We saw it happen with Modern Warfare 2 , we saw it with Black Ops, then again with Modern Warfare 3 and now all hopes are on this year’s Call of Duty installment, Black Ops 2. The sequel to 2010′s best-selling game , ‘Black Ops’ . Call of Duty wasn’t always the way it is now. There was a time when Call of Duty was trying hard to find an audience for themselves but they were lacking at something or the other. That was the time when Medal of Honor ruled the First-person shooters’ genre. Then came along , Call of Duty 4 : Modern Warfare. The game that changed the face of Call of Duty forever.
