After a tough road filled with controversy and lawsuits, Subnautica 2 is finally locked and sealed for its release on May 14th. The game will launch on PC via Steam and Epic, and is also making its way to Xbox Series X|S and straight into Xbox Game Pass. With 2 days left, Unknown Worlds have now opened pre-ordering on all platforms, and surprisingly, preloading on Steam too.
Subnautica 2 Preordering Starts
While everyone thought preordering, much less preloading, was not going to be available for Subnautica 2, the team had other plans. Although this wasn’t their initial intention, even outright saying it on the official Discord server, the team ultimately changed their minds and allowed it.
Probably thanks to an earlier announcement of the game hitting 5M wishlists on Steam, plus the massive hype of the game in general, Unknown Worlds felt the excitement was so palpable they just had to do it.
Preordering Subnautica 2 is now available on Steam, Epic Games Store, and Xbox Store. Priced at $29.99 / £25.99 / 29,99€, with regional pricing in effect, it’s not a bad deal. Yes it’s early access but according to playtest users, average playtime at its current state is 20 hours, with some even clocking in 70 hours. That’s a big jump from the intended 12 hours.
As for discounts, a 50% off Subnautica Deep Ocean Bundle is available on Steam which includes Subnautica, Subnautica Below Zero, and Subnautica 2. If the first 2 releases are already owned, a 10% discount is offered for Subanutica 2.
Subnautica 2 Preload and File Size Details
With preordering underway, preloading has also gone live on Steam. Preload download size is 12.9GB but the full space required for launch is 14.56GB. Preloading on Xbox Series X|S and on Xbox Game Pass is also live as of writing.
Subnautica 2 will officially launch on Early Access on May 14, 2026 at 8AM PT / 11AM ET / 4PM GMT.
