i think treyarch should make a game with just their zombies on it that way there would be so many maps to play and also they can take all these ideas and put them into different maps and by that i mean of course wunder weapons that people came up with maybe some normal weapons in different maps (different time line?) and zombie ideas!
respond to this if you agree and want treyarch to go through with this! 
Lastly i think to allow the production of this game to not take as long they could take all currently made zombie maps into the game but also have them done up in graphics glitches checked and add in extra shizz like perk machines they have considered from peoples ideas and much more and along with them have about 6 new maps made 
please comment if you want this to happen so so bad and add to it and if not then give a thousand like if not more if you want this to happen i definetly DO!!!
