Subnautica 2 Launches in Early Access: 5 Million Wishlists and 4-Player Co-op
The long-awaited underwater survival sequel Subnautica 2 by Unknown Worlds has entered Early Access today, May 14, 2026, at 15:00 UTC — making it available on Steam, Epic Games Store, and Xbox Series X|S.
A New Planet, the Same Spirit
Subnautica 2 takes players to an all-new alien ocean world, preserving the soul of the original: survival, exploration, base-building, and a mysterious deep ecosystem. This time, Unknown Worlds centered 4-player cooperative play as a core feature rather than an afterthought.
What Is Available at Launch
The Early Access launch includes a substantial portion of the underwater biome, a full crafting and base-building system, several narrative events, and complete co-op mode. Developers describe the current state as stable and highly playable, with the full story and final content to follow later.
Platforms and Availability
Subnautica 2 is available on PC via Steam, Epic Games Store, and the Windows Store, as well as on Xbox Series X|S. Unknown Worlds estimates Early Access will last two to three years, placing a full release around 2027–2028.
Community Response
The original Subnautica community responded enthusiastically, with 5 million wishlists on Steam demonstrating extraordinary interest. The co-op mode garnered special excitement from players who always wanted to dive the deep with friends.
