The description states that the map has been redesigned for the new movement system in Black Ops 3.
Get the bonus NUK3TOWN map. This map, which is among the fan favorites, was completely redesigned to highlight the new chained motion system based on momentum of Treyarch, providing battles full of adrenaline.
