There’s something uniquely terrifying and beautiful about the Subnautica series. Few survival games capture the tension of exploring an alien ocean quite like it. The blend of wonder, fear, and discovery keeps players hooked. Now, with Subnautica 3 in development, fans are eager to know what’s coming next.
The third major entry promises new environments, fresh mechanics, and even multiplayer—a long-requested feature. Whether you’re a veteran diver or new to the series, this guide covers everything we know so far about Subnautica 3, plus tips to sharpen your survival skills before launch.
What Is Subnautica 3?
The next installment in the Subnautica franchise is often referred to as Subnautica 3, though some developers have labeled it as Subnautica 2 (since Below Zero is technically a standalone expansion rather than a numbered sequel). Regardless of the title, this game marks the third major entry in the series.
Confirmed Features
- Developer: Unknown Worlds Entertainment, under Krafton.
- Release Window: Early Access has been delayed to 2026.

Why Fans Are Excited
The Subnautica series thrives on three key elements:
- Immersive Exploration – Stunning underwater biomes, bioluminescent creatures, and vast alien landscapes.

Adding multiplayer to this formula is game-changing. Fans have dreamed of exploring alien seas with friends, building bases together, and defending against massive predators as a team.
