Great multiplayer....not as great campaign.
Multiplayer: The guns are new, innovative, and just plain fun. all the multiplayer modes from CoD: 4 are there anlong with a few new ones, but this time you have to unlock the different multiplayer game modes by getting to higher levels. There are some great maps and a few stupid ones. 9.5/10
Graphics: Much improved Graphics from CoD: 4 10/10
Sound: Amazing sound with voice actors such as Kiefer Sutherland and the explosion and gun noises sound great 10/10
Overall: a great game to play... IMO CoD: 4 players will like the game. It is good fun and the different difficulties encourage multiple replays. I recommend picking this one up if you are a FPS fan or new to console games.
