 * All Pack-a-Punched weapons have a certain Pack-a-Punch camouflage scheme. In Call of Duty: World at War, the camouflage is a metallic tone, while in Call of Duty: Black Ops, the camouflage is more of a machinery tone with what looks like circuitry covering it, and in Call of Duty: Black Ops II,  the camouflage depends on the map that is being played:
