Do you know what you want to build but can't remember what bits go where or what the sensor settings were supposed to be? Check the builds section.

​Hiya, I'm some random Finn. If I told you how many thousands of hours of Oxygen Not Included I have played over the years, you might be tempted to think two things: that I know what I'm doing (I don't), and that I have learned the designs I use often by heart (I haven't).

​​

The resources, guides and builds put together by the community have been a huge help in learning how to piece together an acceptable existence for my dupes. I created this site to give back to that wonderful community. Officially, anyway.

​

​Really, I created this site so I don't have to repeatedly spend hours clicking around in YouTube videos looking for build settings and overlays. (But if anyone asks, tell them the community thing.)

Woooot - I'm a dupe! (Want to be one, too? Talk to Draken:-)
