Oxygen Not Included Has Launched!! - [Updated w/ Hotfix 361684 8/22/19]


Originally posted by Ipsquiggle on the official forums.

Today is the day!

The fridges are full and the toilets are empty, the pipes are plumbed and the power’s been generated… plus there's hardly any pee on the floor at all! That can only mean one thing; the time has finally come to open the bunker doors and invite everyone in to see the glorious machine we’ve created!

Oxygen Not Included has officially left Early Access, and we're ready to let everyone come see what we've been working on these last 5 years!

So what have we been working on all this time, anyway?

Oxygen Not Included is a space colony simulation game where you oversee your Duplicants (aka, lovable 3D printed clones) as they attempt to overcome the harsh conditions of deep space. Master advanced science and technology, capture and tame strange new lifeforms, and plan your base with expert efficiency so that you and your colony may survive… and even, possibly, thrive.

The game has come a long way since it went into Alpha in February 2017. We started with a game that had little more than a few Duplicants and some pipes full of cold water. Since then we’ve added oil biomes and automation, Duplicant skill progression and tubes to zip around in, critter ranching and breeding, and more features than could possibly be named. Now Duplicants can even break through the surface of their rocky home and escape away into space… with your guidance, of course.

The adventure’s not over yet, either. We'll continue fixing bugs and balance after launch, so please keep sending your feedback and reports! We also have more we want to do with the game in the future, so keep an eye out for announcements.

It's been an intense but delightful ride and we couldn't have gotten here without the support of all of you from this awesome community. The whole team would like to thank you for your comments and support, your bug reports and your discussions, your insane machines and your beautiful stories.

Please, enjoy Oxygen Not Included! This Mushbar's on me.

Oxygen Not Included Launching July 30th!



Originally posted on the official forums.

Hello friends!

Next week, July 30, Oxygen Not Included will be launching out of Early Access! Here is a brief list of the things we've added for launch, a full list will be available on launch day.
  • New asteroids to explore, with their own rolled traits
  • Three new biomes complete with plants and critters
  • New buildings to process and upgrade the materials you'll find there
  • Colony goals for the duplicants to strive for
  • Balance and polish passes on food, temperature, Duplicant selection, and more
For us, launch means that the main features of the game are complete and we feel the general public can enjoy the game. Rest assured, we will continue to be working on the game post-launch. After July 30, we will continue with bug fixes and balance changes; we also have more content we want to explore with the game in the future, and we will let people know more about our plans when the time comes.

Thank you everyone for staying with us the past two years, and I look forward to continuing the journey with you!

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!
