Subnautica Update 84 is now available on Xbox One. Update 84 contains all the content of the Steam version - including rocket bug fixing. Check out the Update 84 blog post to see the full change log.
We are still not ready to formally 'release' Subnautica on Xbox One. We have yet more work to do, particularly with regards to performance and stability. We are taking our time to ensure we release Subnautica properly.
As we work towards a 1.0 Xbox release, we will continue to release updates such as Update 84, which ensure Xbox players have all the features, bug-fixes, and gameplay that Steam players enjoy.
