The game's campaign follows Modern Warfare 2 and begins right after the events of its final mission. Similar to Modern Warfare 2, it is centered around the Task Force 141, which contains Captain Price, Soap MacTavish, and Yuri, one of the playable characters. Alongside the Delta Force and Special Air Service, they hunt Vladimir Makarov (antagonist of Modern Warfare 2), a Russian terrorist who leads the Russian Ultranationalist party. He leads several terror attacks across Europe, triggering a large-scale war between the Ultranationalists and friendly forces. For the game's multiplayer mode, new mode types and killstreak choices were brought in.
