You can get further... at the end of a round keep a zombie at the window and someone repairing it as it breaks it down. This will allow you to get ammo and that sort of stuff. Also, if you want to get to a high round buy the Bowie Knife and when you run out of ammo, knife them (it helps to have the Ballistic Knife).
