Terrum DeepDrill

Terrum DeepDrill is a single-player drilling game in a 2.5D side view. Terrum Corp owns your debt and calls it a contract. Win tenders against rival firms, drill down through rock, ore and trouble, and haul out enough to stay ahead of the bill.

Win the tender

Every tender comes with test boreholes: cores sunk into the exact ground you would dig, logging its rock layers, ore veins, gas pockets and lava. Then the site goes to a live auction where the highest bid wins, and all the ore you dig there is yours. Three rival firms raise against you every few seconds, hold a grudge against whoever beat them last time and snipe the best sites at dawn. Bid too high and the ground won't pay you back.

Dig deeper

Drill in real time and keep an eye on fuel, heat, hull and cargo. Four levels take you from the first claim to the Red Canyon, the Glacier and the volcano.

12 kinds of ore, from coal and iron to platinum, diamond, uranium and meteorite

Gas pockets, lava, buried artifacts and fossils

Haul it up the shaft tower, then sell it at the depot and ship it by truck, ship or plane

Three rigs

Start in the Rust-Bucket V1. Earn the Iron Golem Mk-II. Bring down the Mega-Quake 9000. Each rig balances fuel, cargo, hull and power differently.

The mine fights back

On the surface, lightning storms, blizzards and ashfall roll in, and thieves raid your depot.

Below ground you face earthquakes, cave-ins, methane explosions, floods, overheating and rising magma. Plan for it or lose the rig.

Build the base

Upgrade your station with security walls, fences, turrets, a teleport pad and insurance. Find shelters in the dark to refuel, repair and stash cargo.

Run a crew

Hire operators and send crew rigs to work up to three contracts at once. Mix drills from your fleet on one site: each crew digs its own strip under the same rules you play by, rides the mine shaft's cage, comes home with a full hold, unloads at the depot and buys fuel, repairs and upgrades from the company wallet. Hauler workers, crate loaders and drones carry the floor crates to the depot. Wages are due every dawn, and a crew you can't pay will quit.

Three regions, one globe

Start on Tasmania's West Coast, then fly to the Pilbara Red Desert and the Volcanic Archipelago. Each region has its own ground, weather and tenders.

The door below

A voice on the radio called M. keeps you company. Old miners talked about a door below. Something hums down there, and it isn't the lava.
