This news has gone totally under the radar over the past 24 hours, with no patch notes having surfaced as of yet, but Subnautica has now been optimised for Xbox Series X and Xbox Series S - with the upgrade available for free!
This means you can also access it if you play the game via Xbox Game Pass, and based on what we've seen so far, the visuals have been noticeably improved, 60fps is now the default setting, and there are far less instances of pop-in.
Don't forget that Subnautica: Below Zero is also out now for Xbox One, Xbox Series X and Xbox Series S (it released earlier today), set two years after the original game. It features an all-new, sub-zero expedition in the arctic region of Planet 4546B, and you can pick it up right now from the Microsoft Store for £29.99 / $29.99.
