Call of Duty: Advanced Warfare's first expansion pack, Havoc, is set to release on January 27, 2015, developer Sledgehammer Games announced. Of course, PlayStation owners will likely have to wait a bit longer as Call of Duty DLC tends to release first on Xbox LIVE, but no biggie.

While Sledgehammer promises more details "soon," only teasing the four new multiplayer maps, a full rundown of the DLC was provided thanks to a GameStop listing. The listing details the four new maps — Core, Urban, Sideshow, and Drift — and gives a brief backstory of the new Exo Zombies mode.

Multiplayer Maps: Core: Deploy to the Gobi desert where the ravaged ruins of a nuclear fusion plant set the stage for a high-octane warzone. Take down enemies through the wreckage in long-range combat or get up-close and personal in the tunnels surrounding the central turbine. Activate decontamination drones using the map-based scorestreak to help clean out the competition. Urban: Prepare yourself for brutal, high-speed combat in Dallas Ward 3, a future mega structure, funneling players into a close-quarters free-for-all. This modular compound's verticality unleashes the exoskeleton's capabilities. Stay focused during the timed event as blast doors alter the map's flow and sightlines. Sideshow: In the shadow of Devil's Tower, Wyoming, this abandoned motel's open layout amplifies its creep factor. Blast your way through the clown inn with close-quarters battles or use long-range site-lines from the mining facilities and natural terrain. Use the map-based scorestreak to activate the lights, music, and magic of the clown marquee and rain down a barrage of rainbow smoke-trailed cannonballs. Drift: An idyllic ski resort high in the Rocky Mountains is transformed into a festive high-altitude playground, perfect for an all-out firefight. Make your way to the highly contested overwatch position in the glass observation deck or take a ride on the carousel to deliver 360 degrees of carnage. Players can use the map-altering timed event to their advantage as an avalanche of snow and debris disorients players, intensifying the battle. Exo Zombies Get ready for a new breed of Zombies. A DNA bioweapon unexpectedly spawns a bloodthirsty, ravenous mutant horde infecting an entire secret Atlas research facility and sending personnel running for their lives. Following a failed evacuation, four survivors, un-trained and underprepared, must face the most vicious mutations ever unleashed. The unique Exo Zombies co-op experience is all-new to Call of Duty: Advanced Warfare DLC. This new mode brings the movements, abilities, and weapons of the exoskeleton into battle against the undead.
