About this game

*Please make sure your device is supported before purchasing Below Zero!*

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 have played the first part on the ps5 I wasn't expecting that the below zero experience on the mobile would be as enjoyable as the console, devs have done a great job porting it on the go, it gets my motorola edge 70 pro little bit warm but it's expected as game has very good visuals, i would highly recommend to the people who wants the full on experience on the go

I prefer this to the first game. it's less claustrophobic the biomes are very rich and pretty and less terrifying and the storylines continue to be interesting and building on lore. there were def some parts where I needed to look up what to do next. I think it's easy to miss clues and some details when playing on mobile
