GTA: Freeway Fury 3
Cops are on the lookout for a crazy guy that jumps from one vehicle to another. He is deemed very dangerous as he had attacked several people already. Cops are instructed to shoot him on site as he is very dangerous. He might kill the cops if they get closer to him. On the other hand, he is also a hero since he fights the aliens that are trying to enslave us. Anyway, should you see him, it is advisable not to get close to him as he would attack immediately. Call the cops once you see him to be safe as he would not let anyone get close to him.
