Wow. Where to start. Ok 1) Black Ops is not the standard for zombies. There are many iterations of zombies, but the most classic example is the Romero zombie, which can only be killed via a headshot. Many other zombie narratives and games do this. 2) It isn't cannon, it's meant to give you a fun scenario with Marston, and is considered one of the best DLC's around. 3)For $10, this is a hell of a deal, one that can't be passed up. I got it the day it came out, and I still love it. Try not to be so nitpicky.
