Call of Duty: Black Ops (mostly referred to as Black Ops, Blops, BO or COD 7) is the seventh main Call of Duty game, and the fifth developed by Treyarch. The game was published by Activision and for PC, Xbox 360, PlayStation 3, and the Wii. Officially announced on March 2nd, 2010, the game was released on November 9th, 2010. It could be considered as a sequel to Call of Duty: World at War due to it being the next war and because of Reznov's return.
Call of Duty: Black Ops differs from most previous installments, which would involve a usual three-country campaign while Black Ops features two playable countries (Russia and the USA), but only has an American campaign. Gamers play from the perspective of Captain Alex Mason of the MACV-SOG, Jason Hudson of the CIA, and Russian-born soldier Viktor Reznov of the Red Army. The game also introduced several new features such as dive-to-prone and the available use of a flashlight on certain weapons.
