A sequel to MW 2. In this 1st-person shooter the story picks up at the end of the previous game as Russia's invasion into the United States continues, but the war has now engulfed Europe, with Great Britain, France and Germany participating, allied to the US. You take control of various characters, like 'Soap' Mctavish from the previous game, and new ones, including Frost and Sandman, members of the US Delta Force.
The multiplayer portion comes with the usual modes. Also, it has new modes: Kill Confirmed mode and requires you to retrieve the dog tags of defeated enemies for the kill to register. The opposing team can also retrieve it to deny the player's kill. Another one, Team Defender, involves teams capturing a single flag on the map and keeping it for as long as possible to score the most points.
