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

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.

FEATURES

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.

Thank you so much for bringing this masterpiece and its big brother to mobile! These are the first two premium games I've ever purchased. I've wanted to experience them for a long time, but like many people living in Asia, I don't have the means to buy a powerful gaming PC. I'm having an amazing time playing them. Please, in the future, when smartphones are capable of properly supporting Unreal Engine 5, consider bringing Subnautica 2 to mobile as well! Long live to your studio 🐙🫶

Not as good as the OG Subnautica, though the Seatruck is awesome

My report on block blast

My report on Subnautica below zero

There was a few issues that made it not a five star game for me because I tried getting gel sack seeds but when I tried getting the gel sacks when they got put into open water they phased through the ground also when I saved me game it took me back to when I was getting the snow fox which was 30 minutes before I saved these were pretty annoying since I had to scan all the items and get the gel sacks

Very good port

The game itself is very fun to play and I’ve caught myself staying on long after I thought I would stop after “one last task.” If this had been released without the original Subnautica, there would have been few complaints. Compared to Subnautica, the two stories in Below Zero can be a distraction. I’ve caught myself wondering which story I should resolve first. While the original has one main goal that you can focus on at your own pace. Map size is another issue. Below Zero has a smaller map. So exploring ends too quickly for me. But the designers did come up with fun biomes to explore. I downloaded this game aware of the faults, and I still enjoyed it. It’s not as engaging as the original, but it is still a fun game to play if you finished the original game, and still want to see more of the game world.

W GAME

you can kidnap penguins and have pet whales, and there also ELDRITCH BEINGS THAT ARE 60 METERS LONG LIKE THE LAST GAME, suggest trying 1, 2 and below zero, also unknown worlds, when will subnautica 2 come to mobile, cause I like these games. Also there's a spot that mockups me out of the map somewhere near delta station dock in a ice worm trench

Good but I’ve experienced one glitch

Hi so I went to a part of land where there was some buildings and I went to explore them and this is where the glitch happened. Once I got to the bottom of the hill area I stepped on the snow and i instantly fell through the map. I was stuck under the snow and couldn’t get out. I was so annoyed.😒. Could you please fix this glitch for us. Thank’s.
