Already one of the year's most anticipated titles, Activision and Infinity Ward have upped the ante to entice more pre-orders for Call of Duty: Ghosts by offering a free multiplayer map at select retailers.

Free Fall takes place in a crumbling skyscraper, which is already toppling over. The glass windows are now the floor. The elevator shafts run horizontal instead of vertical, and staircases lead to nowhere but the night sky. As the multiplayer match progresses, the building will continue to fall, dynamically changing the landscape of the battlefield. Sight-lines and chokepoints will alter in real-time, giving Free Fall a life of its own.

"Dynamic map events change the way players approach the game, and Free Fall does a great job illustrating this new mechanic," said Mark Rubin, executive producer at Infinity Ward. "As the match progresses, the geometry of the world continues to change and players need to adjust on the fly or else. It's a really fun new feature that adds layers of strategy and constantly evolving gameplay options for players."

The map will be included with Ghosts when it arrives on the PlayStation 3, PC and Xbox 360 on Nov. 5, and also on the PlayStation 4 and Xbox One when those consoles launch. You can get Free Fall through GameStop, Target, Walmart, Toys 'r Us, Best Buy and Amazon. If you already pre-ordered, you're all good. If you haven't, will this new map get you to reserve a copy?
