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/”

Automation Upgrade Available Now




[T H I S I S A N A U T O M A T E D M E S S A G E]

Hello [USER], and welcome to the Automation Upgrade!

Our Duplicants have been hard at working researching new and wonderful technologies in the depths of their cosmic prison, and happily to say, they've come up with a brand new system of base management: [AUTOMATION]! So relax, take a load off, and let the machines do the work!

What All's New?

Automation

A brand new collection of automation-based items have been introduced into Oxygen Not Included, allowing you to wield Boolean logic to run your base at absolute peak efficiency. Logic sensors, switches, and gates are among a few of the items you can now use to turn your base into a literal well-oiled machine.
Key Features
  • Logic Gates: AND, OR, XOR, NOT, Buffer, and Filter gates are now available for devising and building you own logic circuitry in your base.
    Sensors and Shutoffs:
    • Thermo, Atmo and Liquid Sensors: Detect ambient air pressure, temperature, and liquid pressure with these sensors to turn your machines on and off. Construct built-in safeguards against overheating and high pressures, or just turn your machines off automatically when they're no longer needed.
    • Clock Sensor: Duplicants crave structure! Start scheduling your Duplicants' day cycles with these clock sensors, allowing you to determine the exact time of day your systems should turn on and off. You could even turn out the lights when it's time for the colony go to bed.
    • Weight Plate: Trigger your automation grids when creatures, ore, or Duplicants press down on these new floor switches.
    • Signal Switch: Automation just doesn't feel right without a human touch - or a Duplicant one at least. Use these manual switches to input Active or Standby signals into automated systems at your leisure.
    • Liquid, Gas, and Power Shutoffs: Use automation to precisely control when and where precious resources flow in your base.
  • Duplicant Checkpoints: Combine these doors with other switches and sensors and you can control exactly when and where Duplicants are allowed to travel. Prevent Dupes from entering dangerous environments, or signal them to travel to remote areas only when valuable resources are available.
  • New Building Inputs: Automation ports have been retroactively added to all existing compatible buildings, meaning they're ready and waiting to be automized!
  • Automation Overlay: Enter the Automation Overlay to see your new circuitry in all its glory.
Refinement
A new mid-tier family of construction materials has been added between raw resources and plastics, allowing you to use refining techniques to purifying your metals into more efficient refined metals. These refined metals can be used to construct new buildings, or to create improved versions of existing buildings, such as wires and tiles to upgrade your infrastructure colonywide.
Key Features
  • Rock Granulator: Crushing down raw minerals with this Granulator allows you to renewably produce sand, and yields you a bit of refined metal as well!
  • Metal Refinery: New metal refineries allow to efficiently process refined metals in bulk, but be warned - the runoff can get a bit toasty.
  • Metal Wires: New wire types such as Conductive Wire and Heavi Conductive Wire have been added using new refined metals, improving wattage handling and decor.
  • Metal Tiles: These tiles majorly improve decor and transfer heat quickly through your base.
And More
  • Fire Poles: Got somewhere you need to go, fast? These fire poles are the answer! ...Unless you're trying to climb back up, that is.
  • Aerial Creature Lures: This attractive device can lure those pesky flying creatures that until now have evaded all your traps. Set it with some bait and those Pufts and Shinebugs won't be able to resist!
  • Mini Gas and Liquid Pumps: Cute, tiny little pumps are now available to build for those situations where a regular pump is just too much. They're both power efficient, too!
  • Tempshift Plates: Slow down or accelerate the rate of heat transfer in certain areas using new Tempshift wall plates. Their efficacy depends on the type of material you use to build them, so choose wisely!
  • New Ruins Setpieces: What new things are hiding within your world, waiting to be discovered? You'll need to explore to find out!
  • Tons of bug fixes, rebalances, QOL additions, and more!
Tweaks
  • Existing sensors and some switches have been reworked as automation buildings and can no longer be connected directly to power grids.
  • Oil and other hydrocarbons have new solid states, and will now freeze when reaching low enough temperatures.
  • The Research Tree has been expanded and revised to include new buildings and improve the experience of researching new technologies.
  • Finally, we'd like to give a big thank-you to everyone who participated in the Automation Upgrade Preview - as always, your reports, feedback, and contributions have been especially helpful in developing new content for this upgrade.
    Thank-you and enjoy the Automation Upgrade, [USER]!

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!
