Subterra: Deep Drill

Pilot a chunky tracked drill mech on a frontier mining colony. Descend, mine, return, upgrade, descend deeper — and the cycle gets more dangerous and more rewarding the further you push.

Cut through layered biomes from rich topsoil to glowing crystal caverns to molten magma depths. Sell rare ores at the surface outpost to upgrade your drill bit, fuel tank, cargo bay, and hull plating.

Hidden somewhere beneath the rock are sealed chambers where ancient guardians protect powerful gear. Heat shields, crystal drills, jetpack thrusters — the kind of upgrade that lets you reach a depth no other miner has ever survived.

How deep can you go before your fuel runs out?
