The most disappointing part about Mob of the Dead is that it had absolutely nothing to do with the storyline. I am entranced in the story and constantly looking for more information. Mob of the Dead was like a brick wall in the story I was following. Not only did it not take place (according to the Easter Egg's headphone spawns) but it took forever for me to make sense of the events. To a guy who was constantly trying to put the story of zombies together, Mob of the Dead was very frustrating.

Also, I might be wrong that it had nothing to do with the story. Although unlikely, maybe Mob of the Dead will rub off on the main story in some later maps. Who knows?
