ECHO DRIVE

The surface went silent. Everyone left for orbit. The machines were never told to stop.

You remote-pilot an old work unit through five zones the humans left behind — a plant, a mine, a harbor, an arsenal and the base of the orbital elevator. Each one is still running its last order, and each one treats you as a foreign body.

Tear parts from the wreckage, rebuild your machine, and push deeper. Bring your cargo home through a descent hatch, or lose it all when your signal dies.
