Zombies conquer more and more territories, and people have to huddle in small fenced areas that can be protected. One of these places you will develop and protect in the game Zombie Day, helping the officer. He has a small area under his control, on which there are already settlers, but they need to be organized. Put one behind the machine gun to pour lead fire on the zombies trying to break through. Several assistants should bring ammunition regularly. Next, you need to resume the extraction of valuable crystals and their processing. Get weapons because you have to jump behind the fence to collect resources in Zombie Day.
