there is also another way to get multi guns if you can remember how to do it on the first zombi map its the same way have a team mate go down next to the mystery box and then hit square to open it wait a second or two then start reviving him and about half way through if done correctly you should see press square to trade guns when this appears release square and then quickly hit it back if done correctly you should have three guns there are also vids on youtube showing how to do this if you have any questions you can msg me on psn alabama_basterds
