As promised during the interval of the Champions League final, Activision released the second trailer for Call of Duty: Black Ops II , the last episode of the series of war developed by Treyarch. Although compared to the first official video, this doesn't show the big news, it is interesting to observe once again some of the powerful enemies that we will have to face in the game as the armored Claw, a kind of huge Mechs animal shaped and equipped with powerful mechanical legs.
