you have to be on der riese and activate all teleporters and go back to the start off the map and pay 5000 points to put a weapon in
No.
It means you can upgrade your guns.
Go up into the projector room and at the back of the room there is a upgrade machine....youhave to pay 5000
no you cant get four guns in nazi zombies de rise it is purely impossible. WRONG!! you can do the multiple gun glitch...alot of people do it and it has not been patched...look it up on youtube

no
Yes! what you have to do is when you have all your guns like 1st upgraded one then second upgrade and when you have got the kark and go buy a new weapon from the box, you have to save Betty an when the round is nearly over make a crawler and run to the pack-a-punch and put your gun in and do the exact same to get three guns put it in and then grab a Betty and when the gun comes out you then quickly select Bettie's put them down and grab the gun :) :)
i have no idea, but someone else said u could
All i can say is that there is more than 98 levels so you really have to get two good guns
Nazi zombies is renamed COD Zombies now.
All right now the best gun 4 nazi zombies are 1st the MG/barracoda. Its a big gun shoots faster than the browning. And its a bamf duuhhh. 2nd the ray gun, upgrade it though. and after a dog round u get max amo! These weapons ROCK my friend and I got to level 35; with these weapons and stay were the mystery box is up on the cat walk. put bouncing bettys in the back of you and you will last 4 ALONG time.
If you beat the game you can get nazi zombies
