On Xbox, the Experimental branch is available through the Xbox Insider Program, using the Xbox Insider Hub app:
1. Install the Xbox Insider Hub app from the Store (free) on your Xbox console or PC, if you don't already have it.
2. Launch the app and sign in with your account.
3. Go to Previews.
4. Select Subnautica 2 Experimental (Public Test) and click Join.
5. Wait for the registration to complete, then follow the prompt to install. You may need to restart your console to trigger the update.
Once installed, you'll be playing on the Experimental branch. To leave, open the Xbox Insider Hub, select Subnautica 2, and leave the preview — you'll then re-download the default build.
