Subnautica 2 is coming soon
In related news, Subnautica 2 will finally enter Early Access in 2026. Unknown Worlds originally stated that the delay from 2025 would allow the team to respond to playtest feedback and expand release builds, but the delay later became part of a wider legal dispute between publisher Krafton and former studio executives. In the latest twist in this legal drama, a Delaware Court of Chancery judge ordered Krafton to reinstate former CEO Ted Gill and restore his full control of the game's early access launch in March 2026. Krafton previously claimed Gill had neglected his responsibilities on the project, along with game director Charlie Cleveland and studio co-founder Max McGuire, and cited this as a reason for their dismissal. The ousted executives disputed those claims and filed a lawsuit, claiming the publisher removed them to avoid paying $250 million in bonuses tied to performance targets agreed upon as part of Krafton's 2021 acquisition of Unknown Worlds.
