Call of Duty 4: Modern Warfare is a first-person shooter video game developed by Infinity Ward and published by Activision. The fourth installment in the Call of Duty series, it was released in 2007 for the PlayStation 3, Xbox 360, and Microsoft Windows. The game breaks away from the World War II setting of previous entries in the series and is instead set in modern times. Developed for over two years, the game uses a proprietary game engine.

The story takes place in the year 2011, where a radical leader has executed the president of an unnamed country in the Middle East, and an ultranationalist movement ignites a civil war in Russia. The conflicts are seen from the perspectives of a U.S. Force Reconnaissance Marine and a British SAS commando, and are set in various locales, such as the United Kingdom, the Middle East, Azerbaijan, Russia, and Ukraine. The multiplayer portion of the game features various game modes, and contains a leveling system that allows the player to unlock additional weapons, weapon attachments, and camouflage schemes as they advance.

Critically acclaimed, the game received an aggregated score of 94% from both GameRankings and Metacritic. The gameplay and story received particular praise, while criticism targeted the failure of the game to substantially innovate the first-person shooter genre. The game won numerous awards from gaming websites, including IGN's Best Xbox 360 Game. It was the top-selling game worldwide for 2007, selling around seven million copies by January 2008 and almost sixteen million by November 2013.
