The Zombies are attacking! We need help! Help us raise a barn to protect our pumpkins and ourselves from the evil Zombie Pumpkin eaters! Once a day you can pick if you want to fend off the horde or help build the barn, without the barn, we all lose all, as the horde will never stop. But we also can't all be building the barn or else the horde will stall our progress and eat all our pumpkins!
