Pack-a-Punch Machine

''"Friends, neighbors, ladies, gentlemen, if you're feelin' underpowered, I'll help you make amends. Just stick your weapon in the slot, and let it change your luck. Few things in life are guaranteed, but I promise this won't suck: Punch you're fists into the air and raise a rebel yell! There's lots of bad'ns out there you need to send to hell! With Pack-A-Punch, I have a hunch, all your problems will be gone, but if you end up on the ground, sing a country western song. Pack-A-Punch (Everybody)! Pack-A-Punch (Yee-haa)! Pack-A-Punch! Pack-A Punch! Pack-A-Punch (Everybody)! Pack-A-Punch! Pack-A-Punch(YEE-HAA!!!)Pack-A-Punch (WAA-HHAAAW)!"

- Pack-A-Punch jingle  The Pack-a-Punch Machine is an in-game utility for the Nazi Zombies map "Der Riese" and Call of Duty: Black Ops'' zombie mode. This utility is much like the Mystery Box or the Perk-a-Cola machines. The Pack-a-Punch Machine allows upgrades to the majority of the weapons found in the zombie level. The machine also changes the names of weapons, as well as putting elaborate engravings on them.

In Kino der Toten, It is accessed by turning on the power, then linking the teleport pad on the stage to the mainframe in the foyer. After this is done, the player has the option to teleport on the pad on the stage. The teleport is free and will take the player to a box above the theater. The machine is considerably less fancy than it is in Der Riese.

In Five, the Pack-A-Punch Machine is accessed by changing the DEFCON level to 5 by hitting separate switches. Once that is done, a "Panic Room" is accessible by going to any teleporter and the Pack-a-Punch Machine is in there.thumb|300px|right|Pack A Punch Song

Effects on weapons in World at War
NOTE: When Pack-a-Punched, most weapons produce purple-red muzzle flash and a strange firing sound.

Trivia

 * Above the Pack-a-Punch Machine, there are two depictions of a Ray Gun, one with a 'flaccid' barrel and the other with an 'erect' barrel.
 * Any weapon which can be purchased off the wall can sell players ammo for that weapon once upgraded for 4500 points.
 * There is also a picture under the machine. The picture is a no symbol (a red circle with a diagonal slash inside) with a hand inside of the circle; indicating that you should be careful not to get your hand caught when putting your gun into the machine. This is similar to the ball return machine at a bowling alley.
 * When a weapon is upgraded in the Pack-a-Punch Machine, only the metallic parts and the magazine are engraved with the markings, and not the wooden parts of the weapon. This is easily attested by the Gewehr 43, and the M1 Garand. This is similar to how the camouflages of Call of Duty 4: Modern Warfare would also only cover the metal/polymer parts of weapons. However, the PPSh-41's wooden grip is made metallic, but not engraved.
 * The Pack-A-Punch also gives the player's weapon full ammo, so a gun with no ammo can be upgraded and come out with maximum ammo.
 * When a weapon is being upgraded a small red flag that says "Please Wait" rises on the right side of the Ray Gun depictions, above the machine.
 * When a weapon is upgraded in Pack-a-Punch, a small jingle will play like Perk-a-Cola machines and at the end, there's a wolf-man howl after the end of the jingle.
 * The character always cracks their knuckles, which is a reference to punching somebody like Pack-a-Punch, as they wait for their weapon to be upgraded. They may also do this because of the thought of not having a gun to kill zombies with or if the outcome of the new weapon is good or not.
 * The Wunderwaffe DG-2 has, like most other guns, a red lightning bolt when fired but after a successful hit on a zombie or dog the bolt turns light blue again.
 * Sometimes, the player's character will sing a Perk-a-Cola jingle while waiting for their gun to be upgraded. Tank Dempsey sings part of the Juggernog jingle, Nikolai the Quick Revive, Richtofen the Double Tap , and Takeo does not sing.
 * The Pack-A-Punch is similar to the perks Stopping Power and Bandolier, depending on the weapon. It can also be similar to the attachments of FMJ and Extended Mags or even a Red Dot Sight, Dual Mags and a Speed Reloader in Black Ops .
 * In the French version of the game, the names of the guns will remain the same; the same happens with the Spanish and Italian versions.
 * If a weapon is left in the Pack A Punch too long, a timer will start. When the timer ends, an alarm will sound and the gun will be lost.
 * When upgrading the .357 Magnum, the Speed Reloader will have the same elaborate markings as the gun, even though the speed reloader was not visibly put into the machine.
 * An extremely rare glitch on the PC is that you can knife open the Pack-A-Punch machine door. The way to do it is to have three players. On a dog round, gather up to doors. Let one player squeeze very close to the doors and get downed by a Hellhound. They should be in knifing range of the doors. They should start knifing the doors while someone revives them. When they get on their feet, the doors should be able to open. Note: to do this, no teleporters can be linked. If even one teleporter is linked, the glitch will not work. The Bowie Knife doesn't work, either.
 * A more powerful version of the C-3000 can be found via Console commands on the PC. It is called the Holy Pistol.
 * The 115 in L115, while also referring to the element 115, may also refer to the sniper rifle L115A3, another sniper rifle used by the British Army, as well as the L96A1.
 * In Kino der Toten, the clock behind the Pack-a-Punch machine is counting down to when the players will be teleported back out of the pack a punch room.
 * Many of the Black Ops weapons reference one of two things: element 115 or the normal name's opposite (IE, "Hades", which is commonly believed to be the Greek guardian god of the underworld, as opposed to "Olympia", which is the Greek mountain of the gods or Heaven.)
 * When you pack a punch a gun the bullets/rays will turn red.
 * The FN FAL can be seen as "EFFIN FAIL", while the EPC WN is supposed to look like "EPIC WIN".
 * The Pack-a-Punch is thought to be powered by Ununpentium because of the "Panic Room" in Five asking for '115 Clearance Required'. 115 being Element 115 or Ununpentium.
 * When upgrading your weapon, a flag will come up on the machine that says "Please Wait." This flag can be found in the Black Ops multiplayer map "Firing Range" in the area of the wooden building that slightly resembles the training area of Call of Duty 4. While walking up the staircase of this building, if you turn around, you will see this flag on the far left on the area where a wall or roof should be.
 * If the M1 Garand w/ Rifle Grenade is Pack-A-Punched while the player is still in Rifle Grenade mode, the Pack-A-Punched M1 Garand will also be named "The Imploder" along with the Pack-A-Punched Rifle Grenade instead of "M1000."
 * Every map containing the Pack-A-Punch always require the power and a teleporter in some form to access it. In Der Riese the power is needed to activate the teleporters and the teleporters are needed to open it. In Kino Der Toten the power is needed to access the teleported and the teleporter is needed to teleport to the Pack-A-Punch. And in Five the power is needed to access the death-cons and the teleporter is needed to get into the Pack-A-Punch room.
