you live in a zombie apocalypse world

some zombies are normal with no special abilities

but some zombies can mutate and get special abilities like, wall climbing, super speed, super strength or abnormal growth

And some mutate wrong and grow extra limbs or bigger select body parts

you have, a pistol, a knife, i can of food, and some antibiotics

Your walking through the forest when a zombie jumps out a bush

Zombie:"grrrr"
