Fantastic.
I got home from school, picked up my COD4 and have been playing it ever since. I have been playing mostly SP but I did take a break to MP. No real surprises, the game was as good as I expected to be. The shooting is extremely intense and the size of the battles in SP mode are really good. So If anyone was on the fence about this game, fear not, its excellent.
Game Developers! THIS IS HOW YOU MAKE A GAME INTENSE!!!!
