anything. Enter the police station and pick up the bullets on the 
desk then head back outside go down the stairs and there will be a 
zombie down there. He is hard to kill but when you do search him 
you will find a key go back in and when you get tothe dark room 
their will be a locker and you can open it and find a new suit 
and gun...
