The Air Horn is a combo weapon that can be made in Dead Rising 2, Dead Rising 2: Case Zero and Dead Rising 2: Off the Record. It is a can of spray paint attached to a pylon. Using it on nearby zombies will disorient them, grabbing their ears in pain while prolonged exposure will cause their heads to explode. It can also can be used as a "lure" to attract zombies away from survivors. However, the actual effective killing range of the air horn is very limited.
