Krafton's new title "Subnautica 2" surpassed cumulative sales of 2 million copies just 12 hours after launch.
Krafton said on the 15th that Subnautica 2 recorded cumulative sales of 2 million copies and a peak concurrent user count of 651,000.
Krafton released Subnautica 2 in early access that day. The game launched simultaneously on Steam, the Epic Games, Inc. Store, and Xbox Series.
On Steam alone, peak concurrent users totaled 467,000. That is about nine times the all-time peak of 51,000 for the 2018 full-release predecessor, "Subnautica."
Early reactions from players are also positive. Steam user reviews are currently rated "Overwhelmingly Positive," and wishlist registrations have surpassed 5 million.
It is also drawing attention in viewership metrics. With 413,000 peak concurrent viewers on Twitch, it ranked No. 1 across all categories. On YouTube Live, it also topped the game category by surpassing 109,000 peak concurrent viewers.
Subnautica 2, developed by Krafton's subsidiary Unknown Worlds, strengthens exploration and survival elements against the backdrop of a new alien planet, unlike its predecessor. For the first time in the series, it introduces a four-player co-op mode.
