An arcade style flash-based mining game. Navigate the dangers of Martian soil, complete with hidden gas pockets, earthquakes, and other surprises. Purchase powerful upgrades for your Mining Pod with the fruits of your labor. Compare high scores with friends to see who the champion really is. When you've finished the game, challenge more difficult gameplay modes.

You arrive on mars, penny-less but with the bare minimum digging equipment to try and make a living. Gather resources to buy upgrades, and dig down… but be careful to survive the fuel, heat, and other dangers. The deeper you go the more valuable the resources, but beware the dangers!
