Now it is your turn to protect the tower from zombies and mutants. There are tons of them wandering around. You are protected by a strong fence, but still you need to kill the enemies. They can gather a big crowd and break through into your territory. Therefore, a sniper should be always alert on the tower, shooting off approaching monsters. To kill a zombie, you must hit its head. There is a small white dot for the scope. The further the distance, the more points you get for defeating the target.
