You mean the Mystery Box and in the Nintendo DS the Mystery Locker, Random Box or even The Box that appears in all Zombie maps in Black Ops and World at War. Read all about it on the related Mystery Box Link
Locations are in different places on the different maps and in several in some of the maps. It's best to look at the related link that also lists the weapons available in the different maps
you get it from the random weapon box by luck.
You don't. The random box chooses a weapon at random every time. Hence the name "Mystery box" or "Random Box"
It is only available as a random mystery box weapon. Use the box until you get it.
the only way to get a FREE pack a punch is to be on the map moon and get a QED in the random box - if you throw it it has a chance of dropping a random weapon, pack a punched or not
mate it's not possible......sorry
The Thunder gun can be found hiding in the "mystery box". Buy the box for 950 points and it gives you a random weapon just hope you get it. There is also another weapon only found in the mystery box called the Ray gun.
It is obtainable through a purchase of the random weapon box (mystery box)
You can usually find it in the random weapon box.
from the random box
Anywhere, its the "Random Box" haha, just look around for it.
You must first find the monkey bomb in the random weapon box. Once you have them, press L2 or the equivalent on xbox (the one to throw a flashbang) and your character will throw a monkey bomb.
