During a massive cold front, the last thing you might want to think about is diving beneath an arctic surface, but Subnautica was never about making you comfortable. That feels like the thesis statement behind the newest Subnautica game, which puts you both above and below the ice.

Check out the first teaser trailer for Subnautica: Below Zero, which is out on Steam Early Access today.

There’s a host of new freakish creatures that will no doubt make your existence frightening, new arctic biomes, alien artifacts to investigate, and new mysteries to figure out.

The game launched on Early Access today as totally standalone content, essentially a sequel, which means you don’t require Subnautica at all the play. That’s good news if you grabbed the game last month on the Epic Games Store for free, since it in no way affects the Steam version of Below Zero.
