**The Aquatic Planet Pack **plunges colonies into the deep end of a marine world of kelp forests and coral reefs, where expanded aquatic ranches cater to cuisine and construction projects alike, and clams grow bigger than Duplicants. There are brand-new biomes, plants, resources, foods and buildings, plus two new recruits—including one who's unnaturally well-adapted to the environment. (And needs to be convinced to join you.) Don't miss the exclusive collection of cosmetic blueprints that helps colonies present a nautical facade, even if they haven't quite found their sea legs yet! Explore underwater ecosystems that unleash new possibilities for power systems, and master the art of keeping your colony's head above water when dry land is as scarce as Duplicant brain cells. (It's okay, their crewmates know CPR.) Whet your appetite for this wet new world with the [new short here](https://www.youtube.com/watch?v=dnGEHeStgZo)! **The Aquatic Planet Pack **can be purchased for 9.99USD and is available now on Steam, WeGame and Epic.

For this free update, we focused on squashing a bunch of bugs. We also made some changes to the sim and upgraded the version of the Unity engine we use. Everything mentioned in this post applies to all versions of ONI. ##### **Highlights** - Upgraded Unity - Modified the temperature exchange formula to be less error-prone. - Small masses (micrograms) now exchange temperature in the sim. - Fixed a number of bugs with off-gassing liquids. - Domesticated plants no longer consume fertilizer while wilted. - Hidden fog of war tiles associated with POIs will now be correctly revealed. This will not fix existing saves. - Fixed open doors transferring temperature in a vacuum. - Batteries no longer function when entombed. ##### **A little more detail...** We tweaked the formula we use for temperature exchange for tiles and debris, making it more stable for small fluctuations and oscillations. It should feel the same, just less buggy! We've also added temperature exchange for small masses, which should clear up the issues folks were experiencing when using the Conveyor Rail Element Sensor to separate out cooled elements from hot ones. Off-gassing liquids that were emitting gases in the wrong amount or at the wrong temperature, removing more liquid than intended, and/or deleting mass from the tile below them... will no longer do that! Whew. Ugly Criers now produce the expected volume of tears. Previously, some tears were evaporating instantly because they didn't have enough mass. Now, Dupes will hold back their tears until they've got enough mass built up to properly open the floodgates of emotion. Meanwhile, Duplicants who share the same name will no longer mistakenly share the logging of their stress modifiers in UI screens. Open doors will no longer cause temperature to be exchanged in a vacuum. This resolves issues where open mechanized airlocks could erroneously transfer heat, and should also resolve instances of gases not flowing through open doors. In new games, POIs that are hidden behind fog of war will now be revealed correctly. ##### **Summary** We took a break from paid DLCs to fix bugs! Hopefully, this helps everyone's colonies chug along more smoothly - surviving in space is challenging enough already. Found new bugs? [Report 'em here](https://forums.kleientertainment.com/klei-bug-tracker/oni/). Got feedback? [Let us know here](https://forums.kleientertainment.com/forums/forum/133-oxygen-not-included-suggestions-and-feedback/)! Your insights are super valuable to us. Thank you so much for playing! ##### **Full patch notes** **Changes and Improvements** - **All versions** - Upgraded to Unity 6.3. - Made adjustments to the Printing Pod sidescreen UI Layout and added a Research button. **Fixes** - **All versions** - Simulation - Removed lower mass limit for temperature exchange in the sim for tiles and debris. - Tweaked the formula we use for temperature exchange for tiles and debris, making it more stable for small fluctuations and oscillations - Fixed a bug where material that didn't exchange temperature would not consider changing state. - Fixed bugs where off-gassing liquids in the sim could emit the wrong amount of gas, emit it at the wrong temperature, remove more liquid than was intended, and/or delete mass from the tile below them. - Batteries no longer function when entombed. - Percentages displayed in the UI no longer round up to 100%, to avoid confusion in cases where the real number is actually slightly lower (e.g. 99.6%). - Domesticated plants no longer consume fertilizer while wilted. - Nosh Beans, Sleet Wheat Grain, and Mimillet will now rot while marked for compost, and retain their rot value if the compost request is cancelled. - Adjusted mouse drag threshold before a click is interpreted as a drag, to reduce mislicks on buttons. - Hidden fog of war tiles associated with POIs will now be correctly revealed.

