What Subnautica 2 is
Subnautica 2 is an adventure game developed by Unknown Worlds Entertainment and released in 2026. It is available on Xbox Series X|S and PC (Microsoft Windows). It runs on Unreal Engine 5.
The premise, in the publisher's words
The Alterra colony ship Cicada, bound for the desert world of Zezura, inexplicably diverts course and crash-lands on an uncharted ocean moon called Proteus. The world's extreme atmospheric pressure and heavy metal contamination means all human life will perish within months. To survive, the ship's AI uses "reprinting" technology to restore backed-up consciousness into new bodies, but the process causes severe memory loss. Decades after the original colonists vanish under mysterious circumstances, a new investigator is printed to uncover what happened to them and confront the secrets hidden beneath the alien ocean.
How it plays
It is played from a first person perspective. Its themes are action, science fiction and survival. It supports multiplayer for up to 4 players online. Local play supports 1 players. Available modes: Co-operative, Multiplayer and Single player.
How long it takes, and what that costs
The main story runs about 21 hrs.
What you need to run it
The minimum specification calls for Intel Core i5-8400 / AMD Ryzen 5 2600, 12 GB RAM and GeForce GTX 1660 6GB / RX 5500 XT 6GB. A 12GB memory requirement is demanding — worth checking before you buy, because 8GB is still common in older and budget machines. Install size is roughly 50GB. Both tiers are compared side by side on the requirements page, and you can check your own parts against them without installing anything.
What it costs, and where
Storefront pricing varies enormously by country: India is the cheapest region we track at ₹1,800.00 (about $18.88), while United Kingdom pays £25.99 — 1.8 times more. In Pakistan it is priced at Rs 21 on Steam, which is about $20.99.
What it launched against
Subnautica 2 launched on 14 May 2026, within three weeks of 007 First Light, Forza Horizon 6, LEGO Batman: Legacy of the Dark Knight and Directive 8020. It arrived 6 years into the Xbox Series's life, so it was built for hardware developers already knew well.
Released around the same time: 007 First Light, Forza Horizon 6, LEGO Batman: Legacy of the Dark Knight, Directive 8020.
