Grandpa Peco was once a famous miner and he is now willing to share the location of his secret stash of treasure with you. But the problem is that they are buried deep underground, more than 100 of yards. Join the grandson and his friend, the Mad Digger, on a digging expedition adventure to retrieve golds, diamonds, and other precious stones. The goal is to dig deeper and deeper until you find the treasure, but it is not as easy as it sounds. There are limited supply of oxygen as you go deeper and expensive equipments required. Slowly upgrade your equipement and oxygen level over time, and also use explosive such as grenades and dynamite to expedite your endeavour.
Good Luck and Have Fun.