We're releasing the **November 2025 Quality of Life update** today! This free update features performance improvements for all versions of ONI, polished-up QoL for old systems, new critter morphs, a bioprinter story trait, cosmetic blueprints, and more. ##### **Highlights** - Critter morphs: Husky Moo, Blum Lumb (The Prehistoric Planet Pack), Shatter Flox (The Frosty Planet Pack) - Story trait: Printerceptor - New elements: Plant Husk, Plywood - New buildings: Plywood Press, Communal Table, Insulated Door, Display Shelf, Biodiesel Engine, Wicker Door (The Frosty Planet Pack), Research Module (Spaced Out! DLC) - New room: Banquet Hall - Performance improvements ##### **QoL improvements (all versions)** We've rebuilt and tweaked things behind the scenes to help us make lots of improvements that add up to a better overall experience. For example, pathfinding is faster, Jet Suits have better tuning and animations, and critters now calculate how crowded or cramped they feel based on their own individual space allocations. That makes it easier to manage ranches that contain multiple species. It's also easier to find what you're looking for in the build menu: hitting CTRL+F on your keyboard pulls up the build menu and focuses on its search bar! ##### **New buildings & elements (all versions)** Skilled farmers can now salvage a new Plant Husk byproduct when they're harvesting certain plants. Feed it to Gassy Moos to increase their chances of calling a biodiesel-producing Husky Moo to your planetoid, or combine it with Resin at the new Plywood Press to produce the new Plywood building material. Duplicants can dine with friends at the Communal Table in the morale-boosting Banquet Hall room, show off artifacts and keepsakes on a Display Shelf, keep spaces thermally regulated with the Insulated Door, and more! ##### **Story trait: Printerceptor (all versions)** Uncover the Printerceptor, a new bioprinter building! It processes Data Banks and draws power from the Printing Pod to print a selection of very useful items on demand. There's just one catch: you'll need to unlock it first, using a code that is buried...somewhere on the planetoid. Better start digging! **Spaced Out! DLC** Mining space resources and gathering them can now be done separately! Once resources have been mined with a Drillcone, they'll linger at that site as free-floating harvestables until they're gathered by a rocket with a resource-appropriate cargo module. (For example, artifacts require an Artifact Transport Module.) Space POIs start with free-floating resources available, and the new Research Module allows rockets to collect any Data Banks found there. We've also made it easier to produce and store Radbolts, which is pretty rad! **The Bionic Booster Pack** There's a new two-tier Skill branch for Bionic Duplicants: Improved Hardware, which makes them immune to eye irritation and popped eardrums, and Climate Control, which makes them immune to the effects of chilly and toasty surroundings. (They can still get scalded or frostbitten though, so be nice!) **The Frosty Planet Pack** Floxes raised in super high-decor areas have a chance of producing Shatter Flox morphs, whose dazzling antlers can be shorn for glass. Using Wood as a building material now boosts the finished product's Decor value, and we also added a breezy new wooden Wicker Door. **The Prehistoric Planet Pack** Ranching your Lumbs in a CO2-infused space increases their chances of laying Blum Lumb eggs, which will grow into stompy green morphs that produce algae. Over in the Supply Closet, there's a new Higby monument top to celebrate our beloved mustachioed crewmate. **New cosmetic blueprints** You'll find over 100 new blueprints in the Supply Closet! If you own a DLC that has a themed Printing Pod blueprint, you'll find the new matching Mini-Pod in there too. ##### **New Animated Short: Hangry For More** When rations run low, tensions run high! A very hangry Hass _[Truncated at 4000 characters — full notes: https://store.steampowered.com/news/app/457140/view/600795607306601383]_ ### [Game Update] - 693461 - Date: 2025-10-08 - Original notes: https://store.steampowered.com/news/app/457140/view/546748595947176030 - Permalink: https://whatsnew.fyi/product/oxygen-not-included/releases/steam-546748595947176030 **All Versions ** - Integrated Unity Engine security update to address recently reported vulnerability. ### [Game Update] - 679336 - Date: 2025-07-18 - Original notes: https://store.steampowered.com/news/app/457140/view/546741075848462516 - Permalink: https://whatsnew.fyi/product/oxygen-not-included/releases/steam-546741075848462516 **Changes and Improvements** - **Prehistoric Planet Pack** - Added a new Higby-themed monument top blueprint to the Supply Closet. **Fixes** - **All versions** - Potential fix for a crash that can occur after deconstructing the Fish Release. - Fixed an issue where the shearable product of large critters sometimes spawned entombed inside of natural tiles instead of next to them. - **Spaced Out!** - Restored radbolt cost display UI to fabricator recipe side screen. - **Prehistoric Planet Pack** - Fixed an issue causing Rhex-themed monument top blueprint to sometimes display incorrectly. ### [Game Update] - 678383 - Date: 2025-07-10 - Original notes: https://store.steampowered.com/news/app/457140/view/503956335787769861 - Permalink: https://whatsnew.fyi/product/oxygen-not-included/releases/steam-503956335787769861 **Changes and Improvements** - **All versions** - Updated Korean localizations. **Fixes** - **All versions** - Fixed Critter Pick-Up and Critter Drop-Off displaying different critter counts in the same room. - Fixed an issue with Pips rummaging seeds from Storage Bins causing the seeds to float and be inaccessible. - Fixed buildings not displaying light rays correctly. - **Spaced Out! only** - Fixed issue with Payload Opener and Supply Teleporter Output shipping liquids and gasses as bottles. - **Prehistoric Planet Pack** - Fixed crash when destroying Demolior in the base game due to debris finding no place to spawn. ### [Game Update] - 677228 - Date: 2025-07-02 - Original notes: https://store.steampowered.com/news/app/457140/view/546739082808528011 - Permalink: https://whatsnew.fyi/product/oxygen-not-included/releases/steam-546739082808528011 **Changes and Improvements** - **All versions** - Pokeshell molt pickupables now change their visuals depending on their mass. - Database search now also searches entry titles and categories for a match.
