What the developers have to say:

Why Early Access?

“Since 2012, Klei has used Early Access as a tool to gather feedback and build our games in collaboration with our community, producing games like Don’t Starve, Don’t Starve Together and Invisible Inc.. We’ve found this process works for us, and we hope you find it works for you, too.

Our current project, Oxygen Not Included, has already majorly benefited from the feedback provided by players during its Alpha period. By releasing this game in Early Access, we hope to continue to grow our community and get more people involved in its development.”

Approximately how long will this game be in Early Access?

“We still have a lot more in store for Oxygen Not Included, and plan to continue growing and updating the game well into 2018.”

How is the full version planned to differ from the Early Access version?

“The plan for the full version of Oxygen Not Included is to create even more content to allow players to manipulate, automate, and harness the world their Duplicants live in. Duplicants will also become more robust as their needs and abilities evolve over time. To complement this, there will be new biomes to discover, new creatures to interact with, world events to deal with, and more.

We will also be exploring the lore of the game, slowly uncovering the history of the world and why the duplicants are trapped on a giant rock hurtling through space.

Mod support is also very important to us, so we expect to have full workshop support by launch or shortly thereafter.”

What is the current state of the Early Access version?

“Oxygen Not Included currently contains all the core systems that will be evolved and iterated upon during Early Access such as thermodynamics, density, plumbing, stress and hunger. The game has already been played by over 150,000 players in its current state, many of whom report hundreds of hours played. We’re amazed by the breadth and depth of creations that players have made and we’re looking forward to building upon that.”

Will the game be priced differently during and after Early Access?

“The base price may be increased upon release from Early Access.”

How are you planning on involving the Community in your development process?

“We're continually talking to our community about our design process and keeping them informed of our decisions and improvements with regular updates. Please join the discussion on our forums at http://forums.kleientertainment.com/forum/118-oxygen-not-included/”

Oxygen Not Included - Occupational Upgrade Available Now!


In the many weeks since we last saw our Duplicants they've been hard at working being... well, hard at work. They've recently learned that if they work together as a colony and split up their workloads, everyone can get just a little bit faster - and better - at what they do.
...They also re-invented hats.
Introducing: Oxygen Not Included - Occupational Upgrade!

What's New?

Duplicant Jobs
With the new job progression system, your Duplicants will now be able to wear many hats - quite literally! Duplicants can be assigned new jobs in the reworked Jobs Panel, specializing them for chosen tasks within the colony and giving them new perks to boot. Be aware though, Duplicants who work harder may expect nicer amenities to keep them happy, which can mean a heaping helping of stress if you don't plan ahead.
Key Features
  • New Jobs Board: Build a Jobs Board from the Stations Tab to unlock the new Job assignments tree!
  • Revamped Jobs Panel: In addition to the existing function of toggling work errands, the Jobs Panel now contains the Jobs tree, allowing you to assign Duplicants to positions like Miner, Architect, or Engineer, and promote them as they rise through the ranks.
  • New Job Perks: All jobs come with attribute boosts related to their field, but some jobs will also come with work-specific perks that compound as Dupes advance. This means that advancing through the ranks can unlock special skills, like the ability to used advanced machinery or dig through Granite and Abyssalite.
  • Duplicant Job Interests: Everyone in the universe has something they enjoy doing! Assign a Duplicant to a job they're interested in, and their enthusiasm for the work will help them learn to master it just a little bit faster.
  • Hats: Yes, hats. That go on your Duplicants' tiny little heads. These accessories will used to denote which job your Duplicant has been assigned to, and gosh are the Dupes ever excited to wear them.
  • New Stations and Rooms:
    • Farm Station: Enclosing a room and adding a Farm Station will now create a Greenhouse. Duplicants assigned to farming jobs will be able to produce special fertilizer in these rooms and distribute it to nearby crops for a growth boost.
    • Power Control Station: Enclosing a room and adding a Power Control Station will now create a Power Plant. Engineering Duplicants will be able to create upgrade materials in these rooms, allowing them to tinker with nearby generators to increase their power output.
    • Recreation Room: Creating a Recreation Room with a fun building and some decoration will give your Duplicants a place they can hang out and de-stress.
Expanded Automation
Building on existing Automation systems within the game, new buildings and overlays have been added to give you more control over daily colony operations and the breadth of automatable tasks within your base. With the all new Conveyor System, you can deliver ore and solid objects around your colony, put items away in storage, and sweep up floor debris, all without your Duplicants lifting a finger.
Key Features
  • Conveyor Rails, Loader and Receptacle: Found in the Shipping tab of the Build Menu, these new buildings can be used to quickly and automatically transport your materials to construction sites and storage areas. No Duplicant effort required!
  • Auto-Sweeper: This handy automatic machine will suck up and redistribute all the ore and debris in range and shoot it back out into the buildings and storage containers that need it. What a time-saver!
  • New Conveyor Overlay: View your web of conveyor systems and see where materials are headed in your base in real time.
  • Smart Battery and Storage Locker: New Smart Batteries and Lockers can be hooked up to Automation grids and will become Active when they fill up to the amount you specify. That's smart!
  • Smart Fridge: Existing Fridges have been reworked, adding Automation inputs and allowing them to become Active when filled above the specified amount. They also probably know if Dupes sneak in for a midnight snack, and silently judge.
  • Disease Logic Sensor: This Automation sensor will allow you to detect concentrations of Germs and turn systems on or off based on levels of contamination. Automatically lock off a biohazardous area when disease is running rampant, or unleash a flood of Chlorine to flush out a contaminated space.
And More
  • Steam Turbine: Get steamed up for this generator, because it can produce loads of energy with practically no waste!
    • Food and Plant Rebalances: Plants have been tweaked for a more rewarding overall farming experience.
    • Certain plants have received an increase to their calorie output, and have had the ranges of their ideal growth conditions broadened for ease of growth
    • Meal Lice now require fertilization with Dirt
    • Higher tier food production should now be more viable
  • Performance Enhancements!
  • Tons of bug fixes, rebalances, QOL additions, and more!

