Subnautica 2 Habitat Builder: Unlock and First Base Build

The Habitat Builder is unlocked by scanning 3 fragments found near small wrecks in the Safe Shallows and Kelp Forest. Once unlocked, craft it with 1 computer chip, 1 wiring kit, and 1 battery. Then you can build base compartments, power sources, and interior modules.

Guide Steps

Step 1: Find Habitat Builder fragments

Search around small wrecks and debris fields in the Safe Shallows and along the Kelp Forest border. Fragments are small, rectangular device pieces on the seafloor. You need to scan 3 fragments to unlock the blueprint. Use the Scanner on each one.

Step 2: Gather crafting materials

You'll need: 2 copper (limestone outcrops), 1 silver (sandstone outcrops, deeper areas), 1 gold (sandstone outcrops), 2 table coral samples (found on coral tubes in Safe Shallows), 1 acid mushroom (Safe Shallows). Plus basic titanium.

Step 3: Craft the computer chip

Fabricator → Electronics → Computer Chip. Requires: 1 gold + 2 table coral samples + 1 copper. This is the most complex sub-component.

Step 4: Craft the wiring kit

Fabricator → Electronics → Wiring Kit. Requires: 2 silver + 1 copper. Silver may require deeper dives — check sandstone outcrops near the Kelp Forest edge.

Step 5: Craft the Habitat Builder

Fabricator → Equipment → Habitat Builder. Requires: 1 computer chip + 1 wiring kit + 1 battery. Once crafted, equip it to start building. Place a base compartment (2 titanium), hatch (1 titanium + 1 glass), and solar panel (1 titanium + 1 copper + 1 quartz).

FAQ

Frequently Asked Questions

Where exactly are Habitat Builder fragments?

Near small wrecks in the Safe Shallows and Kelp Forest border. Look on the seafloor around debris. If you can't find them, swim further along the biome border.

How do I get silver for the wiring kit?

Silver comes from sandstone outcrops, which spawn slightly deeper than limestone. Check the Kelp Forest edge and small cave entrances.

What should I build first with the Habitat Builder?

A single compartment (2 titanium), a hatch (1 titanium + 1 glass), a solar panel (1 titanium + 1 copper + 1 quartz), and a fabricator inside.
