You start digging around the hand, helping it get free. More and more arm is exposed and the other hand has broken out and you help it hatch above the ground. Soon a head pops out. A ghastly rotted head and the corpse is trying to bite you. But its still buried to the torso. Nicolm is beside you now snapping pictures. He then pulls out a .32 caliber hand gun from his back pack. He deftly puts one bullet point blank into its torso and the corpse is still again. "I have seen this sorta of thing before", Nicolm tells you "In my home country. Just shoot them in the head and they stop moving. The are the walking dead, powered by some unknown thing to rise and eat the flesh of the living. Whatever happens don't let them bite you or you will die and become one of them". Nicolm turns out to be some sort of an expert about dealing with zombies. He has several weapons in his trunk. you select a shotgun and a handgun. Nicolm has an axe and a sledge hammer. The two of you set about crushing skulls in until every zombie trying to dig free of the earth is destroyed. Good work. You and Nicolm make a great team. Looks like you two will probably survive this outbreak.
