Overview
- Unknown Worlds said Thursday that Subnautica 2 sold more than 4 million copies in under a week after selling about 1 million in its first hour and roughly 2 million within the first half day.
- The Early Access launch pushed very high concurrent player counts on Steam and Xbox platforms and produced broadly positive Steam reviews praising co‑op play and deeper survival systems.
- Developers have issued rapid updates, with Hotfix 2 deployed to add more early Silver and late-game Troilite, reduce Hammerhead creature aggression, and fix crashes and teleportation bugs.
- Hotfix 2 also revised the game's Terms of Service and privacy policy, will prompt players to re-accept the terms, and adds an in‑game option to turn off telemetry.
- Strong early sales have real financial weight for Unknown Worlds because the performance feeds into an ongoing Delaware-era earnout dispute with parent Krafton and could affect the studio's potential payout.
