Terrum DeepDrill

Terrum DeepDrill is a single-player underground mining game. Drill through rock, haul ore, upgrade your rig, and push deeper. Fuel, heat, hull, and cargo all matter — empty in the hole and you walk home. Buy drills, travel between dig sites, and spend Terra Credits on maps and gear.
