Call of Duty 4: Modern Warfare and its sequel Modern Warfare 2 are not only some of the best Call of Duty games ever, but also some of the best and most important games of all time. While Modern Warfare set the gold standard for what these first-person shooters could be, Modern Warfare pushed it to an even higher peak.

Character mission unlocks, two great maps (the second of which, Alcatraz, was reskinned as Rebirth Island), a fun armor system, interesting abilities, and a colorful map full of locations that celebrate Black Ops' history all come together to create a replayable battle royale mode oozing with personality.
