Guide Last Updated:
6/23/2024

Subnautica: Below Zero is the sequel to the massively popular original game Subnautica. It has 13 achievements and in this guide we'll be going over how you can get all of them!

Drop in the Ocean

Drop in the Ocean - Locate your Drop Pod

The first achievement we get after we arrive on planet 4546b is "Drop in the Ocean" for locating your drop pod. You'll have a marker on your compass and screen indicating where the drop pod is, so you'll just have to navigate over there and once you go inside this achievement will pop.

Jukebox Hero

Jukebox Hero - Install a jukebox

Next up will be "Jukebox Hero" for installing a jukebox. That'll mean we need to do two things. First we need to scan a jukebox which you can find over in the abandoned Alterra base on Delta Island. This is the same island that has the big communications tower. After you've scanned that you can just go construct a jukebox with your habitat builder at your base and the achievement will pop.

Xenobiology

Xenobiology - Encounter a sapient alien lifeform.

Then "Xenobiology" will be for encountering a sapient alien lifeform. You'll need to go down in the Twisty Bridges biome to find some alien technology and follow it down to the Alien Sanctuary Site. You'll end up coming up to an Architect building where you'll have to download some stuff in the storage cube area and then this achievement should pop.

Truckin'

Truckin' - Construct a Seatruck

"Truckin'" will be for constructing a seatruck. In order to do that you'll need to first find some fragments for it. You can find those down in the twisty bridges biome and the deep twisty bridges. Once you have those fragments you'll need to first get a mobile vehicle bay to craft the truck, and you can find fragments for that around the arctic kelp caves, the arctic kelp forest, and the twisty bridges.

Once you have the mobile vehicle bay you can craft the seatruck with a Titanium ingot, an advanced wiring kit, 2 glass, 3 lead, and 1 power cell.

Another Survivor

Another Survivor - Find Marguerit's home.

Next we'll get "Another Survivor" for finding Marguerit's home. It's probably possible to do this without the sea truck, but having it will make a lot easier. You'll need to go past delta island out to the tree spires biome and go towards the "Pilot - Last Known Position" marker at the edge of the lily pad islands. Basically just go down fairly deep into the tentacle looking area's caves and you'll find Marguerit's base about 366 meters down under the water.

Spy Pengling

Spy Pengling - Construct a spy pengling.

Then there's "Spy Pengling" for constructing a spy pengling. Just like most things in the game, you'll need to find the fragments for it in order to learn how to craft it. You can grab the fragment for the pengling from over at the Glacial Basin, near Marguerite's base, and over in the Phi Robotics Center near the bridge you have to fix. Once you have the fragment you can make it with 2 titanium, a wiring kit, 1 silicone rubber, and 1 battery.

Pirate Radio

Pirate Radio - Disable Alterra communications.

"Pirate Radio" will be for disabling Alterra communications. This is another step in the story and you'll need to make a test override module in order to do it. That in itself isn't too bad because the singular fragment you need to scan is in Marguerit's base, but part of the recipe includes the parallel processing unit. That one can be hard to find fragments for unfortunately as you have to go to different pieces of the Mercury II wreckage. Because it seems to be a spot people get stuck at, I know was for a little while, I made a guide detailing the easiest and quickest way you can get those fragments and craft it.

EASIEST Parallel Processing Unit Fragments Locations Guide

Necessary Repairs

Necessary Repairs - Repair the bridge.

Next we'll need to get "Necessary Repairs" for repairing the bridge. This is part of the story that you'll get after talking to Marguerit and you'll get a marker for this bridge that needs to be repaired. In order to do the repair you'll need one hydraulic fluid which is going to require 1 creep vine cluster and 4 gel sacks.

Like Riding a Bike

Like Riding a Bike - Ride a Snofox.

Then we can move on to "Like Riding a Bike" for riding a snowfox. Like most other things you'll need to first find fragments for it, and those you can find in the glacial basin, Marguerit's base, and the Phi Robotics Center. Once you have those you can craft it at a snowfox hoverpad with 2 magnetite, 1 battery, 1 lubricant, and 1 titanium.

Dressed for the Weather

Dressed for the Weather - Construct a cold suit.

"Dressed for the weather" will be for constructing a cold suit. In order to do that you'll need to get those fragments which will also be in the Phi Robotics Center.

Each piece will take some amount of fiber mesh and snow stalker fur to make, and snow stalker fur can be tricky to get. You'll need to have a spy pengling and a remote made, then head up around the area near the phi robotics center, and you'll throw down a spy pengling kind of nearby a snow stalker, then use it to walk up to it and start taking fur. It has four inventory slots so just fill up on fur and then walk it back to you. Be sure to keep your character at a safe distance though so you don't get attacked by the snow stalker.

Finding the Cure

Finding the Cure - Use the antidote.

Next we have "Finding the Cure" for using the antidote to cure the big frozen leviathan of the Kharaa bacteria. In order to get the antidote you'll need to have a spy pengling and remote again. You'll need to go up to the glacial basin in this area to find a little cave to put the pengling in and grab the antidote from a container.

You'll then need to find where the frozen leviathan is to actually use it. It's up in the Phi Excavation Site in the Glacial Basin which makes it tough to find, but if you check out the video guide I show a route that you can go to find it much easier.

Once in there you just have to get up to the leviathan frozen in the ice wall and use the antidote on it.

Out of Mind

Out of Mind - Construct an alien vessel

Then there's "Out of Mind" for constructing an alien vessel. This one takes a bit because there's a few facilities we have to find for it to get the Architect's Organs, Skeleton, and Tissue.

The Skeleton can be found in the Deep Lilypads Cave Cache about 620 meters deep.

The Tissue can be found in the Arctic Spires Cache above sea level.

The Organs can be found in the Crystal Caves Cache about 820 meters deep.

I saved the organs for last because down there is part way to the fabricator base that you need to go to in order to actually put those together and construct the vessel which is further down the depths around 950 meters deep. You definitely want to watch out for the leviathans hanging out down here.

Into the Unknown

Into the Unknown - Leave 4546B.

For the last achievement there's "Into the Unknown" for leaving the planet 4546B. This will be available after you construct the alien vessel and he'll give you a new location to meet him at when you're ready to leave. Then just head there and go through the ending mission until you finally end the game and get the achievement.
