The MoTD  isn't directly tied into the storyline directly, since it's in Limbo. Nuketown isn't storyline related either, as it's a bunch of CDC members/CIA agents who went to investigate the Nuketown bombing, and found zombies. Green Run and Die Rise are story related, as part of Maxis grand plan to polarize the Earth with the pylons, finishing off the zombies. Or Richtofens plan to stop Maxis forever. There could feasibly be two more pylons left, unless one of the new maps turns out to be another red herring, along the lines of Nuketown or MoTD.
