Subnautica 2 has sold over 5 million copies, following its initial sales of 2 million within 12 hours and 4 million shortly after release. The game recently launched its first major update, version 1.1, which allows players to engage in lighthearted interactions with sea creatures, though they still cannot kill them. The update also improved base building mechanics, including better placement for the fabricator and the introduction of a dedicated storage structure.
