What you doing on 13 November? If the answer isn't playing Call of Duty Black Ops II then you probably won't be interested in the following."What happens when the enemy steals the keys?" That's the question asked in the new trailer that has been released ahead of what is expected to be yet another hit in the Call of Duty franchise.This time around it looks to all have a "Terminator"-style approach to the proceedings with drones - plenty of them - taking over where you left to fight back to save the world.Judging by the two-minute trailer there will be plenty of aerial fighting, plenty of tight city action in places like Los Angeles and even some horse trail action in the desert.The trailer also suggests there will be plenty of time to fly, crash, drive, and ride your way through the numerous levels that Treyarch, the game's developers, has in store for us come November.Are you excited by the trailer?
