The Chopper

"RAR! BRAR BRAR!"

 is a machine gun that can be dropped by Motorhead in The Secret Armory of General Knoxx. It sports a ridiculous clip size, very high rate of fire, low accuracy, and the ability to fire four bullets at a time, much like the Anarchy line of SMGs. It can be devastating, but it can also chew through your entire ammo stockpile in a matter of seconds.
