Brick Blaster

The  is a weapon in Call of Duty 4: Modern Warfare that is hidden in the game's code. It can only be obtained by using the command console. When shot, it fires a bullet as well as a cinderblock. Any bricks fired will remain on the map for a short period of time. When equipped, the ammo counter becomes invisible.

Additionally, when in third person and aiming down the sights, the character will walk in an odd slouching motion, which is not seen anywhere else in the game.
