Habitat Builder Guide

Habitat Builder is a core item page because every base-building search eventually asks the same three things: where to scan it, what to reserve for the recipe, and where to place the first powered base.

Quick answer: Habitat Builder unlocks base building. Public guides point to two scans at the Welcome Center route, then a craft chain involving starter materials such as Titanium, Glass, Copper Wire, and Basic Battery. Use live station text for exact counts.

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

Public guides describe two scan sources around 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.
