Subnautica 2 Enters Early Access with 5 Million Pre-Orders and 4-Player Co-op

Unknown Worlds launched Subnautica 2 in Early Access on May 14 across Steam, Xbox, and Epic Games, following 5 million wishlist signups. The sequel's defining feature is native 4-player cooperative gameplay—the original was single-player only—though solo play remains available. The studio will roll out iterative updates throughout Early Access before the full release.
