Objective:

You are the overseer. WARDEN's drones do the work: mark rock to dig, place rooms in dug-out space with solid floor, and decrypt blueprints with Data.

Power short? Brownout slows everything. Chambers wider than 8 need pillars. Recycling beats mining. Nothing is ever lost for good.

Shift-drag to dig with priority. Double-click a vein to mark all of it. Ctrl+Z undoes marking. Shift-click keeps placing. C centres on the pod. Click a ◎ console line to see where it happened.

Rich lodes (bright, chunky deposits) don't dig away. Mark one once and drones keep working it, after other digging, while there's room in storage. When its reserve runs out it still gives, four times slower.

DRONES (L) chooses each drone's kit once you've researched more than one. The deep-core drill needs no kit: mark bedrock with DIG. Cameras and missile silos go in the surface rock, top row at the skyline, and cut their own way down.
