Summary
Hello Subnauts,
As part of our ongoing dedication to the open development process during Early Access, we’re launching the Experimental branch of Subnautica 2 today on Steam.
The Experimental branch is an entirely opt-in experience. It allows players to preview upcoming content for Subnautica 2 in an earlier state, and helps us catch any issues before we ship features to the main Early Access build.
Experimental does often mean just that. The builds are more likely to contain bugs (potentially game-breaking), and we often caution that you not get attached to any saves while playing on this branch.
Saves are also not compatible between versions. This means you can’t import or export saves between Experimental and the main branch. But don’t worry about accidentally loading your saves on the wrong version! Saves are stored in separate locations. This means that while you are playing the Experimental version, you won't see your main saves in the game. But don't worry, if you switch back they should re-appear.
For now, our Experimental branch will not update daily, as it did for Subnautica and Below Zero. Builds will be uploaded to preview our upcoming releases shortly before release to the wider public. We may also use it to preview smaller patches and fixes between major updates.
Interested? Here’s how you can opt in to the Experimental branch.
