Don't buy it! It's a buggy piece of shit that has a plot with quality on par of that of some soft core pornography. No replay value either. If you want to play it, go rent the shit from RedBox, provided that damn lady isn't still there trying to get a movie. Save your money and wait for Modern Warfare 3 to come out on Tuesday.
The shit was horrible, I'd rather whip out an old NES and play Contra than this shit.
You've been warned.
