I love all of the references.. Haha, telling the plot of Guilty Crown start to finish as a threat? Good luck. :p I also love how the minigames become more intense than the last few, but I think that the ending was too empty, like the series was short.. maybe you could continue this on with a spinoff? Other than that I think it was a good series and this part was a good finish, considering all cliches of zombies.