What about Priorities?
During the Occupational Upgrade's public preview, we experimented with a new priority system. After seeing the changes in all the different scenarios we saw in testing, we weren't happy with the results so we rolled back to the existing priority system. An easier and less fiddly solution to having Duplicants operate your base in the way you want is still an important goal for us, however we believe we can do better so we will tackle this problem in future updates.
Finally, we'd like to say thank-you to everyone who played the Occupational Upgrade Preview, submitted crash and bug reports, and gave your feedback in our Suggestions Forum. It's a major help to hear your thoughts and opinions, so once again - thanks!
We hope you'll all enjoy the new Occupational Upgrade. Now back to work!

[Preview Update] - Hotfix 253538 and a note about priority

Just a quick note regarding priority: in addition to implementing Duplicant Jobs this update, we also tried to tackle some of the thorny issues of Priority. We felt it was a natural fit that Jobs also affect priority, but we haven’t been happy with the side effects. In particular, it was hard to understand, and now that we've added the ability to retain mastery it didn’t make much sense anymore, so we are going to backburner reviewing priorities for a later update.

Please keep posting your feedback, we really appreciate it!
  • Priorities are now 1-9.
  • Jobs now affect priority within a single priority level (e.g. will prefer one prio 5 task over another prio 5 task) rather than across priority levels (6 is always higher than 5 no matter what)
  • Job perks are now permanent upon mastery of the job. The expectations of the highest mastered/assigned job determine the duplicant's expectations
  • Job attribute bonuses adjust to account for permanent perks
  • Jobs can only be changed at the Jobs Desk, construct one to unlock job management
  • A larger number of Duplicants can be assigned to a single job
  • Re-enabled attribute leveling, reduced max attribute base level to 20

  • Add experience gaining and attribute speed bonuses for more chore types
  • Steam turbine should properly stop if entombed or disabled
  • Dupes will now wait for materials to be delivered before digging out any building which affects locomotion including tiles, ladders, fire poles and the pitcher pump. They will however dig out ladders/fire poles without waiting for materials if the job is attached to an existing ladder/fire pole.
  • Liquids will now only sublimate to a max pressure.
  • Conveyor contents should no longer melt when loading a save file.
  • Multiple instances of a building in a room should now be porperly considered inside that room.
  • Fixed a crash that could occur if a door was destroyed the frame after it received a logic signal.
  • Dig damage texture should no longer disappear just before a tile is properly dug out.
  • Fixed an issue where Duplicants would become unselectable.
  • Tiles can no longer be build on top of Tempshift Plates.
  • Duplicant portraits should now be displaying the proper hats in the vitals/consumables screens.
  • Coal Generator is now automatable.
  • Duplicant job progression is now displayed at the bottom of the stats tab.
  • Duplicants with jobs should now properly prioritize the Massage Table if it is the highest set player prioritized building.

About This Game

In the space-colony simulation game Oxygen Not Included you’ll find that scarcities of oxygen, warmth and sustenance are constant threats to your colony's survival. Guide colonists through the perils of subterranean asteroid living and watch as their population grows until they're not simply surviving, but thriving...

Just make sure you don't forget to breathe.

Build Extensive Bases and Discover What it Takes to Survive:


Everything in your space colony is under your control, from excavation and resource allocation right down to plumbing and power systems. Resources will begin depleting with your first breath, however, so be sure to dig fast if you want to live.

It’s Mind Over Matter with Stress Simulations:


Keep the psychological impact of survival at bay with fun leisure activities, great accommodations and even better food for your colony. Duplicants each have different and potentially destructive ways of reacting to stress, so be sure to always keep them happy. Whatever the cost.

Avoid Boiling with Thermodynamics:


Temperature control is a constant concern in space; too cold and you'll freeze, too hot and you'll fry. Keep tabs on ambient environmental temperatures and your colony's heat production to maintain a nice, cozy atmosphere for your colonists.

Enhance Efficiency through Complex Gas and Liquid Simulations:


Create interlocking pipe systems to swiftly deliver fuel and liquid to critical areas of your base. Plan well and be rewarded as your colony transforms into an imperishable, well-oiled machine.

Take Charge with Power Grid Simulations


Choose from a multitude of power sources including coal, hydrogen, natural gas or just plain old elbow grease. Manage power runoff, circuit overloads and meltdowns to keep your colony running smoothly.

Always Keep Yourself Breathing:


Enter the Oxygen Overlay and watch air moving through your base in real time. Monitor carbon dioxide accumulation and oversee oxygen generation processes to mold your colony into a veritable deep-space oasis.

Waste Nothing through Extreme Recycling


Make use of every last resource for a base that truly exemplifies efficiency. Recycle waste into precious fuel, process unbreathable gas into air or harness the natural bodily processes of wild creatures for food. If you’re clever, you might even be able to run a base off colonist farts.

Explore Diverse, Procedurally Generated New Worlds:


Summon new worlds with a push of a button. Experience tons of untamed space rocks, then suffocate to death in them!
