About Oxygen Not Included

Oxygen Not Included is a space-colony simulation where the very essentials of life, oxygen, warmth, and sustenance, are always in short supply and pose constant threats to your colony's survival. Your job is to guide colonists through the perils of living deep inside a subterranean asteroid, keeping them alive against the relentless scarcities pressing in from every direction.

The goal reaches beyond mere survival. You work to grow your population and develop your colony to the point where its inhabitants aren't just scraping by but genuinely thriving, transforming a hostile rock into a functioning home. Getting there means carefully juggling resources and systems so that breathable air, heat, and food never run dry.

Of course, amid all the complex management, the game reminds you not to forget the most basic thing of all: keep breathing. Blending indie sensibilities with deep simulation on PC, Oxygen Not Included turns the challenge of sustaining life underground into an intricate balancing act where every overlooked detail can jeopardize the whole colony.
