The best first person shooter of 2007 without a doubt!!!
Gameplay: Even though the game is set in modern day the gameplay has not changed at all. As long as you aim through the scope, take advantage of the auto-aim, and you know how to preserve your ammo you will be fine.
Graphics: I am quoting this from the back of the box when I say that this game is "the most photo realistic game I have ever seen." The lighting, the particle effects, and everything else is absolutely excellent.
Sound: The music is the fantastic Call of Duty music that I have grown to love. The gunfire and the voice acting is also very good and realistic.
Story: In the story you play as many different army men as you run around and blast bad guys. The game is set in the Middle East and Russia. Sometimes you go back into the past, and not everyone makes it out alive. The story could be better, but it is good.
Online: This is definitely one of the best online games to date because of how deep and immersive it is. You are able to customize your character so that he has different perks, guns, and much more. You can unlock more things as you get better in the game. It is a lot of fun to be able to create a character that is right for you.
Overall: I highly reccomend this game and if you don't own this game you have to go and buy it right now!!!
