modern warfare 3

The game opens moments after the cliffhanger ending of Modern Warfare 2 with the U.S. struggling to stave off a surprise Russian attack.
The single-player campaign, which appears to wrap up most of the unanswered questions and character fates of the first two Modern Warfare titles, also introduces new characters who appear to be destined for future Modern Warfare games, especially two Delta Force operatives codenamed "Frost" and "Sandman". Multiplayer in the game returns with a chunky list of playable maps as well as two types of Spec Ops modes: "Survival" and "Mission".

Modern Warfare 3 Multiplayer Features Battles in Brooklyn, Clash in Mogadishu 

Packed with 15 levels set in locations around the world, from Manhattan to the catacombs of Paris, Modern Warfare 3's near-future campaign looks to be an experience that will top anything seen before in a Call of Duty.
