[Game Update] - 469287

Release Date: 06/24/21

Update Information:


Hello friends!

Today we present The Big Merge Update: A highly technical squishing of the Base Game and Spaced Out! codebases. This means that Spaced Out! owners can toggle the DLC on-and-off from the main menu with a simple restart of the game. Playing the Base Game in this way will  give you all the bug fixes and quality improvements that we've added to Spaced Out! since we went into early access, while still allowing you to enjoy the game-play of the original ONI you know and love.

(These changes will be coming to the Base Game for all ONI players in the next few updates, but we're limiting them to Spaced Out! owners to make sure they get proper testing for now.)

What we're working on here is the continuing evolution of Oxygen Not Included. While our attention has been mostly on the DLC lately, our desire has always been to improve and evolve the game as a whole. There are a number of changes that we've made in Spaced Out! which are just intrinsically good improvements to the game, some we had planned for the Base Game all along but finally got the opportunity to implement during Spaced Out! development.

This includes the many bug fixes and minor improvements we've made during Spaced Out's development, including fixing several major simulation bugs and countless typos. It also means modding should be simplified because there is only one version of the game to mod against.

Speaking of modding... We have a doozy of a modding update! Modders, please read Updating to Harmony 2.0. To all players: these significant technical changes are going to result in many mods needing updating in order to work. Please be kind to the modding community and give them time to react to the new code.

This patch also includes updating our development to the next major version of the Unity engine. While this has little impact on what you see as a player, it's necessary for us to continue supporting the game and pushing development forward.

These are the features that you've seen in Spaced Out! which are now going to be part of the Base Game:

  • New traits, including skill-granting traits
  • Some shuffling of the tech tree, notably moving most of the Conveyor Rails techs one tier earlier
  • Updated food storage/refrigeration mechanics will be the same in both versions of the game
  • Meter Valves are now in the Base Game
  • Oxygen Masks are now in the Base Game
  • Suit durability mechanics will be available in the Base Game (but toggled off in the game settings by default)
  • "Stinging eyes" and related debuffs which give all players more reason to be cautious with chlorine
  • The Diagnostics panel, updated Resource screen, and other UI improvements will be consistent for all versions of the game
  • Demolition skill will be available for everyone!

All other new content (in particular the new rockets and multi-asteroid starmap, and radiation buildings and overlay) will remain in Spaced Out! only.

Spaced Out! owners are now able to try this new version of the Base Game - just launch the game as usual and use the button in the main menu to toggle the DLC off. (You'll know it worked if your build number starts with "MD")

Thanks for sticking with us through this large technical challenge. If you notice anything that seems to be amiss between the two versions of the game, please report it as a bug! And as always, we'd love to hear any other feedback you have. Take care!

  • Fixed issue with lead suits where dupes would not rush to return suit if the lead suit tank was almost empty but the oxygen tank was still full
  • Updated title text for the update image in the main menu
  • Corrected capitalization of kilogram
  • Fixed issue where buildings did not refresh their skill-required operations when Duplicants were teleported between worlds
  • Clicking on the Skills button no longer crashes the game after a Spacefarer Module has been deconstructed
  • Fixed crash that could occur when collecting space artifacts with multiple Artifact Transport Modules on the rocket
  • Space POI resources are now discovered when mined allowing them to be unloaded using rocket ports

  • Made several more Gravitas objects demolishable
  • Fixed typo in Landing Beacon description
  • Fixed various typos of Beetas and Plug Slugs
  • Dragging the order of mods on the mods screen no longer sends mods to the bottom of the list randomly. Drop position is now also calculated "between" mod entries so it's easier to change the order intentionally
  • Fixed layering issue with Telescope when a Duplicant is using it
  • Fixed crash when deconstructing Small Gas Cargo Module.
  • Fixed Gassy Mooteor anim hitch on impact

  • Improved performance of opening the Load Game screen by 50%

  • Fixed a performance issue with the Entombed Buildings Diagnostic


  • Mod uploader now shows an error if any common game data is in a mod upload package
  • Mod uploader allows selecting whether your mod is compatible with Base Game and Spaced Out!
  • DLL Mods will need to be updated to continue working with the game. Please read this post for full details.
  • New UserMod2 class: inherit from this class in your mods to use the new modding functionality
  • The UserMod2 class now has a `mod` property on it which will contain a reference to the Mod this assembly is being loaded by
  • mod_info.yaml has a new optional field `version`, a string that gets prepended with a 'v' in the UI
  • mod_info.yaml has a new field `APIVersion`. If a mod loads a DLL, this must be set to `2` to indicate that the latest version of the mod system (i.e. Harmony2.0) is being used, otherwise the mod will be disabled
  • mods.yaml has a new optional field `staticID`. If provided, this will be stored on the Mod object for reference, as well as used as the ID provided to Harmony. This can be used to more reliably detect when other mods are installed, regardless of how they were installed.
  • The Mod class now has a field `packagedModInfo` which contains the mod_info.yaml from the loaded version of that mod
  • `lastWorkingBuild` has been replaced by `minimumSupportedBuild` in mod_info.yaml. The behaviour is now: "From the mod archives with supported content, pick the one with the highest supported build that doesn't exceed the game build."
    • When you update a mod for testing branch, just put the existing version in an archive folder, and make your preview version have the preview build as the minimumSupportedBuild
    • This change is also being made to the non-Spaced Out! version of the game, for forward compatibility



Fixes since the last preview build

  • Fixed crash when switching between worlds while viewing the out of bounds area above the surface.
  • Worldgen: Teleporter world of the Spaced Out Forest and Swamp clusters height was incorrect. Now it's the same size as the one in the Spaced Out Terra cluster.
