Subnautica 2 sells two million copies in less than 24 hours

Subnautica 2 sold 2 million copies in just 12 hours after its May 14 early access launch.

Concurrent players peaked above 651,000 across Steam, Epic Games Store, and Xbox.

Strong Steam review scores and four-player co-op appear to be fueling the game’s rapid success.

The launch points to unusually high demand for a niche survival sequel across major platforms.
