Subnautica 2 release date
Confirmed launch timeline
The Steam Appdetails response lists Subnautica 2 as released on May 14, 2026. The same response marks the product as Early Access, not as a finished 1.0 release. Treat this as the current access point, not a promise that final launch has happened.
What Early Access means here
The official Steam description says the world, creatures, craftables, narrative, tools, equipment, and vehicles can expand during Early Access. It also warns that players may encounter bugs, unfinished features, and performance issues. A purchase today buys the current build and the development process, not a guaranteed completion date.
Full 1.0 status
No captured official source confirms when Subnautica 2 will leave Early Access. The safe statement is: the 1.0 date is unconfirmed as of August 28, 2026. Any page claiming a specific final date should show a newer official statement from Unknown Worlds or an official store.

How to check for changes
Compare the Steam release field, the official site, and the Xbox listing. A retail page can change regionally, so record the store, region, timestamp, and screenshot or API response. Only promote a date to confirmed when the publisher or an official store states it directly.
