Thundergun

Overview
The Thundergun is a weapon featured in the Dead Ops mode and zombie mode of Call of Duty: Black Ops. It is a cannon-shaped weapon that fires directional blasts of atrociously strong wind. It appears to be able to kill large numbers of zombies with a single shot, sending them flying backwards. Those who are not killed by the wind blast are thrown backwards. The Thundergun holds two rounds in a magazine, and holds twelve reserve rounds. For some reason, the weapon cannot be reloaded manually. It can only be reloaded when both shots are expunged. Its Pack-a-Punched form is called the Zeus Cannon.

Trivia

 * When upgraded, it becomes the Zeus Cannon. This is an obvious reference to the Greek god Zeus, the God of Sky and Thunder.
 * The gun has "Osterezheniye" written on its side, which is incorrect russian translation of "Warning".
 * When Richtofen gets the Thundergun he suggests that it could be the "DG-3".
 * If some zombies are not hit directly with the wind, it is possible to see them get back up slowly.
 * The Thundergun can also be a reference to the weapon that the main character from District 9 uses to escape his african captors.
 * The Thundergun is the only weapon so far in game that cannot be reloaded without finishing the held ammo.
