Developer Unknown Worlds has revealed first details of Below Zero, its long-teased arctic expansion for superb underwater survival adventure Subnautica.
Below Zero is described as a "new chapter" in the Subnautica universe, and unfolds across a previously unseen ice-bound region of planet 4546B - the ocean world that players explored during the base game.
Unknown Worlds says that it's still developing the concept of Below Zero, but that the expansion will retain the core mechanics of the original Subnautica, including base building and open-ended exploration. These will be joined by new elements, with the developer currently considering the likes of thermal management, and more voiced dialogue for the central story.
