Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

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/”

Expressive Upgrade - Available Now!



Though originally thrown together by cruel cosmic circumstance, the Duplicants of the colony have weathered incredible hardships together and come out the other side as stronger friends for it. Armed with their new talents of self awareness, compassion and extreme friendliness, our intrepid Dupes are now fully committed to supporting each other through life in the colony - the good times, and the bad. 

But mostly they'll just chat about cute Hatches.

What's New in the Expressive Upgrade?

Duplicant Interactions

Duplicants have new powers of self expression and are now more aware of the colony, themselves, and even their peers. New animations, expressions, and interactions have been added to help the Duplicants convey what's happening to and around them.

Key Features
  • Reaction Animations: Duplicants will now visibly react when they gain new status effects and notice when important things happen around them.
  • Interactions: Duplicants will greet their friends in the halls, chat a bit while working, and compliment each other on a job well done. Turns out they're not alone on this asteroid!
  • Conversations: Do you like Mushbars? I like Mushbars! Mushbars are pretty good. You're such a good listener, you know?
Scheduling and Personal Time

As part of their new self-awareness, Duplicants have become concerned about about their Morale. Just because they're buried under miles of rock and slime (and half of them have embarrassing GI problems) doesn't mean they can't be happy!

Key Features
  • Scheduling: Colonywide schedules can now be adjusted, not only to give the Duplicants much needed Downtime at the end of the day to socialize and unwind, but also to ensure they empty their bladders before they run off to work!
  • New Recreation Buildings: While the most basic of breaks can be accomplished by hanging out by the Water Cooler, Duplicants can really let loose at the local Jukebot or Arcade Cabinet!
  • Morale Expectation: Job expectations have been unified into a single Morale rating, which encompasses Duplicants' food, lodgings, activities, and whatever else on the asteroid that they find fulfilling.
And More!
  • New Mini Transformer: A new Mini Transformer has been introduced to improve technological progression through the Research Tree. Pick up the mini version for a quick start into Transformer usage, then build the full Transformer for a real challenge!
  • Discoverable Lore Entries: What was "Gravitas", and what was their purpose? How did the Duplicants end up on the asteroid? Inspect buildings, critters, and more to fill your Database and start unraveling the mystery!
  • Completed Animations and Sounds: The rest of the Critter animations, including babies, wrangling, and morphs have been completed, along with a number of buildings which previously had been silent.
  • Tons of bug fixes, rebalances, QOL additions, and more!
We'd like to thank everyone who participated in the Expressive Upgrade Test Branch, submitted your crash and bug reports, and gave your feedback in our Suggestions Forum. We're always grateful to hear your thoughts and thank you for the time spent playing our game.

Now go take a break!

[Game Update] - 273433 - Cosmic Upgrade


"Space" just got bigger--literally. Miner Duplicants have broken through the crust of the asteroid, revealing the entire big ol' cosmos beyond! This stellar discovery has spurred new material innovations as the Duplicants rush to exploit the frontier while defending themselves from the uncaring vacuum (and unsightly freezer burn) of space.

The truth is out there!

What's New in the Cosmic Upgrade?

Space Biome

"Look at me, Liam! I'm on top of the world!" The surface of the asteroid is a source of abundant natural resources along with new hazards for your Duplicants to navigate.

Key Features
  • Solar Light: The abundant energy of a nearby star can be harnessed for electricity with Solar Panels. Your poor cave-dwelling Duplicants will appreciate the warm natural light as well, provided they don't roast!
  • Meteor Showers: The good news: free resources! The bad news: they're traveling at 16 kilometers per second. Protect your surface infrastructure with meteor-proof walls and shutters, along with the new Meteor Detector.
  • New Elements: Improved material science has enabled the production of Steel, Ceramics, Glass, and other basic materials.
  • Windows and Walls: Now your Duplicants can build a room with a view. Transparent windows allow light and decor to pass through, while keeping your precious gasses and liquids right where you want them. Back walls offer protection against the greedy vacuum of space for those who dare to build on the surface.
Critter Additions

Like a swarm of Shine Bugs, the ranching opportunities continue to expand with new buildings and improvements.

Key Features

  • Updated Egg Economy: An Egg Cracker building makes planning your next omelet as easy as pie, which is a good thing because eggs have undergone some mass changes, as well as becoming unviable if left in storage for too long.
  • Updated Critter Artwork: Completed eggs, babies, wrangled, and trapped artwork for all critters. Hooray!
  • Automated Pen Management: Before, your Duplicants merely kept critters. Now, they're ranching them! Pen limits, as well as automatic wrangling and transfer, lets you build the coal-producing machine of your dreams.
And More!

  • Powered Door Finally Powered: It's nice and zippy when it's plugged in, but make sure you've got enough batteries charged to keep it working!
  • Power Production Rebalance: With the addition of solar power, numerous tweaks have been made to the electricity economy.
  • Performance Enhancements!
  • Tons of bug fixes, rebalances, QOL additions, and more!
We'd like to thank everyone who participated in the Cosmic Upgrade Test Branch, submitted your crash and bug reports, and gave your feedback in our Suggestions Forum. We're always grateful to hear your thoughts and thank you for the time spent playing our game.

Enjoy your time in space!

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!
