Zombies will attack the shelters of alliance members in waves, and cease attacks after a member’s shelter is breached twice.

After the first breach your shelter will be on fire. At that moment you will start reinforcing ally shelters which are not on fire.

After each wave please check your hospital for injured soldiers and heal them.

How long you will be able to stand against waves of zombie attacks is related to your City Gate’s level. For better results please update your city gate whenever you can.

Don’t forget to garrison your strongest troop at the city gate. Please check it before the event starts.

Grab some snacks and drinks and enjoy this chill event. Then enjoy the rewards :)
