Modern Warfare is amazing. I don't care what platform your playing on, its fantastic.

The campaign is on the short side, still very fun a pretty decent story.

Spec-Ops is fucking cool, bunch of missions you can play solo or with a co-op split screen/online friend.

Multiplayer is godlike, it will be popular forever, as long as IW will keep updating and introducing new content.

Note: Throwing knives make you badass, just because they are 95% impossible to kill someone with, lmfao. It's cool though, I'm pro with them.
