I'm giving this a 5 purely for the Zombies, nothing else in this game is worth playing really. (Also you probably can't even play the multiplayer anymore since there's no players in anything but Team Deathmatch) This is by far the best iteration of Zombies and the one I consistently keep coming back to almost 10 years later. The best story, a combination of all the best maps, all in addition to a lot of player-friendly changes from previous iterations of Zombies.
