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!

I really loved subnautica, finished it 3 times. it's disappointing and downright bewildering to see just how they managed to ruin the formula for this spinoff. it's hard to even put into words, the magic is just gone and no matter how much work clearly went into it, it feels completely soulless. the writing and voice acting is downright atrocious, the worst I've seen in a game in YEARS. That certainly doesn't help. I highly recommend the original game though, that one is a 10/10.

Still a good game & a decent port. This runs better than the previous game but does suffer the same bugs. Sometimes the character randomly swims up & won't stop, backing up the seatruck in some environments causes it to be stuck, & if you swim up the sea till you see the skies & then dive down, the entire map wont load, turning it to a void, but going up again sometimes fixes the issue. Things need to be ironed out but it's still a great game regardless. A very beautiful ocean of death.
