Hello every. Just an hour ago, I met this guy in GTA: Online who was fun to run down a couple of times. He got behind a pole where I was unable to mash him, so he took the advantage an tried to shoot me through the front window of my automobile, but surprisely I didn't lose any health, so I shot at him too, but everytime I had him in my sight and pressed the trigger, no beans would run out my AP pistol, even grenades affected him. I got out my car to make it more personal, but we just couldn't kill eachother with bullets and explosives. What is this?
