In this cool game you have to collect minerals on Mars and bring them back to the surface for processing. The deeper you dig, the more valuable the minerals you will encounter. You have been given a basic mining machine to get started with. Control your pod using the arrow keys or,if it is more comfortable,than w.a.s.d keys. Your drill will deploy automatically if you move into diggable material beside or below you-remember,you cannot drill straight up.
