The Expansion Pack is an upcoming paid DLC for Subnautica. The full release date is currently planned for early 2019.

Currently all that is known is that the Arctic Biome will be a large part of the game, possibly the entire map. It is also known that a weather system will be featured.

The Arctic expansion will be a separate game mode with a different different protagonist rather than Ryley Robinson, and takes place in a separate map.
