I've always wanted a zombie game with a city. Why not a map that would include a center city one that could include a school, hospital, and retail park. Maybe outside of it is American suburbia. I had been thinking of a city that's not too big like maybe one like lockport, NY it's small and would have some interesting POI to explore. I think a new map in general is what people want and with the heartland it was a nice refresher from the three maps I'd have played many times before.
