KRAFTON and developer Unknown Worlds have released the first major update for the early access version of Subnautica 2. The “EA1.1” patch introduces expanded “biomod” systems, quality-of-life improvements for four-player cooperative play, and new environmental puzzles. This update follows a strong market debut, with the title surpassing millions of cumulative sales within weeks of its May 2026 launch.
Expanded Gameplay Mechanics and Research Systems
The EA1.1 update significantly deepens the game’s core progression systems. According to KRAFTON Japan, the “biomod” system—which allows players to temporarily adopt the biological traits of local fauna—has been expanded to include six modules, up from the original four. Players can now unlock additional passive biomod slots by utilizing the bioscan tool on new creatures, providing more agency in how they develop their character’s survival capabilities.
Exploration has also seen a structural overhaul. Unknown Worlds added two new research facilities, dubbed “biolabs,” to the game world. Beyond the labs, the developers have introduced new routes and oxygen-management puzzles within shipwrecks, forcing players to rethink their approach to navigating hazardous, submerged environments.
The original Subnautica series established the marine survival genre and has sold over 18.5 million units worldwide. Subnautica 2 is the first in the franchise to support native multiplayer for up to four users.
Cooperative Play and Quality-of-Life Adjustments
One of the primary focuses of the EA1.1 update is streamlining the multiplayer experience. Previously, audio logs would play automatically for all team members upon item discovery, which often interrupted group coordination. Under the new system, audio logs are saved to the player’s PDA data bank, allowing each user to listen to lore entries at their own pace without disrupting their teammates.
Movement and base-building have also received technical polish. Players can now sprint outside of water—including on land and inside bases—improving travel speed between objectives. For base-builders, the update adds dedicated storage structures and improves the placement utility for “Tadpole” docks and fabricators. These changes are part of Unknown Worlds’ ongoing “open development” strategy, where player feedback directly influences the game’s feature roadmap.
Future Trends in Survival Sandbox Development
When playing with a group, divide your tasks based on the new biomod upgrades. Assign one player to specialize in movement-based modules to act as a scout, while others focus on structural or survival-based biomods to maintain the base.
