This will be a short review, not much to tell :)

I've completed the campain multiple times, collected all of the intels, and thus, completed the game.

The single played game was to short, for players the either don't enjoy online or don't have the connection for it, don't get this game. 'nuff said

This game was oviously made to be online. The online portion of this game is outstanding. I would HIGHLY recomment thid game for online. You should play this game before playing COD4.5 in my oppinion.
