About Oxygen Not Included
Oxygen Not Included (2019) keeps dupes breathing in an asteroid, opening July 30, 2019 for PC from Klei after early access February 15, 2017. Spaced Out (2021) adds multi asteroids from December 16, 2021. Frosty Planet Pack (2024) adds cold biome from July 18, 2024. Bionic Booster Pack (2024) adds bionic dupes from December 12, 2024. Prehistoric Planet Pack (2025) adds dinos from June 12, 2025. Aquatic Planet Pack (2026) adds ocean start from June 11, 2026.
Each pack stacks on oxygen math without separate story. No new pack has been announced. Play base first, then Spaced Out once you close loops, with planet packs after.
Good to know
Release order matches system order, with Aquatic plumbing assuming atmo basics. Do not enable all packs first, since spaced rockets plus frosty suits overwhelm new bases. The base runs best with No Sweat start before Survival. Treat Aquatic as latest released, with Klei active and no next pack dated.
