The Scavenger is a wonder weapon only appearing in the Call of Duty: Black Ops map Call of the Dead. The Scavenger is a bolt-action sniper rifle that fires an explosive bolt, which explodes for massive damage after a short time. The damage is very high, but not infinite. Eventually the weapon will only make crawlers from the blast. The high damage is also incredibly useful for killing George Romero. It holds 3 bolts per magazine, and holds 15 bolts in reserve. In Call of the Dead, the Scavenger can be acquired from the mystery box for 950 points.
The origins of the Scavenger are unknown. However, it can be inferred at least that the upgraded version, the Hyena Infra-Dead, was invented by Dr. Harvey Yena of Group 935.
When placed in the Pack-a-punch machine, the Scavenger is upgraded to the Hyena Infra-Dead. The magazine size is upgraded from 3 to 6, and it will hold up to 30 shots in reserve, doubling the original 15. The damage is doubled, the scope sway is reduced, and the sights become infra-red with variable zoom.
- The Hyena in Hyena Infra-red has two meanings, one referencing the presumed creator, Dr. H. Yena, and the other referencing the original name of the weapon, the Scavenger. Hyenas are known scavenger animals, picking at carcasses already half-eaten by other predators.
