I Don' Freaking Know Man Get Off The Freaking Xbox Or PS3 and go read a book man freaking Video Games.
There is no sure-fire way to get the MG42, but your best shot is with the mystery box.
you can't, normally its on the wall for 1000 points and you can not get weapons from the mystery box that are also on the walls
There can only be 24 zombies at one time aka the waves.
you have to find the fingerbox
You don't. The random box chooses a weapon at random every time. Hence the name "Mystery box" or "Random Box"
Yes it is but it takes a long time to get very high
You can't, it doesn't matter what map it is, the Mystery Box order in which gun it gives you is completely randomized.
You can only carry two weapons at a time.
yes
This might sound weird but there is NO ENDING to nazi zombies it keeps going and going. By the the time you reach 2417 you will move all the way down to the ledge boards so there is no ending no matter WHAT!
4 online two, split-screen
A maximum of 24 zombies per player can be on the map at any given time, the number of total zombies however increases every round
