Pre-order Call of Duty: Ghosts for free map

Activision has confirmed that those who pre-order Call of Duty: Ghosts from participating retailers will get a 'dynamic' multiplayer map at launch.

The map is called Free Fall, and it introduces 'dynamic map events' that will see environments change as the game progresses.

"Free Fall drops players into a shattered skyscraper on the brink of collapse," reads the official description.

"Sideways staircases climb into the night sky, elevator shafts run along the ground, and what were once windows now form a terrifying glass floor, hundreds of feet above the city streets."

Participating retailers are yet to be confirmed, but the promotion is occurring worldwide.

Call of Duty: Ghosts launches 5 November for Xbox 360, PlayStation 3 and PC. Next-gen versions will follow later in the year.
