Anyway, in future, any region that I will be playing the Zombie Game in, they will all be password protected throughout the event. Zombies are way too powerful and cause way too much damage by comparison to how much effort is required to fix the damage. I can see in future over 2,500 of my regions being passworded days before and possibly take days after the fact to be reopened. All of the ones that are becoming zero zombie regions will for sure be closed.
Cannot do much about the day's featured region, as it was not passworded, or planned to be protected in any fashion. I understand why no one dropped by to say hello. I certainly would visit a region in this bad of shape. If I had have remembered to check last night which region was featured, I would have research military option and killed all of my residents, and by the time that any visitors came along, they would be safe from zombies, I think (I had not researched that concept).
