What is open testing?

"Open testing" means players get to test-drive new content early and give us feedback and suggestions before it goes live. Because this is an unfinished and in active development version of the game, it's pretty likely you'll encounter bugs, crashes or balance issues while playing these builds. We'll try to fix any problems that crop up as quickly as we can, but it's possible you'll lose progress in your games while playing on the Testing branch.

Regarding performance, the Testing branch has additional debugging tools enabled to help us track down crashes. This makes the game run more slowly than the live version of the game.

Please also be aware that once a save is loaded in the Testing branch, it cannot be reopened again in the previous Live branch or previous builds.

What do I do if I find a crash or a bug?

Post it up on the Bug Tracker and we'll fix it as soon as we can. If you can attach a copy of your save file to your report, that helps us even more as we can pinpoint the source of problem more quickly.

Do I have to play the open testing build?

Nope! If you'd prefer to only play a stable build, you can continue to play in the current Default branch until the game launches in full. Playing the Open Testing build isn't necessary, but it helps us a lot to receive your feedback and reports - if you're interested, try it out!

How do I become an open tester?

There's no sign up or registration for becoming an open tester. If you own Oxygen Not Included and want to join the Testing Branch, all you have to do is play the Open Testing build on Steam.
