Call of Duty: Black Ops Complete Pack Steam CD Key (Mac OS X)

Call of Duty: Black Ops is the seventh main Call of Duty game and the sequel to Call of Duty: World at War. The game differs from most previous installments, which would involve a usual three-country campaign, while Call of Duty: Black Ops features two playable countries (Russia and the USA) but only has an American campaign. Several new features are also introduced, such as dive-to-prone and the available use of a flashlight on certain weapons. Furthermore, the campaign's playable characters now speak while being controlled by the player.
