Call of Duty 4: Modern Warfare on PS3 is the 2007 first-person shooter developed by Infinity Ward and published by Activision. It moved the series away from World War II and into a modern military setting, following U.S. Marines and British S.A.S. forces through a global conflict against a rogue enemy faction. The PS3 version includes the full cinematic single-player campaign and the competitive online multiplayer that helped define the game’s legacy. Multiplayer features class customization, perks, unlockable weapons, and a progression system that rewards continued play. The Game of the Year Edition later bundled in the Varied content from post-launch map packs, but the base PS3 release is the standard version.
