Subnautica 2

Deeper, and This Time You Can Bring Someone

The original Subnautica built a devoted following by doing something most survival games refuse to do: make the ocean feel genuinely alien and genuinely terrifying. Unknown Worlds Entertainment returns with a sequel that keeps that core tension intact while adding the one thing fans had long requested, cooperative play for up to four players.

The Experience

Driven from their home by conflict, players arrive as Pioneers aboard the colony ship CICADA, only for the mission to go wrong before it begins. Stranded on an unfamiliar alien world covered in water, survival depends on crafting tools, building and customizing underwater bases, and piloting a submersible called the Tadpole through biomes that range from the luminous to the deeply unsettling.

This is the next chapter in the Subnautica series, set on an entirely new planet rather than continuing the original's story directly. The ship's AI insists the mission must continue, and uncovering why provides the narrative thread that pulls players deeper into the unknown.

Who Should Play This

Subnautica 2 launched into Early Access on PC via Steam in May 2026. The developers estimate two to three years of Early Access development ahead, meaning bugs, missing features, and an incomplete narrative are part of the current package.

Players new to the series can start here without prior knowledge, though those who dislike unfinished games should wait for the full release.
