Aims and Objectives
In adventure mode, you don't immediately set off knowing your aim. You get told in your first transmission that you should dig down deeper to find minerals to bring back to the surface; the deeper you go, the more money you can get from minerals. However, after this things start to get a little wierd, and you find yourself fighting for your life as you get very deep down... Saying anything more at this point would spoil the ending.
