An amazing FPS and a great addition to the Call of Duty line up.
The US campaign is a heart stopping race through the streets of Iraq. And the British campaign keeps you on your toes when your playing as special forces. My only complaint (like many others) is the length of the single player, it is way too short. The campaigns leave you wanting much more, thats how good they are.
Once you are done with single player jump into the amazing multi-player. All of the familiar game modes are still there; S&D, Deathmatch, Team Deathmatch, etc. What makes the multiplayer really innovative is the class custimization. The more you play the more experience you get, this experience gets you ranks which unlock new weapons and bonuses. You then choose a primary weapon with upgrade, a sidearm with upgrade, and 3 perks. There are hundreds of different layouts that you can make, so you can fine tune your class to the way you personally play. All of the maps are great, and the developers have already added more maps.
This is an amazing game, even if you aren't going online. Pick this title up.
