Modern Warfare 3 trailer demos co-op 'Survival'

A new trailer for Call of Duty: Modern Warfare 3 has been released, featuring a look at the game's co-operative "Survival" mode.

Like other Horde-like modes, the game pits players against increasingly difficult waves of enemies; however, players also gain access to new weapons, armor, and support as the mode progresses. It's certainly one of the elements that has me excited for the upcoming game... that is until Attack Dogs strapped with explosives enter the picture. Does the 'annoying factor' of attack dogs really need to be dialed up to eleven?
