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...

Deep inside an alien space rock, your industrious Duplicant crew will need to master science, overcome strange new lifeforms, and harness incredible space tech to survive, and possibly, thrive.

You'll need water, warmth, food, and oxygen to keep them alive, and even more than that to keep them happy.

Klei is happy to announce the full release of the resource management sim, Oxygen Not Included, which will be leaving Steam Early Access on May 28.

Jamie Cheng, founder of Klei Entertainment said: “After two years, we are happy to announce that Oxygen Not Included is coming out of Early Access on May 28. Throughout Early Access, we’ve added a ton of content, polish, improvements, optimizations and features to realize our vision of the game. Features such as simulating disease, implementing a skill system, adding creature taming, logic gates, automation, duplicant scheduling, recreational facilities, as well as a menagerie of new creatures, biomes, official mod support, space travel, and more, have all been added to complete the experience.

“We have sold almost two million copies so far and we’ve been amazed at how the community has taken the game and run with it, including AC/DC's "Thunderstruck" built with logic gates, a 100-Duplicant challenge colony, and an astonishing retrospective of a 2000-cycle colony. It is all so much more than we could have hoped for and we’re so grateful for our community’s continued feedback and support.”

With the final Oxygen Not Included Early Access update Klei is introducing a host of new features, including three new biomes, new buildings, new creatures, and asteroid generation settings, so each playthrough can feel fresh and challenging.

To celebrate the launch of Oxygen Not Included on May 28, the Early Access on Steam will be available for 25% off, from April 16-18.

Key Features:

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