I cannot tell you how great this game is. If you have an Xbox 360, or PS3, go out and buy this game right now. I am telling you this because I already know that if you are into shooter games, you will definately love this game. Starting out on a cargo ship in the ocean, you will fall in love with the awesome story. Unfortunately, the story is short, and is beatable in a day. If you are done with the singleplayer, you can move onto the multiplayer, which was named multiplayer of the year award in 2007. The multiplayer has many weapon choices, and it also has challenges the you can do to earn experience points. The bad thing about the multiplayer is that it is sometimes laggy, but it is still a lot of fun. Now onto the graphics engine of the game. I think that this graphics engine used is awesome, and it produces a great HD gaming experience. If you have a HD television, then you should look into an Xbox, and especially Call of duty 4. This game is the fourth in its series, and it is the first one set in the present, not world war 2. This i believe is the only game other than battlefield set in the present that can entertain you.
