The Call of Duty: Modern Warfare season one refresh is adding a bunch of new features. "Cranked" mode forces players to rack up increasingly higher kill counts or suffer an explosive fate. The Allegiance faction also gets a new character named Nikto, alongside a purchasable operator bundle. The trailer also shows off the new Gunfight and 6vy mode map, Shipment, a remake of the original map from the first Modern Warfare, as well as the Vacant map. The Docks Gunfight map also gets a holiday makeover, complete with bright lights and holly. Also included in the season one refresh is a new Spec Ops mode experience, as well as new limited-time modes to spice things up. The COD: Modern Warfare season one refresh is out on December 18.
