Gather resources and buy upgrades to dig as far as you can. You have to dig ores and sell them to earn cash which you use to buy fuel, digger upgrades, explosives, and other supplies. You can only sell ore and buy items at the surface. If you run out of fuel, your digger explodes and you die (game over). There are more valuable (and heavier) ores as you go deeper into the mine. There are several types of alien artifacts which are of considerable value and appear randomly throughout the mine (below 950 feet).
