Call of Duty: Ghosts Onslaught DLC officially announced and detailed

As expected, Activision has officially unveiled Call of Duty: Ghosts' first downloadable content pack, Onslaught. The new DLC will add four new multiplayer maps (small to medium scale), the new "Maverick" dual-purpose Assault Rifle/Sniper Rifle, and the first installment of Extinction's four-part episodic narrative, Episode 1: Nightfall. Here are the details, courtesy of Activision.

• Fog: Small to medium sized map set alongside the banks of a murky lake. Every area within "Fog" is a chilling homage to classic horror films, from an eerie campsite, flickering TVs, torture chamber, and seemingly abandoned structures as players try to unlock the map's dark secret. If a player happens to find and complete a specific Field Order, they become the embodiment of evil and don the persona of one of cinema's most iconic horror characters, Michael Myers. Additionally, the entire soundscape changes to the eerily familiar Halloween Theme music so other players know to run for their lives.
• BayView: A close-quarters map set on a costal Californian boardwalk packed with seaside gift stores and an aquarium, offering players fast-paced run-and-gun matches. Players must also be wary of the deadly artillery strike enemies can call-in from a Naval Destroyer anchored just offshore.
• Containment: A war-torn Mexican village where the battle rages along both banks of the dried out riverbed. Surrounded by a myriad of abandoned bars, cafes, a church and a pool hall, Containment also features elevated rooftop vantage points for players who prefer longer-range engagements.
• Ignition: An aging Florida space launch facility, inspired by Modern Warfare's "Scrapyard." On the map are two separate rocket test engines sites that opposing forces can trigger, sending massive fireballs into the already intense firefights, and the failed launch of a massive rocket has a dramatic effect on the combat.

In addition to the maps, Episode 1: Nightfall will introduce a new narrative for Ghosts' Extinction mode. The story follows two new characters and features two alien species and an exclusive weapon. "Set in a remote facility hidden deep within the Alaskan wilderness, the shadowy Nightfall Program has been researching the origins of the newly revealed alien threat," the description reads. "A small recon team of elite soldiers must infiltrate the site to retrieve intel and exterminate the hordes of savage creatures, and along the way uncover a three-story tall terror unlike anything they've faced before."

And lastly, Onslaught will give players access to the Maverick, a dual-purpose Assault Rifle or Sniper Rifle that can be switched on-the-fly depending on your needs.

Activision also confirmed that Onslaught will be available on January 28 for Xbox 360 and Xbox One. No release date for the PlayStation or PC versions were revealed, but if it's like past Call of Duty games then expect a 30-day wait.
