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 bit more in store for Oxygen Not Included, and we plan to exit early access some time in this year.”

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 1,500,000 players, 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/”

QoL Upgrade Mk 2 Now Open For Testing!

Originally posted on the official forums by Ipsquiggle

Hello astro-friends!

The Quality of Life Upgrades continue to roll out as our team scours their bug lists and reviews all the feedback you've given us here in the forums! We're also still working hard to improve game performance and systems.

A high level of focus in QoL Mk 2 has been directed toward adding tools to help you understand what work your Duplicants are doing around the base and how they're moving through it. We've also added in Space Artifacts for you to display on your Pedestals, and some exciting new upgrades to the Printing Pod's capabilities. And of course, we've knocked out all kinds of bugs and crashes thanks to your reports!

For those who missed it in the previous Upgrade: A public Testing Branch for this Upgrade will once again be available as they have been in the past, with the change that testing periods will now run for 3 weeks instead of the regular 2. Our intention is to provide additional time for your feedback to be heard before these changes go out to the world. (Please note that the Testing Branch will continue to have additional crash reporting enabled and will impact your game’s running performance. Finalized performance improvements won't be noticeable until the Upgrade releases to everyone.)

We look forward to reading your thoughts and opinions on the Suggestions Forum.

Thank-you!

This update is absolutely massive - for more details and update notes, head on over to the official forums.

Quality of Life Upgrade Mk 1 Available Now!



Hello intrepid colony managers!

Today we're happy to bring you the first edition of our new "Quality of Life" Upgrade series! This series will differ slightly from Upgrades we've released in the past, as we shift our focus toward a new stage of development dedicated to evaluating all game content to date. This means looking at improving performance, filling in remaining holes in content, and rebalancing existing systems (hooray!).

The intent of QoL Mk 1 is to begin working through the important issues that have been brought up by users on our forums (thank-you for your feedback and reports!), as well as eliminating major game-impacting bugs, and improving the quality of Oxygen Not Included's early game for new users. As a result, QoL Mk 1 introduces new recipe queuing UI options, more building copy settings, and a bunch of new content expanding the decor system such as varieties on existing paintings, sculptures and flower pots (plus a whole assortment of crash fixes and performance tweaks).

Throughout the rest of the QoL Upgrades, we will be continuing to monitor the forums and your reports for more feedback on how we can improve the game. We've made some serious progress on bugs and polish this update, but there's still more to come! We've still got even more systems to balance and optimization to perform.

In addition, the team will be taking a two week break over the holidays and getting back to it in the New Year. The next update will be on schedule in 8 weeks, coming out February 7th.

Thank you to everyone who participating in our open testing branch, we hope you enjoy the decor!

What's New and Improved?
The majority of the work this Upgrade has been on a wide range of bugs and tuning, so rather than a list of high-level features like we usually do, here's a massive categorized list of the changes and improvements we've made.

New Things
  • New Pedestal Building: Use it to increase the decor value of various objects while displaying them for your Duplicants
  • New Artifact Objects: Bring them back from outer space for decorative display in your colony
  • New Decor Items: Corner Decorations, Carpeted Tile, Trim Tile, new Painting and Statue variations, new Pot types for plants
  • New Master Artist role: Allows the creation of the best forms of art (and the Astronaut role finally has its own hat too!)
  • Increased Automation: Critter Sensor outputs a signal based on the number of critters and eggs in a room
  • New Sight-Seeing Module: Send Duplicants to space for a huge morale and productivity bonus

And A LOT more

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!
