Habitat Builder Guide

The Habitat Builder unlocks your first base. Reserve its materials before making spare tools, then choose a site with room for the first room, storage and solar power.

Quick answer: Complete two Habitat Builder scans at the Welcome Center entrance and lower cave. Craft it with 2 Titanium, 1 Glass, 1 Basic Battery and 1 Copper Wire at the Fabricator, then build a powered starter room.

Base Building guide
Step 1

Bring a Basic Battery to the Welcome Center

Powering the facility is part of the same early route that leads to Bio Lab and base-building progress.

Step 2

Scan both Habitat Builder tools

Scan both Habitat Builder fragments on the Welcome Center route.

Step 3

Reserve starter materials

Titanium, Glass, Copper Wire, and Basic Battery planning overlap here; do not spend every Copper piece on spare batteries first.

Step 4

Build small and powered

A useful first base is storage, power, Fabricator access, and safe oxygen returns before decoration.
