I don't know much about the zombies maps in this game. I would just like some people who know how to get the "story line" achievements to help me. I'm a good zombies player and all, I just don't know how to do it and would enjoy some help. (I have all but four zombies achievement for BO1, and they weren't the story line ones) so if you can help, please message me at my GT: KillerKeeton. Thanks in advance.
