No let down for World War 2 gamer fans here.
The game starts you off in training. A good thing too, because I've watched people try the game without it and it's pethetic. Anyways, you are a Russian in a ruin snowy town. After a few missions (hint: the missions are few, but they are long. Don't worry though, they have intermissions between sections where you can save.) you will begin the British campaign. They have to most missions. Finally you play as the Americans. You must beat all the British and Russian campaign missions first, but it is worth it. The American campaign is fun and the most exciting part of the game.
If you don't have an Xbox 360, then I feel sorry for you. I'm sure that this game, if you don't like it, will not be the last game for the 360. Overall, Call of Duty 2 was a game that you just can't pass up. As for all you haters out there, don't take this the wrong way, but I don't care what you say. Don't listen to me and go play you "PS2" and your "Game Cube" and leave us Xbox junkies alone.
