Call of Duty: Ghosts’ Onslaught DLC out on January 28th

The first DLC for Call of Duty: Ghosts now has a release date. Entitled "Onslaught," the DLC will include new maps as well as a new episode for the new Extinction mode. The DLC comes out on January 28th, presumably just for Xbox One right now which has timed exclusivity on all packs.
A promotional poster which leaked over the weekend named the new maps as Fog, Bayview, Containment, and Ignition. One interesting feature in the Fog map is the ability to play as Michael Myers once you complete a field order. The new Extinction map in the DLC continues the story of that mode explaining more about the alien invasion. The new trailer for the DLC is available below.
