DRW Air Horn

The  is a combo weapon in Dead Rising 2 and Dead Rising 2: Case Zero, made by combining these two items:
 * 1)  Spray Paint
 * 2) Pylon

The Air Horn is a combo weapon that acts as a really loud horn (so loud that Chuck has to cover one ear when he uses it) that, when used for an extended time against a crowd of zombies, will cause their heads to explode. It can be made in Dead Rising 2 and Dead Rising 2: Case Zero. 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.

The Air Horn is surprisingly effective against looters, since it killing them immediately.

Trivia

 * Despite the combo card naming one specific type, any can of spray paint can be used to create this weapon.
