Easily the best single player Call of Duty campaign, and quite possibly one of the best FPS games ever. It does not get 5 stars though, simply because it still struggles with the kill boxes that all CoD single player campaigns struggle with, where regardless of what you try, you get repeatedly surrounded and gunned down by enemies you never see coming.

That said, the story and the pacing, as well as the gun play, are all top notch. I don't care for multiplayer, so I haven't touched it, but the single player is well worth the time.
