2. Modern Warfare 2 (2009)
Modern Warfare 2 has one of the best stories and definitely the best twist in the franchise, and for many, it could easily have taken the number one spot in this ranking. The invasion of America was inspired, and you really got a sense of making a desperate, last stand, while fighting through suburbia.
Of course, we also have to mention the infamous "No Russian", which remains probably the most controversial mission in franchise history. Looking back it's insane to think they included this, and it was probably a step too far, but it definitely helped set Makarov up as a great villain.
I only have one real criticism. The sniper mission, Contingency, was much weaker than its counterparts from the previous two games, All Ghillied Up and Vendetta.
