How to build a base in Subnautica 2

Before you can begin making your first base in Subnautica 2, you'll need to unlock and craft a Habitat Builder tool. Using this tool, you can access a build menu containing corridors, doors, production machines such as a Fabricator, and miscellaneous decorative items.

Subnautica 2 also offers a small tutorial in the form of a NOA entry within a nearby structure. By traveling 80 meters southeast of the Lifepod, you'll find a Welcome Center building that's run out of power. Inserting a basic battery into the Welcome Center's wall panel will power its Bio Lab and NOA, who'll give you a rundown of how base building works.

How to unlock the Habitat Builder tool

Unlocking and crafting the Habitat Builder tools requires making a Survival Multitool and Scanner. You can craft the multitool using three titanium, while the scanner uses the following resources:

Titanium (2)
Quartz (2)
Basic Battery (1)

Titanium is the easiest of the required resources to find, as it's an abundant material you'll find around your Lifepod. Glass requires two quartz, which you'll also quickly acquire early on. Basic batteries are slightly trickier, as you'll need to collect copper from nearby caves.

Your next step after making these tools is to search for two old Habitat Builder tools that you can scan. Here's a breakdown of two possible locations:

Head back to the Welcome Center. Next to the "Welcome Center" sign outside of its entrance is a metal box containing a Habitat Builder tool.
