Subnautica 2 Adds a New Planet and Co-Op in 2025 IGN

Wet and wild ocean exploration sequel Subnautica 2 was announced at the Xbox Partner preview will arrive on PC and Xbox Series X and S in 2025 via the Xbox Game Preview program. It'll also be available on Game Pass on day one.

The new installment in the Subnautica series will take players to a new planet, complete with new environments, flora, and fauna to discover. It also has co-op for up to four players, a new addition to the series.

"Whether you’re bringing the experience of your previous adventures with you, or are new to the Subnautica games, you’ll get to explore lush new environments, encounter fascinating creatures around every corner, and uncover the secrets at the core of this mysterious planet," teased Unknown World's Community Manager Donya Abrams in an Xbox Wire post.

"But as familiar as things might seem to seasoned players at first glance, Subnautica 2 will offer new and unique experiences that will keep you on your… fins."

Last month, developer Unknown Worlds responded to fan concerns over the latest installment, promising "no season passes. No battle passes. No subscription," that cooperative play was entirely optional and not a threat to the single-player experience.

The last game in the series, Subnautica: Below Zero, was released in 2021 and got an impressive nine out of ten in its IGN review.
