- "Friends, neighbors, ladies, gentlemen, if you're feelin' underpowered, I'll help you make amends. 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 your fists into the air and raise a rebel yell! There's lots of baddies out there you need to send to hell! With Pack-A-Punch, I have a hunch, 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)!"
The Pack-a-Punch Machine is a machine featured in all zombie maps starting with Der Riese and up, not counting Dead Ops Arcade. It is almost always very difficult to use, as in most maps you have to do a difficult task to turn it on and it has a really high price to use, which is 5000 points. It will turn almost any weapon into something far more powerful than the original version
Call of Duty: World at War
The Pack-a-Punch Machine was originally introduced in Der Riese and was unlocked by having all three teleporters connected to the mainframe found in the starting area of the map.
Call of Duty: Black Ops
The Pack-a-Punch Machine returns once again in Black Ops, appearing in Kino der Toten, "Five," Dead Ops Arcade (as a Power-Up), Ascension, Call of the Dead, Shangri-La, and Moon.
Call of Duty: Black Ops II
The Pack-a-Punch Machine reappears in Nuketown Zombies and Town in Green Run. In Black Ops II, the players are able to Pack-a-Punch their weapons a second time for 2000 points and will get a different attachment on their weapon. However, they will not receive more ammo or any other upgrades.
The Pack-a-Punch Machine also appears in numerous fanon creations as well.
