Building a Seatruck - Subnautica: Below Zero Guide - IGN (2024)

"The Seatruck: Competing products are trucking hell."

Welcome to IGN's Subnautica: Below Zero walkthrough. This portion of the walkthrough will take you through building a SeaTruck, which will make further and deeper exploration much easier and safer.

After reaching the Delta Station and Phi Robotics Landing Pad, the next portions of the game will go much deeper under water. While you could safely swim to the Alien Distress Signal, or Sanctuary Zero, with fins and a Seaglide, we will be using a Seatruck in the next parts of the Walkthrough and find it makes exploration easier and safer—particularly important if you're playing on Survival or Hardcore mode!

The Seatruck first requires a Mobile Vehicle Bay. The Bay recipe requires one Titanium Ingot, Lubricant and a Computer Chip.

Building a Mobile Vehicle Bay

Computer Chips require gold, which is most easily found in Calverite Outcrops in the same aquatic cave system know as the Arctic Kelp Caves you previously hunted for silver. You will need to go deep into these caves; it's easiest to use your Scanner to search for outcrops. Collect several Gold chunks.

Once you have deployed your Mobile Vehicle Bay (which will float on the surface above wherever you deploy it), you are ready to build your Seatruck.

The basic Seatruck requires one Titanium Ingot, one Advanced Wiring Kit, two Glass, three Lead and one Power Cell. Many of these resources, like lead and Titanium, you will probably have found on your explorations by now. The Power cell is created from two Batteries and one Silicone Rubber, which you should have on hand from creating your Scanner, Seaglide and from Creepvine Seeds.

You can pin any recipe to the top of your PDA to more easily see what you are still missing.

The Gold in the Seatruck recipe will probably take the longest to find, so be sure to collect several chunks in the caves to prevent return trips. You will also need to scan three Seatruck Fragments in order to synthesize the blueprint. These fragments can be found in the Thermal Spires, Twisty Bridges, Deep Twisty Bridges and Purple Vents. They span randomly.

After Building Your Seatruck

The Seatruck is a modular deployable vehicle that can be upgraded and added to later on with additional recipes.

You will probably want the Seatruck Depth Upgrade MK1 most quickly, because the base Seatruck depth is 150M. Two more Seatruck Depth Upgrades, MK2 and MK3, are available after the first. These upgrades are immediately available after building your Seatruck, but they require Plasteel Ingot and Enameled Glass for the first, and more complicated ingredients for the next two.

The Seatruck has a health meter and can take damage by attacks from fuana or running into obstacles. It will be destroyed by going past its depth limit or crush depth. The MK1 depth upgrade allows you to go 300 meters deep, and the MK3 depth upgrade increases crush depth to 1,000 meters deep.

Seatruck and Seatruck Modules

Looking for the complete list of Seatruck and Seatruck Module recipes in Subnautica: Below Zero? We've got you covered! Check the table below for details on each.

Note that most modules require either the Mobile Vehicle Bay or Modification Station to build. However, they're not necessary at this point in your playthough. We're just listing them for your knowledge. You can also check the How to Craft Tools and Deployables page to learn more about the various upgrades and recipes.
