There have been many single-player stories in the Call of Duty Franchise. The story that stands out among them all is the campaigns from Black Ops 1 and 2. The story in these two games was awesome. The most creative storytelling in Call of Duty's history comes from Black Ops 1 and 2. Rather than make a generic war game centered around the Vietnam War and Cold War era, the developers decided to make a story that had deep plot featuring plot twists and many memorable moments. There are not many Call of Duty games that make you emotional and keep you on the edge of your seat. Black Ops 1 and 2 do both.
