Share: Subnautica: Below Zero is a game about crafting for convenience. This frigid follow-up to Unknown Worlds’ seafaring survival sandbox subscribes to the same blueprint as its 2017 predecessor, plunging you into an aquatic open world and willing you to explore it. Where you go, and how you get there, is entirely up to you. While there is a loose story to follow involving shady corporations and missing siblings, the main thrust of this arctic outing is mining materials that will ensure your survival is more straightforward. You’ll start the campaign with little more than a wetsuit and willpower, but as you slowly streamline your scavenging practices, you’ll end up with a sprawling underwater metropolis.
