How Do I Opt Into the Beta?

  1. Turn off your mods. They will almost certainly cause you to crash.

  2. Go to your Steam library, right click on Stellaris -> Properties -> Betas -> select "stellaris_test - 3.99.4 Open Beta" branch in the Beta Participation dropdown.

All previous 3.99.* Open Beta branches will also remain available. If you are having issues accessing the latest version of the 3.99.* Open Beta, please see this forum post for troubleshooting.

For more information on the Open Beta, as well as the intentions and goals of releasing such an early, unpolished version, please see
this dev diary.

We also have a new feedback survey this week, which looks at first impressions of Precursor selection, Databank, Species Modification, and Game Pacing Adjustments.

This week's Open Beta feedback survey is available here!
