I speced you for once for people suggestion. But I didn't found nothing special, only sound and skills. Most of people who complains me about someone hacking. Well most steam players have good headset and believe me guys there are watching radar to know how enemie playes. I can give you example, I can hear you in mid example if you are fighting front of tunnel. But my main problem is I dont have net

But let see Kelly's demo, sure people can make mistakes or you really did hack this time

Well if you have watched some videos and played cs with steam servers, you will know places or spots people usually camps.
Ps. I don't mean that steam players cant hack xD
