What developers have said about 1.0
Unknown Worlds Entertainment has stated in multiple developer diaries that Subnautica 2 will remain in Early Access for at least 18 months. Based on the February 2026 launch, the earliest possible Subnautica 2 full release date is August 2027. However, the developers also noted that the timeline could extend depending on community feedback and feature scope.
