Your hero at Ninja Assassin is a murderer ninja and he will do his job with your help. It consists in the destruction of those who have currently become his enemies. In fact, the task is to clean the warehouses. A large-scale attack is expected on them to rob. Guards walk around the rooms with boxes, illuminating their way with lanterns. If the ninja is in the zone illuminated by the lantern, the guard will see him and attack him. You should be selected from the dark side and instantly attack. The whole process is silent so that other guards are not wary of Ninja Assassin.
