FORUMS_

I've been thinking, there are a lot of vids of zombies and other stuff, and people forget that treyarch could be watching. They see that people develop strategies that work out in every map other. They want us to be addicted to it, so the only way is that they make maps harder, when you loose and you don't want to quit you keep playing. So who knows, from looking into BO zombies, maybe they'll change things way differently, just like the multiplayer engine thing, the ideas of different modes, ect.They want us to keep guessing, people who follow  the story can't know what to wxpect, people who play and know how zombies work can also expect something different.
