Call of Duty 4 for the Xbox 360 must be the best game I have played for the console. I really enjoy the capabilities to upgrade weapons as you are promoted in rank and how the online multiplayer mode works. You seem to be able to work well with a team on this game and can depend on your teammates on certain matches. The weapons are advanced and realistic to modern weapons. I really like that this one is "Modern Warefare" it gives the player an idea of how things are now in our military and what weapons are used. The single player mode is also enjoyable although I dont like it as much as the online mode because you are not able to interact with other real people and work as much as a team. Overall I would highly recommend this game to everyone.
