The game's campaign follows Task Force 141, a multinational special forces unit commanded by Captain Soap MacTavish as they hunt Vladimir Makarov, leader of the Russian Ultranationalist party, and United States Army Rangers from the 1st Ranger Battalion who are defending the Washington, D.C. area from a Russian invasion. The game's main playable characters are Sergeant Gary "Roach" Sanderson, of the 141, and Private James Ramirez, of the Army Rangers, with Captain MacTavish becoming playable later in the campaign. The multiplayer mode was expanded upon from the previous game, with several new features and modes.
