Journey to the center of the Earth, moon or on a martian expedition with the Clockwork Digger. This four man craft sports tank like treads on its surfaces, with a mighty and powerful digging/drilling engine. Inside, find a fuel storage room, then into the main passenger bay with steampunk readouts, access to the clockwork engine, and four seats.
Digger has two drill parts with "turn" dials. Also the back hatch has an "open" dial so you can open/close the back hatch.
