Krafton's Unknown Worlds has rolled out the first update for the open-world survival crafting title 'Subnautica 2' since its early access debut. Unknown Worlds is sticking to an 'open development' model, crafting the game hand-in-hand with its community. This latest patch is a direct response to player feedback, focusing on refining the early-game experience and overhauling core systems.

The update expands the Biomod system, which buffs your character's capabilities. With two new Bio-Research stations added to the Coral Garden and Axum Ruins areas, the total unlockable Biomods has increased from four to six. You can now use the Bioscanner to unlock extra slots for passive Biomods. Furthermore, the PDA Data Bank—your in-game encyclopedia—no longer forces audio logs to play automatically; you can now trigger them at your own leisure, which is a massive relief for those playing in co-op.

Exploration and survival mechanics have seen a suite of quality-of-life improvements. The shipwreck area now features new traversal routes and oxygen-based puzzles to spice up your deep-sea scavenging. On top of that, you can finally sprint while on land or inside your base. The Tadpole dock and fabricator placement have been made significantly more intuitive, and new storage-specific structures should make base management far less of a headache. The team has also polished rendering, creature behavior patterns, and the overall UI.

Subnautica 2 surpassed the 5 million sales milestone by early June. Fernando Melo, the General Producer at Unknown Worlds, noted that the team focused on polishing the core gameplay loop for this update, promising to continue expanding the world alongside the community. Lee Jin-hyung, Head of Krafton, credited the rapid 5 million player milestone to the creative vision of Unknown Worlds and the unwavering support of the global fanbase, pledging continued support for future updates and stable service.
