Why can't a single call of duty after world at war, allow split screen zombies with a guest account?! My mates come round and he's now having to set up a whole account just to play zombies.. stupid, also it seems like the game has been catered for next gen console owners as the multiplayer is so fast paced that you will need a console that has a higher refresh rate to actually get somewhere in the game, otherwise you're ending up with a 0.4 k/d
