Modern Warfare 2 is basically an upgraded and improved version of Call of Duty 4 Modern Warfare. The characters are amazing and likable, the graphics look stunning for a 2009 game, locations were awesome and so were the missions. The music was incredible, and the story added more depth to the Modern Warfare world and added a much bigger stake to the main character's mission. The ending is also iconic and memberable and will continue to be memorable, I think, for a long, long time. I can't wait to play through Black Ops 1 and Modern Warfare 3. 👍
