saw a comment on this mentioning the zombie noises in it, there ARE actually zombie noises in the original, you can barely hear them throughout the actual battle, but you can hear one loud and clear after the battle when the announcer says "who won?" in the original battle.
I couldn't even hear the original video (besides the intro & outro). Also, I did find a beat that had the beeps in it, though it was a different tempo and there were no zombie noises.
