Call of Duty: Ghosts will introduce a new type of hybrid AI-and-human multiplayer experience called Squads.
First, a player forms their own Squad, a group of soldiers with varying perks and load-outs designed to support a certain play style. This squad then levels up and progresses as the player unlocks XP throughout the various Squad-centric multiplayer modes. All of the XP earned in each of these Squad modes can then carry over to the multiplayer experience proper.
Call of Duty: Ghosts launches on Xbox 360, PS3, Wii U and PC on November 5. PS4 and Xbox One installments will be available during those respective console launches.
