After Grandpa Pecos chose to share a key with his grandson? There is a hidden treasure buried somewhere on the former mine. But there is 1 problem. The treasure is located quite deep underground at a depth of over 100 yards! Subsequently the grandson thought about his buddy, the Mad Digger. He is the only one to do it. Your job would be to dig deeper and deeper till you discover the treasure. It is not quite as straightforward as it appears. The oxygen works out with each warrior, you have to extract minerals to increase your tools and equipment and to purchase grenades and dynamite to create the descent quicker.
