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/”

Rocketry Upgrade - Available Now!



Rocketry Upgrade

Since breaking through the surface of the asteroid our Duplicants have developed a curiosity for the endless cosmos that exists outside their little space rock. That’s right, the Duplicants have begun developing their very own space program!

They’re now able to build massive rockets, train as astronauts, and journey on missions into space to bring back the resources they find.

A big thanks to everyone who participated in the testing branch. You’re helping to make the game better and we always appreciate that effort.

What’s New in the Rocketry Upgrade?

Key Features:
  • Rockets: Several new “Rocket Module” buildings for spacecraft construction.
    • Command Module
    • Petroleum Rocket Engine
    • Liquid Fuel Tank
    • Solid, Liquid, Gas, and Biological cargo containers
  • New buildings to support rocket-related research and development
    • Research Telescope
    • Space Cadet Centrifuge
    • Oxylite Refinery
  • A new UI screen for interacting with your fleet of rockets and their missions
    • Five mission destinations
  • A new critter and plant which can be brought back from space
    • Gassy Moo
    • Gas Grass
  • Several new Codex entries to unlock over multiple playthroughs
  • New elements which affect Steel and Natural Gas production
    • Sour Gas

  • A couple new settings for custom games
    • Hunger rate setting
    • Morale stress setting
    • The "No Sweat" game mode preset has been added to help tailor your experience to your preferred playstyle.
What's Next?

We feel the rocketry upgrade content has opened the door to further space industry related content. We’re looking forward to expanding that stage of the game further. We intend to expand the space industry content and systems in the next update.

We’re also getting close to completing the pre-launch features we planned in last year’s roadmap. We feel it’s approaching time to shift our focus to polish, usability, and content backfill. There is plenty of work to be done in those categories.

You can read more about that in this announcement.

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!
