Modern Warfare almost didn't happen. The execs at Activision were gunshy about letting their popular WWII shooter break the confines of its now familiar theatre of operations. However, the creative blokes at Infinity Ward won the day, and Call of Duty 4: Modern Warfare became a reality. It also became a huge megahit, possibly qualifying as a phenomenon. The simple yet insanely visceral action won over just about every first-person aficionado, even the Halo faithful. Not to mention the online multiplayer portion of the game which rewrote how online multiplayer should be handled. Modern Warfare 2 (MW2) has much to live up to. Does it succeed?
