Upgraded weapons/Black Ops III

Trivia

 * Some upgraded weapons start with slightly less reserve ammo than their max amount: Marshal 16 Dual Wield (208+6/6), NX ShadowClaw Dual Wield (144+12/12) and GKZ-45 Mk3 (210+5/30).
 * Similarly to Call of Duty: Black Ops II, the camouflage for the Pack-a-Punched weapon varies depending on the map:
 * In Shadows of Evil, the camo is similar to that of Mob of the Dead in that it is made of apparent cracks filled with lava forming the symbol for human transmutation. This camo was introduced as a normal camo called Ritual Camouflage.
 * In The Giant, the camo features a golden/silver scheme, with the Iron Cross symbol prominent. This camo was introduced as a normal camo called Etching Camouflage.
 * In Der Eisendrache, the camo has a Dark Matter Camouflage like appearance but is randomly selected between red, yellow, green, blue, and pink/light purple colorings.
 * In Zetsubou No Shima, the camo features glowing green vines with a yellow pulse animation.
 * When the player Pack-a-Punches a weapon, it gains two visual attachments, Extended Mags and FMJ. As shotguns do not have FMJ, they only get Extended Mags.
 * The Pack-a-Punched VMP and Drakon have the Extended Mags model and reloading animations, even though they don't get a higher magazine capacity when upgraded.
 * Pack-a-Punched weapons have a chance of acquiring the FMJ and/or Extended Mags Legendary attachment. You can also acquire them via Re-Pack-a-Punching a gun.
