Oxygen Not Included — complete walkthrough & base layout
From first duplicant to a stable, cooled, self-feeding colony: progression order, the mistakes that end runs, and a base that survives past cycle 200.
Walkthroughs · Progression lists · Build guides
Text-first guides for the games that eat your evenings. Materials, quantities and coordinates you can build from — not a video you have to scrub through.
Each game gets its own hub: walkthroughs first, then progression lists, build guides and reference layouts.
If you are new to a game, these are the ones to read first.
From first duplicant to a stable, cooled, self-feeding colony: progression order, the mistakes that end runs, and a base that survives past cycle 200.
Room layout, race choice, food and mood management, and the order that stops your first settlement collapsing.
What to build in the first days, how to survive the first raid, and the point where a colony usually dies.
Everything on the site, newest first.
Every guide is played through and checked before it is published. Nothing here is paywalled, and there is no account to make.
