Trivia

 * Many Pack-a-Punched weapon names are opposites of their unupgraded names (i.e. "Olympia" and "Hades").
 * "LSAT" and "FSIRT" are plays on the words "last" and "first".
 * "FN FAL" can be pronounced as "effin fail", while "EPC WN" is supposed to be pronounced as "epic win". "FAL" and "WN", the shorter weapon names in Black Ops II, simply stand for "fail" and "win".
 * The "M72 LAW" and "M72 Anarchy" are a reference to anarchy being the opposite of law.
 * Some Pack-a-Punched 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.).
 * ".357 Plus 1 K1L-u" is leet for ".357 plus I kill you".
 * "C-3000 b1atch35" is leet for "see 3000 biatches".
 * "F1W" in "F1W Nitrogen Cooled" is leet for "FTW", a common abbreviation for "for the win".

 * "SM1L3R" is leet for "smiler".
 * Some of the Pack-a-Punched weapon names in Call of Duty: Black Ops II Zombies are backronyms of the weapon's original name (i.e. the RPD becomes the "Relativistic Punishment Device" and the MTAR becomes the "Malevolent Taxonomic Anodized Redeemer").
 * "Synthetic Dozen" stands for "Synthetic 12", a backronym of the unupgraded name "S12".
 * "1001 Samurais" is a reference to the weapon's Japanese origin (as Samurais are Japanese fighters) and the popular film "101 Dalmatians".
 * "M1000" and "M1 Garand" stand for 1000 = 1 Grand, which is how players often pronounce the weapon name.

 * "AK74FU2" is "AK74 fuck you too".
 * "Ultra & Violet" is a reference to ultra violet rays.
 * "Python" and "Cobra" are both names of snakes, where a cobra is poisonous unlike a python, and therefore more powerful.

 * The "Infra-dead" in "Hyena Infra-dead" refers to the added Infrared Scope.
 * "V-R11 Lazarus" is a reference to Lazarus, a man believed to have come back from the dead. "V-R11" stands for the Vril, a fictional device with a similar effect. The game has multiple other references to the Vril.
 * Zeus is the ancient Greek god of sky.
 * "SPAZ-24" is a reference to its 24 round magazine. 24 is also 2 times 12, as in "SPAS-12", which could mean 2 times more powerful.
 * Some Pack-a-Punch weapons have the number 115 in their name, a reference to Ununpentium, also known as Element 115, which was related to the creation of the zombies, teleporters and the Wonder Weapons. Also, if one goes to the monitor (after breaking out of the chair at the main menu), one can access a document by Dr. Maxis saying that element 115 can enhance weaponry.
 * It can be said that on Call of Duty: Black Ops Wii, it seems that all the Pack-a-Punched weapons are green except the Porter's X2 Ray Gun which is black and orange, however this may just be a visual or texture glitch.
 * 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 is a swirling tone with a mix of red, green and shining metal covering each weapon or on Mob of the Dead It is a rock camo with glowing magma lines coming throught it
 * Treyarch stated that the Arisaka will be able to be Pack-a-Punched. Since they referred to it as the Type 99 rifle, this has caused many players to believe that the Type 99 machine gun could be Pack-a-Punched.
 * Mustang and Sally is a reference to the song Mustang Sally. On the front of the game's box, the soldier is holding an M1911 that has the word "SALLY" and the number eight in tally marks carved in the side.
 * The Typhoid and Mary is an obvious reference to the actual person Typhoid Mary.
 * The Tokyo and Rose are likely a reference to the actual people nicknamed Tokyo Rose.
 * The Calamity and Jane are likely a reference to the actual person Calamity Jane.
 * Just like the Ray Gun, the Mustang and Sally pushes the user back when fired.
 * The Ray Gun and the Zap Gun Dual Wield are the only Wonder Weapons when Pack-a-Punched have the prefix, Porter's X2.
 * Many Call of Duty: Black Ops guns including the AK47, Kiparis, Stoner63, Skorpion, WA2000, and a removed gun called the Sabertooth were once available in zombies mode with their own pack-a-puched versions, as according to the game files.
 * The Widow Maker is a somewhat common term for something that kills many men.
 * Some of the new weapons in Black Ops II can be Pack-a-Punched more than once, resulting in different attachments.
 * Every map in Call of Duty: Black Ops II Zombies has its own Pack-a-punchcamo.
