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.

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.

I thoroughly enjoyed the original Subnautica and found the experience equally engaging in 'Below Zero.' The introduction of new creatures, diverse fauna, and a compelling narrative provided everything I seek in a survival game. I anticipate the developers will consider making 'Subnautica 2' accessible on mobile platforms. This continues to be an exceptional game series.💙

A very good experience. It's not a small game. The map is smaller. It's a sequel, not a dlc. Moving around in vehicles is much more fun and natural than in the first game. The game runs well on a mid-range mobile device. For this price, highly recommended. For the typical mobile gamer who's more superficial, it would be good to provide more guidance on the locations of the ship (and its three components needed to advance the story) and the final location, as the clue is very basic.
