Subnautica 2: updates and performance in early access

Subnautica 2, the sequel to the successful underwater survival game, launched in early access on May 14, 2026. Developed by Unknown Worlds Entertainment, the game quickly gained significant popularity, averaging around half a million copies sold per day. Since launch, several updates have been released focused on performance and gameplay improvements.

Gameplay and features

Subnautica 2’s gameplay builds on the successful design of its predecessor, introducing new elements such as improved fauna AI and additional resource zones. One of the most talked-about changes is the decision to include unkillable fish in the game, which some players say affects the gameplay experience. The change has sparked mixed reactions within the community.

Updates and improvements

The May 22, 2026 update was an important step for the developers. The patch added more silver resource zones to the early-game region and expanded the late-game region by introducing additional troilite resources. Alongside performance improvements at the highest graphics settings, adjustments were also made to Hammerhead AI. They no longer follow players back to their base, which improves the game’s flow.

In addition, bug fixes were implemented for issues that sometimes teleported players back to their base while exploring in the modular vehicle, the Tadpole. Another issue was also fixed where players would stop receiving oxygen after dying from hunger or thirst while driving the vehicle.

Community and feedback

The community response has been mixed. While some players appreciate the additions and improvements, others are concerned about the unkillable fish and their impact on the game. The developers have said they are working on further changes to address player feedback, including adjustments to creature balance and the game’s overall performance.

Future updates

Unknown Worlds Entertainment has announced that additional updates will be rolled out soon to fix further issues. Hotfix 3 is expected in the first half of June 2026. This patch will focus on player feedback and bring further optimizations to the Subnautica 2 experience.

With ongoing updates and community involvement, it is clear that Subnautica 2 continues to evolve, and the developers remain committed to delivering an improved underwater experience.
