Console release date information

The console Subnautica 2 release date arrived in August 2026 for Xbox Series X|S and PlayStation 5. The console Subnautica 2 release date was three months after the PC launch because the team wanted to ship the first major content update simultaneously with the console debut. On the console Subnautica 2 release date, players received the same build as PC update 1, which included the Floating Islands biome and the Sea Truck MK3 depth module. The Xbox Subnautica 2 release date is important for Game Pass subscribers — the game is available on Game Pass Ultimate and Console tiers from day one of the console Subnautica 2 release date. A Nintendo Switch 2 Subnautica 2 release date has not been announced, though Unknown Worlds has stated they are evaluating the platform. The console Subnautica 2 release date pricing matches the PC Early Access price of $29.99.

Full 1.0 release date estimate

The full Subnautica 2 release date for version 1.0 is estimated for late 2028. Unknown Worlds has been cautious about promising a specific Subnautica 2 release date for 1.0, preferring to let the roadmap milestones dictate when the game is feature-complete. Based on the five announced content updates — August 2026, November 2026, February 2027, May 2027, and August 2027 — followed by a polish and bug-fixing phase, the realistic Subnautica 2 release date for 1.0 sits somewhere in Q3–Q4 2028. The Subnautica 2 release date for the full game will likely be announced six months in advance, giving players time to prepare for the price increase. When the full Subnautica 2 release date arrives, the game will include all planned biomes (~15 total), all vehicles (~7 total), and the complete five-act story.
