Listed below Zero is explained as a “new chapter” in the Subnautica universe, set two years after the occasions of the original video game. The Steam page avoids using the word “sequel”, and I expect it’s closest in type to that feared portmanteau, the “expandalone”. Expect a brand-new icy region, brand-new animals including lovable penguinlikes, and a similar core loop of expedition and base growth to the original game.
John enjoyed his time with it back in January 2019, while being surprised at both its aspiration and at how early in advancement it was. The initial Subnautica sits at the top of our list of the finest survival video games.
