A new trailer came out today for the last bit of DLC coming to Call of Duty: Advanced Warfare. It's called "Reckoning" and will bring new multiplayer maps to the game.
Reckoning includes the culmination of the Exo Zombies saga with Descent, as our heroes unravel the true cause of the global pandemic and the terrible secret that Atlas has been hiding. Also included are four exo grapple-enabled Multiplayer maps: Fracture, Overload, Quarantine, and Swarm. Take down your enemies in this globe-spanning collection that's filled with all-new map interactions and scorestreaks.

Obviously, the DLC releases on August 4 for the Xbox platform. Other platforms will probably get this content a month after in September.
