Deep Drill

Pilot a compact underground drilling rig and push deeper into a layered world of unstable rock, glowing mineral faults, geothermal chambers and forgotten machinery. Choose each drill direction, manage fuel, heat, hull, coolant and cargo, then decide when to return safely with the haul. Descend through five visually distinct regions, recover twelve mineral types, uncover ancient objects, complete field contracts and invest extraction credits into seven persistent rig upgrades. Deep Drill works fully offline, saves progress locally, and contains no ads, accounts, subscriptions or online services.
