Modern Warfare 2 is a vido game developed by Infinity Ward, and published by Activision for Microsoft Windows, Xbox 360, Playstation 3, Nintendo DS, and Blackberry. It is essentially about a war against the Russians. Throughout the game, you switch between many characters, so your perspective of each part of the war changes as you play. One moment you could be playing a character named "Soap" and the next you could be playing "Roach".

The Multiplayer on XBox LIVE, features Leaderboards, Challenges, and the ability to play with thousands of people around the world. With a different array of guns, equipment, and maps, the experience is overall, very enjoyable. Watch out for those campers though! They can give you a pretty hard time. The player-base on the game is very competitive, but you can find some very friendly people nonetheless.

You can go through ten prestiges, each of seventy levels each. As you go up higher in the levels, you unlock new challenges that give you XP, and essentially raise your rank within the leaderboards, whether it be aaginst your friends, or the world.
