Call of Duty: Modern Warfare 3's fourth and final collection pack features five new multiplayer maps, and this trailer gives a scope's eye view of all the death.

Here's how Activision describes the Final Assault DLC:

The final act of the Call of Duty: MW3 Content Season, Collection #4: Final Assault, is tailored toward hardcore multiplayer fans, and features five all-new multiplayer maps. “Gulch” sends combatants into a forgotten mining town with mine shafts and equipment sheds for cover. In “Boardwalk,” fun in the sun on the Jersey Shore means facing enemies on the beach. “Offshore” and “Decommission” will test players’ sea legs on deadly oceanic oilrigs and among a maze of rotting ocean liners, respectively. Rounding out the collection is a trip to the French Quarter in a war-torn New Orleans, where “Parish” pits players against one another amidst the city’s rubble.

The Final Assault collection is available first on Xbox 360 on September 6 (1200 MP), and a month later for PS3.
