If you don't want to play Satisfactory on the latest public version, and would rather play a different beta branch such as experimental to playtest upcoming updates, here's how to change the version of your Satisfactory server.

Danger

Features from experimental versions are not expected to be supported on shared hosting as this is only a testing ground for the game developers. As this deletes everything, download a backup to your PC first if you want to keep your save. We officially only support the main, public branch of the game.

Changing Steam Beta Version

1
Log in to Bropanel and Stop your server.
2
In the sidebar, go to Settings.
3
Edit Steam Beta Branch.
4
Click Reinstall in the top-right.
5
Select Format (keep settings), then confirm and wait for the install to finish.

Here are the currently available beta branches to choose from, they can be found here:

Satisfactory Beta Branches.

The main branches are public and experimental.
