Call of Duty: Black Ops, developed by Treyarch, is the next installment in the Call of Duty franchise. It is rumored to be a first-person shooter set during the Cold War period. The game will feature an extensive single player campaign and competitive multiplayer modes as part of its core gameplay experience. This will be the second time in the series that it has gone back to a period prior to World War II, with 2008's Call Of Duty: World At War being set during WW2. With Black Ops, players can expect new weapons and technology from this era along with classic elements from previous entries in the series such as zombies mode and online play for up to 16 people simultaneously.
