The Death Machine can be found in the Zombies maps "Five", Ascension, Dead Ops Arcade, Call of the Dead and Moon as a power-up. In power-up form, it appears as a three-dimensional model of the icon for the Rapid Fire attachment. It is easily identifiable, casting a blue glow instead of the usual green. The Death Machine lasts 30 seconds with unlimited ammo, and firing it constantly will not affect its duration. It does a great amount of damage to Zombies at early to medium rounds as well as the Pentagon Thief, who can also steal it. It is fairly ineffective at high rounds (40+), though. It must be noted that one can't upgrade it, buy another gun, or revive teammates while using it. The player can still repair broken barriers, open doors, or clear debris. When the power-up is almost over, a low ammo quote will be heard and the icon will start flashing.
