Pack-a-Punch Machine

The Pack-a-Punch Machine allows weapons to be upgraded to better versions of themselves. The machine typically changes the weapon's name, adds one or more attachments, increases the damage output, increases the magazine capacity and makes the firing sound higher pitched accompanied by a red/purple muzzle flash. The weapon also notably gains a bizarre camouflage to accent the changes done to it. The camouflage changes by game, and in Call of Duty: Black Ops II, Black Ops III, Infinite Warfare and Black Ops 4, by map as well. Infinite Warfare is unique in that it has two camos per map, with one for when the weapon is Pack a Punched and then the second for when it is upgraded further.
