Game elements Landform Landmarks cannot be destroyed by bombs. You must avoid and attack overpasses and buildings. Types of zombies Normal zombies can be killed with one attack. However, you must be careful as some zombies cannot be killed with one attack. Additionally, strong zombies can cause greater damage to the supply base, so kill them quickly. Upgrade You can increase the number of bombs by killing zombies and collecting points. Supply bases provide unlimited bombs, but you cannot equip a plane with many bombs at once. Upgrading increases the number of bombs that can be equipped. Increase bombs to defeat more zombies. Repair When a supply base is attacked by zombies, it loses its durability. Without durability, you can no longer survive. Use your points to repair things to survive longer. Defeat endless waves of zombies and survive longer.
