You walk up to the resistance base and knock on the door. A man opens it. he looks a lot like the guy you had seen from the original terminator movie. You try to tell him to help you but at that point you hear the dogs start barking. It's then that the man points his gun at you and you black out.
coming back to your senses, you look around you, the base that you had tried to seek shelter in had been destroyed. On top of that your arm was injured. You couldn't feel any pain but something told you that one of it's motor units had become jammed in the fray. Wait motor unit?
All of a sudden the realization hit you. You weren't a human running from the terminators you were a terminator programmed to exterminate the resistance.
