Subnautica 2, the new underwater survival game from Unknown Worlds, surged to the top of Steam's charts within an hour of its release. According to a press release, the game has already sold over 1 million copies.

As of this writing, Steam's charts show that Subnautica 2 is currently the fourth-most played game on the platform, with more than 460,000 concurrent players.

The only titles with more concurrent players right now are perennial heavy hitters Counter-Strike 2, Dota 2, and PUBG: Battlegrounds.

It's also worth noting that Steam's Subnautica 2 player count does not include players on the Epic Games Store or on Xbox, where the game is also now available.
