Single player is fun. They do a good job in singlezplayer multiplier (1 person playing multiplayer). I give this 2 stars, however, because their split screen isn't playable. It flat out doesn't work in zombies, and it is barely playable for multiplayer. The games for split screen either don't work or crash within a minute. The split screen view is also tiny, and frankly unplayable even if you get into a game that doesn't crash. This is seems to be a treyarch problem since infinity ward did an amazing job with their split screen in all their titles Including the newest modern warfare. The split screen is unacceptable in this game for it being basically perfected in the latest release before.
