Right hello there. I am a pretty hardcore player of GTA on the ps4. I use the free aim targeting mode and I would say I'm not to bad at it. But I joined a death match and this kid was farming headshots on like 2 bullets? SO I asked him how is that possible and all he told me was "DNS CODES". So going with that is there DNS codes, that I was unaware of or was he doing some other crap to kill players who were on full health. In 2 bullets and get accurate headshots every time?
