Along with searching for resources, building bases, and avoiding predators, many players are already trying to unlock all of the game’s achievements. There are only thirteen to get, though they require players to complete every key quest in the game. So, for anyone stuck, here’s how to unlock all thirteenSubnautica Below Zero achievements.
Updated on Jun 08, 2025, by Jack Pursey:Subnautica: Below Zero received its full release over five months ago, and many players have now completed their adventure in Planet 4546B. Moreover, the game recently joined its predecessor on Microsoft’s Game Pass subscription service, giving numerous players the chance to explore the game’sbeautiful yet horrifying horrifying ocean depths.
Now that many players have completed the main story, a fair few diehard players will be looking to earn all the achievements. To help such players out, we have updated this list to include a short and sweetSubnautica Below Zero achievement guideunder each entry.
Drop in the Ocean
Drop In The Ocean is by far the easiest achievement in the game.When starting a new campaign, players will be on the wrong end of a crash landing, much like in the firstSubnautica. Following the crash, the player will see their Drop Pod falling into the ocean in the distance.
To unlock this achievement:
Like Riding a Bike
One ofSubnautica: Below Zero’s new features isthe introduction of arctic biomes. The biomes add a nice change of pace to the game, letting players take a break from the dangers that lie below the water. Unfortunately, the artic biomes don’t provide a safe haven, as they have their own set of troubles for players to contend with. Thankfully, the new biomes are partnered with a new vehicle, the Snowfox.
Truckin'
The Snowfox isn’t the only new vehicle introduced inSubnautica: Below Zero, as the game also offers the player a Seatruck. Initially, the vehicle is very similar to the Seamoth from the previous game, though players will be able to expand it by constructing and attaching modules.
Spy Pengling
Yet another new item inBelow Zerois the Spy Pengling. The small robot is predominantly used to enter inaccessible caves, though it also has other benefits such as being able to take fur from a Snow Stalker.
Necessary Repairs
One thing that differentiatesSubnautica: Below Zerofrom most otheropen-world gamesis the lack of set-quests. There are only a handful of definitive quests for players to complete inBelow Zero,one of which is repairing the bridge in Glacial Bay.
Xenobiology
For most players, Xenobiology will be the second achievement that they unlock, following Drop in the Ocean. It is a key story moment in the game that sets up one ofSubnautica: Below Zero’s main quest lines.
Another Survivor
Unlike its predecessor,Subnautica: Below Zerowill give the player another character to interact with sporadically throughout the campaign. Marguerit Maida became a resident of planet 4546B after a Reaper Leviathan destroyed the Deep Grand Reef Degasi Base where she worked. She managed to kill the Reaper and has its skull hanging in her base.
Pirate Radio
Once players reach the aforementioned base of Marguerit Maida, they will be able to scan the Test Override Module. The Test Override Module is needed to disable Alterra’s communication tower, which can be found at the top of Delta Island.
Out of Mind
Once players reach the previously mentioned Sanctuary Zero and have the unpleasant sensation of Al-An blasting into their head, the game’s main quest will become clear. Players need to construct a vessel for Al-An so that he can leave Robin’s head.
The achievement Out of Mind is unlocked once players successfullyconstruct the vessel. To construct the vessel, players need to find the Architect Organs in the Crystal Caves Cache, find the Architect Skeleton in the Deep Lilypads Cave Cache and find the Architect Tissue from the Arctic Spires Cache. Once all three have been found, players can travel to the Fabricator Base and construct the vessel.
Jukebox Hero
From the game’s most challenging achievement to one of its most enjoyable.Subnautica: Below Zerolets players take a break from being chased by Squidsharks and Shadow Leviathans by unwinding in their base and listening to some of planet 4546B’s best tunes.
To unlock Jukebox Hero, players need toconstruct a Jukebox for their base, which can be done with the Habitat Builder.
Dressed For The Weather
The Arctic Biomemay provide a nice change of pace for players, but as mentioned before, it comes with its own set of issues. Along with Snow Stalkers and an enormous Ice Worm, the player will also have to be careful of their body temperature when venturing into the arctic. Thankfully, there is a solution to the threat of hypothermia, as players can construct a Cold Suit.
Finding the Cure
One of the most striking and memorable moments inSubnautica: Below Zero, especially for those who didn’t watch the trailers, is when the player is greeted by an enormous Leviathan in an ice cave. Thankfully, the Leviathan is frozen, so players don’t need to worry about a sudden ambush. Upon further inspection, it will become clear that the Leviathan is infected with Kharaa.
To unlock Finding the Cure, players need to use theKharaa Antidoteon the Frozen Leviathan. The antidote was hidden by Robin’s sister, Sam, in a Glacial Basin cave that is accessible with the Spy Pengling.
Into The Unknown
Into The Unknown is the final achievement unlocked in the game. Once players construct Al-An’s vessel, they will be able to leave Planet 4546B with him for the Architect planet.
The achievement will be unlocked onceplayers reach the Architect planet, which appears to be hinting at the release of a thirdSubnauticagame.
Subnautica: Below Zerowas fully released on July 14, 2025, and is available on PC, PlayStation 4, Xbox One, PlayStation 5, Xbox Series X/S, and Nintendo Switch.
