No, you can't upgrade a gun more than once.
Yes
yes nazi zombies does have split screen i only know how to get you to split screen zombies on black ops so if you have world at war then i dont know but anyways once your at the main menu go to zombie mode then split screen and there you have zombies on split screen!
yes but the graphics suck and when you get hit once your dead
Yes because humans are way much more better and smarter than zombies. Zombies tried to kill humans with it's teeth but humans can run much more faster and break the zombies neck.
sorry to say this but you can't, once you press ready you can't turn back.
yes it comes in a care package but its really rare I have gotten it once I have never seen it in zombies tho
you can't become a zombie once you die the game is over and you have the option to play again but again you can not become a zombie
No, for once wolves are real and zombies no. Most people are not so scared of zombies and are way too scared of wolves.
If mw1 means Modern Warfare One or CoD 4 then the answer is you can't. But you can get CoD 4 weapons on the PC version of Nazi Zombies for CoD 5.
In Wii, you unfortantily follow the other settings for the others gaming systems. In order to get Five, you must be Campain in order to unlock it. Once you have beaten the last level it automaticailly takes you there. To get Dead Ops, you have to break out of the chair you are in and find the computer. Once there, you have to type in a code. I dont know it but i will post it once I get it. Have fun! PS: No offence, but it is not caalled Nazi Zombies, it's called Zombies. Kino Der Toten is the only Nazi Zombies arena
Yes you can because my friend rented it once and he brought it over and we played zombies
make your way to the stage. once you get there go to the red curtain and follow it to the other side of the room and you will see the power box
