"where do i get the chain saw like in the comercial or is that fake there really isnt 1 help me out" Yeah, there are chainsaws in this game. Go into the hardware store where you fight the psycho Cliff, and you'll see a bunch of chainsaws lying on the floor. It may be hard to rev it in there beacause there's so much zombies in there.

Isn't boss of bosses a one time event?
