In essence, Modern Warfare 2 extends upon the philosophy that Call of Duty 4 seemed to exude. Instead of branching out and trying radical new things, it simply polishes well-established things a little harder, pushing out another massively entertaining title that gets online shooter mechanics right, and then some. The story will either wow you or completely underwhelm you, but there's no denying that it's at least presented with an impressive amount of flair. It's a shame that PC gamers won't get any of the typical perks for buying it on their beloved platform, but as annoying as those omissions are, they don't detract from the actual meat of the game. Modern Warfare 2 will leave you breathless, regardless of which system you play it on.
