Modern Warfare 2 takes players to the snow-capped peaks of Russian mountains, across the deserts of Afghanistan and into the streets of Rio de Janeiro, and introduces a new co-operative Special Forces mode to back up the single-player campaign.
This game has always done well for its single player spectes but with no multplayer improvements from the previous one(OR Any of them). It has the same graphics, same multiplayer, just more guns, killstreaks and campign.
