Below Zero is the next chapter of Subnautica, the underwater survival open world set on an alien ocean planet.

Submerge yourself in an all-new, sub-zero expedition in an arctic region of Planet 4546B. After crash landing planetside, set out into frigid waters to investigate what happened to your sister...

Discover new biomes, creatures, challenges and story! Below Zero expands the Subnautica universe, diving deeper into the adventure and mysteries introduced in the original game.

UNCOVER THE TRUTH - Who were the aliens who came here before? Why were they on this planet? What really happened to your sister? And will exposing the truth give some closure to your loss?

SURVIVE THE COLD - The freezing temperatures of this arctic region pose a new challenge. Craft a toasty cold suit, sip on piping hot coffee, and warm up next to Thermal Lilies to stave off the chill.

CRAFT YOUR WAY - Survive the harsh climate by constructing extensive habitats, scavenging for resources, and crafting equipment. Blast across the snowy tundra on a Snowfox hoverbike. Cruise through enchanting and perilous biomes in your modular Seatruck.

EXPLORE THE PLANET - Swim beneath the blue-lit, arching expanses of Twisty Bridges, be mesmerized by the Crystal Caverns, venture into the icy caves of Glacial Basin or maneuver between erupting Thermal Vents to discover ancient alien artifacts.

MEET NEW CREATURES - Something undiscovered lurks around every corner. Swim through the giant Titan Holefish, encounter the haunting Shadow Leviathan, and visit the adorable Pengwings. Keep your wits about you. Not all creatures in this strange world are friendly.

first of all, I'm very excited. subnautica below zero and subnautica are on mobile. This is perfect for if you want to play the game without having a console or PC. or if you want to play on the go. I will always say this. it's very surreal. whether you are on mobile or on PC/Console. you will love this game. 👍🏻 Unlike before in the original subnautica mobile, The buttons are mini joysticks. everything's so much easier to move around!

Spoilers! love it. A beautifully done port to mobile, and a wonderful offline survival game that I personally prefer to the original game. Naturally at launch, some glitches are speckled around, but every prompt in the story triggered, each cutscene played perfectly, and controllers work nicely. I've been waiting for this, and am very glad to say it does not disappoint. My favorite game on the go, thank you very, very much, Unknown Worlds and Playdigious. Cheers! OH, and I CAN'T forget the scan-

been a fan of subnautica since it was in beta. worth every penny. one of the best if not the best in it's genre. think it would be nice if they added a auto grab option for mobile ports. can be difficult to negotiate all the options by touch, but honestly i don't mind a bit of added difficulty. adds to the experience. great game. great price.

I played Subnautica a few years ago on PC, but never really got too far. And since Subnautica 2 came out recently, I thought, why not play the previous games. I decided to try Below Zero first this time, and while I did like it, it's not really a perfect mobile port. It can be frustrating, and there are quite a lot of things I would like to comment on, but there's a character limit here, so... yeah. Overall, I still really liked and enjoyed the game, and will definitely try the first game next.
