betaMar 14, 2025 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/abb5e9d35633306eefba92ff5c5657eee957cee3.png Hello everyone! Now that spring is slowly thawing the land (and the bones of our dev team), it’s soon time for Barotrauma’s first update of the year. The update is currently being tested by our team, and you can also start test driving it now and give us feedback before it’s released! There’s an important new feature coming in this update which we would be happy to hear your thoughts on: The ‘Reserve bench’ feature allows you to hire bots as ‘backup’ crew members, who only spawn when needed, for example after a player death in the permadeath mode. You can also use the reserve bench outside of permadeath, for example to keep a skilled engineer handy, just in case your current one meets an untimely end. There are also other content additions coming – more about these a little later! In the fixes and improvements department, here are some of our favorites: Fixes to syncing issues in multiplayer combat, greatly reducing the amount of desync and rubberbanding. A long list of improvements and bugfixes to bot AI. Addressing issues with ladders, stealing, being set on fire, targeting and more! Various optimizations You can already test all of the upcoming changes in our Unstable beta version, which you can access through your steam client. Simply right-click on Barotrauma in your Steam library, select “properties” and from the dropdown menu in the Betas section, select the “unstable - Public unstable version” and run the game. For more testing information, check out this forum post. Get a deeper sneak peek into the update on our blog, take a look for yourself in the Unstable beta, and stay tuned for the release in a few weeks!Welcome to Europa, 2025Jan 31, 2025 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/abb5e9d35633306eefba92ff5c5657eee957cee3.png Hello everyone! As we set sail into 2025, we wanted to give you some early insights into our plans for the year ahead. Our work on Barotrauma continues, but we are going to shift gears and move towards less new content, and more changes that help to polish and improve the game. This spring, we will be releasing a content update made up of various features and changes that had to be left out of earlier updates for one reason or another. You can look forward to a submarine rework, new events and missions, an additional PvP outpost, and more. We’ll preview this update properly a little closer to its release. Following the spring update, we have no major content additions planned for some time to come. Instead, the later updates of this year will introduce fixes, improvements and small changes – and possibly some content additions as well, when our schedule allows it. This isn’t the last you’ll hear of new content in Barotrauma, though. We still have plans and will tell you more about them a little later! For now, stay tuned for the spring update in March, and check out our blog for some more greetings from our team. Happy 2025!Daedalic Publisher Sale 2025Jan 22, 2025 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/29c2603a7863dee39ec36ab79cc83f0a08cd3cdf.png Greetings everyone!

We wish everyone a beautiful and relaxing holiday season. See you again in January! {STEAM_CLAN_IMAGE}/33962671/2286b42101d4ac1ee247f91af6db92047576b201.png v1.7.6.0 Changes: - Added a "toggle run" input (so you no longer have to keep holding shift to run). Not bound to anything by default, but can be set in the settings menu. - Improvements to environment visuals: the inside of level walls fades to black to make the texture tiling less obvious when zoomed far out, improvements to the shapes of the level walls (more natural shapes, less long and straight wall segments). - Ruin scan missions show a progress bar indicating the status of the scans. - Made dry or partially dry rooms more common in wrecks. - Option to change the sound of the alarm sirens to a claxon horn sound (the "traditional" AWOOGA-AWOOGA submarine alarm sound). - "giveaffliction" console command now auto-completes identifiers as well as names. - Reworked Berilia (kudos to WJohnston): layout improvements, added a bottom docking port, more windows, replaced cameras with searchlights, simplified battery setup and increased reactor output, minor visual improvements and a lot of miscellaneous tweaks. - Reworked Kastrull drone (less ugly, a little sturdier, the ballast can be accessed through a hatch). - New playstyle banners. - Added an option in the settings to launch the game on a specific display. - Option to refresh the available audio devices (both playback and input devices) in the game settings. The game should now also automatically attempt switch to another device if the current one is disconnected. However, whether this can be done automatically can depend on the audio device, driver and the operating system, and in some cases it may be necessary to choose a new device manually from the game settings. - Made electrician's goggles easier to get (spawns as a part of the sub's initial supplies, can be purchased from outposts, doesn't require fulgurium to fabricate). The goggles are intended to help less experienced engineers get a hang of wiring in particular, so it doesn't make sense for them to be so difficult to get. - "Safe rooms" are no longer indestructible in beacon stations (felt confusing, especially when it wasn't apparent from the look of the walls). - One new research outpost events to foreshadow the longer ruin event chain. Optimization: - Rendering optimizations...Coming next week: Winter Update 2024Dec 5, 2024 - Community Announcements{STEAM_CLAN_IMAGE}/33962671/2286b42101d4ac1ee247f91af6db92047576b201.png Hello everyone! It’s almost holiday time, and so it’s also almost time for our yearly Winter Update. This time it will be more of a patch than a full-fledged update, as it focuses on optimizations, fixes and improvements. We hope you’ll get to enjoy smoother sailing in Barotrauma over the holidays after these upcoming changes! In Santa’s bag of fixes this year: Optimizations. We’ve made changes to the Farseer Physics engine which Barotrauma uses, as well as optimized rendering. These two should result in a significant performance boost, and there are also various other optimizations coming in the update. Networking improvements. We’ve made various improvements and fixes to address “glitchy” behavior, such as enemies seeming to regenerate health after being shot, characters sometimes teleporting weirdly, or dead bodies hanging from platforms and twitching around. We’re also introducing new fixes to multiple networking errors, such as the "level equality check failed" and "entity event data exceeds the size of the buffer" errors, or the server lobby sometimes appearing empty. Submarine improvements. Reworked the Berilia based on a community submission (thank you WJohnston), visually reworked the Kastrull drone, and fixed waypoints in the Camel. Experience gains improvements. Made XP gains faster especially towards the end of a campaign in various ways, and you can now also adjust XP gain rates in the campaign settings. More: Improvements to the environment visuals, a new optional “toggle run” input which you can bind to a key, and more. Read more about the update now on our blog, and stay tuned for the release next week! P.S. Besides the update, the Barotrauma soundtrack is now available on most streaming services.Hotfix v1.6.19.1 for the Unto the Breach UpdateOct 31, 2024 - Community AnnouncementsHello everyone!

We have just released the first hotfix to address issues that have been found since the Unto the Breach update. Find the list of changes below, and make sure to update your game to the latest version! v1.6.18.1 - Fixed several issues when the server rejects a name change due to a client trying to change their name too often: the server would start spamming the "can't change name" message, team and job preference selection would stop working too, and the game would crash when attempting to open the job preferences. - Fixed equipped genes becoming tainted if you die due to disconnection. - Fixed kill/death counters not working in the Sub vs. Sub PvP missions. - Fixed gravity spheres not rotating in the sub editor. - Fixed current generators not getting properly mirrored in ruins in mirrored levels. - Fixed spawnpoints for escorted characters and prisoners not working. - Fixed crashing if an AI character's husk infection is removed when they're using a ranged weapon. - Fixed psychosis effect persisting if you leave the outpost midway through the "minds unraveled" event. - Fixed night club merchants spawning in outposts without a night club. - Fixed night club merchants not selling beer or rum (literally unplayable). - Fixed bots cleaning up live grenades. - Fixed server getting stuck in an infinite "restart loop" if autorestart or starting when everyone is ready is enabled and the selected perks are not suitable for the selected sub.

Modding: - Fixed outpost generation parameters that reference non-existent NPC prefabs causing a crash during outpost generation.
