I've gone through all the campaigns and they are all pretty self-contained. You don't have to worry🏧 about previous storylines to get through this one. You don't need to play the earlier ones.

Black Ops II is the ninth game in the Call of Duty franchise of video games, a🏧 sequel to the 2010 game Call of Duty: Black Ops and the first Call of Duty game for the Wii🏧 U.
