Upgraded weapons

The following is a list of the Pack-A-Punch weapons and the differences between them and the normal versions of the weapon.

General

 * Some Pack-a-Punch weapons have the number 115 in their name, a reference to Ununpentium.
 * A few Pack-a-Punch weapons have numbers that stand for letters, a reference to "leet-speak", a symbolic alphabet that uses a combination of ASCII characters to stand for letters (5 = S, 3 = E, |-| = H, etc.).
 * Weapons from World at War will have a certain PaP camo scheme, while the guns from Black Ops have a different camo scheme.
 * Some weapons appear to have a rusted look when upgraded in Black Ops.

Weapons

 * In Der Riese it is possible to Pack-a-Punch a Mosin-Nagant, a Sawed-Off Double-Barreled Shotgun w/ Grip (The Smuff Box) and a Arisaka (The Eviscerator) through modding (which were cut from the final game).
 * Sally is a reference to the M1911 pistol on the cover of Call of Duty: Black Ops.
