The Complete Beginner's Completely Incomplete Guide to Oxygen Not Included


This guide is still a work in progress. A pet project I come back to every now and then. If you have the time, let me know what you think. Was some section difficult to understand? Is there some topic you hope to see added to the guide? That kind of stuff.

You can reach me at somerandomfinn[at] or using the form below.

Guide feedback
Have you been playing Oxygen Not Included for long?



Every now and then someone wonders if the guide is still in development. Which, given that the game mechanics can change with new updates, is a very relevant question.

This guide doesn't include the mechanics or machines introduced in the December 2022 update (Hot Shots). But there haven't been any changes to the game that would have caused the stuff that is in the guide to be misleading or incorrect.


Once I have a complete version of the guide, I'll go over the whole thing and rewrite and tweak as needed. (And I have started adding a few small Hot Shots things already.)

Regarding the "is this still in development" question, I'll keep a tab here of when it was last updated. (Then I just have to remember to update this part...)

  • The guide was last updated in: March, 2023.
