#9 Modern Warfare 3
Modern Warfare 3 may be the third in the series, but unlike so many other trilogies—it's actually as good as the first, surpassing the somewhat mediocre second game in every single way.
The campaign—from start to finish—is a well-crafted, and more-than-competent experience that's enough to give the best hollywood action movies a run for their money. Like the previous games, the player takes on the role of multiple characters as they travel across the globe to end the third world war, in concert, and defeat the terrorist who started it all.
