Oxygen Not Included Guides — Keep the Colony Alive

Oxygen Not Included guides and databases built from the wiki: critters, buildings and the life-support loops that keep duplicants breathing.

Where the numbers come from. The tables below are built from the game wiki's own data, not from memory. Where a page needs an exact figure, we mark it and check it before we call it fact.

Sources

Figures and item data on this site are read from the game’s own reference wiki before publishing. Where a value could not be confirmed there, the page says so instead of filling the gap.
