You will have in this game leading a troop of miners through a career. At least initially, as you will soon find yourself at the head of two troops extracting different types of minerals, dying in contact with other, much more troops, and ... There is almost new at each level, we do not mind! A puzzle game, patience and maybe memory (try to remember where you have driven in your minor lava, where they were crushed by a drill, or cut by a grinder ... it you avoid starting the test after;)) It even becomes quickly hooked!
