these are the types of zombies okay and here is the story behind how the nazi zombies got there:it is area 51 the survivors from project der riese brought back living test samples the scientists were the first to be infected after trying to copys from dead american soldiers killed in vietnam after they infected the scienctists they infected the office workers than while area 51 was locked down sog came in to stop the threat at the source. and because they said that even the co-op modes had thier own customizaition that means that you buy the atachments for the gun first then when you get the gun in the game the atachment is already placed on your gun and you buy the atachments with something i like to call zombie points
