One of the more progressive features in this year's Call of Duty instalment is the introduction of a new Squads mode to the Call of Duty: Ghosts multiplayer component, offering a variety of new game types that revolve around players building and customising a full squad of AI controlled teammates.

The latest trailer offers a good overview of squads, describing how each member can be levelled up and outfitted for custom strategy, then used in several different cooperative and adversarial ways, with and against other players.

Call of Duty: Ghosts is due on November 5 2013, for PC, Xbox 360, PlayStation 3, and Wii U, with PlayStation 4 and Xbox One offerings also due at each console's launch.
