There needs to be areas of the map where military battles happened and failed. Burnt out buildings, explosion craters, destroyed military vehicles, things like that. Also, the same but on a smaller scale like a neighborhood tried to fortify a few houses and made a last stand and failed. Attacked cars, a burnt down house that had a metal fence around it. Things that show that we're was a battle at the begining that lead to the game it is now. Right now, it's like a wave swept over the world in one second and turned everyone into a zombie, except you.
Pretty much, I want to turn the corner and see the outcome of the Battle at Yonkers.
