Subnautica 2 Habitat Builder: Unlock Location and First Base Build

The Habitat Builder is unlocked by scanning 2 fragments at the Welcome Center (85m SE of the Lifepod) — one in an outside crate, one in a hole below the structure. After unlocking, craft it with 1 System Chip + 1 Basic Battery. The System Chip requires 1 Wiring Kit + 2 Quartz. The Wiring Kit needs 1 Silver + 1 Copper Wire. This is the most involved early recipe chain on Proteus so plan your material runs carefully.

Guide Steps

Step 1: Find the Welcome Center

The Welcome Center is approximately 85 meters southeast of your Lifepod in the Shallows. Before heading there, craft a Basic Battery (2 Copper Ore + 1 Acidic Raion Pouch) to power the facility. Swim southeast from the Lifepod keeping the seabed in view. The Welcome Center is the only major structure in this area, identifiable by its angular metallic architecture.

Step 2: Scan both Habitat Builder fragments

There are exactly 2 Habitat Builder fragments at the Welcome Center. Fragment 1 is inside an open crate on the exterior of the structure — approach from above. Fragment 2 is at the bottom of a hole directly below the Welcome Center. Swim down through the opening under the structure. Both fragments are within 20 meters of each other. After scanning both, the blueprint is unlocked. These are the only two fragments needed — no random wreck searching.

Step 3: Craft the component chain

The Habitat Builder requires 1 System Chip + 1 Basic Battery. The System Chip needs 1 Wiring Kit + 2 Quartz. The Wiring Kit needs 1 Silver + 1 Copper Wire (Copper Wire = 2 Copper Ore). So the full material chain is: 2 Copper Ore for the Copper Wire that goes into the Wiring Kit plus 1 Silver for the Wiring Kit plus 2 Quartz for the System Chip plus the battery materials. Collect Silver from caves in the Shallows or Plateaus biomes.

Step 4: Craft the Habitat Builder

Fabricator then Equipment then Habitat Builder. Requires: 1 System Chip + 1 Basic Battery. Once crafted, equip it to enter build mode. The Habitat Builder lets you place base modules, power sources, and interior fittings. Each module costs Titanium and other materials shown on the build HUD.

Step 5: Build your first base compartment

Start simple. Place one I-compartment (2 Titanium), a hatch on top (1 Titanium + 1 Glass), and a Solar Panel on the exterior (2 Titanium + 1 Copper Ore + 1 Quartz). Inside, place a Fabricator (2 Titanium + 1 Copper Ore) and 1-2 Lockers (1 Titanium each). Build near the Shallows border with the Plateaus biome for easy access to Silver caves and deeper exploration routes.

FAQ

Frequently Asked Questions

Where exactly do I scan Habitat Builder fragments?

At the Welcome Center, 85 meters southeast of your Lifepod. One fragment is in an outside crate on the structure. The second is in a hole below the Welcome Center. Scan both to unlock.

How do I get Silver for the Wiring Kit on Proteus?

Silver is found in caves within the Shallows and Plateaus biomes. Unlike Subnautica 1, Silver does not come from sandstone outcrops — search cave walls and crevices in deeper areas.

What is the full material chain for the Habitat Builder?

2 Copper Ore + 1 Silver + 2 Quartz + battery materials (2 Copper Ore + 1 Acidic Raion Pouch). The path is: Copper Ore to Copper Wire, Copper Wire + Silver to Wiring Kit, Wiring Kit + Quartz to System Chip, System Chip + Battery to Habitat Builder.
