I never said it was more than my opinion.That's simply your opinion we have yet to see the zombies in the future dlc. But if your talking about the single wave of zombies which is merely a teaser, then yes it doesnt live up to the old zombies because there is more of it.
Well the Zombie part is suppose to be a big part. So not saying any of what I'm saying now is confirmed but I could possibly see a little story along with it.Its not because the game is not a zombies based game. They cant make a campaign because its not based on it its just a fun side mission and dlc
