Peaple call him cheater without thinking that “he is not playing against opponents with his same skill lvl” so given he won a tournament, him playing at home is like a professional soccer player against amateurs
If you watch carefully 0:15, you should notice that building landed 2 people. So 2:30 is not wallhack, it is information you got when you parachuting. For those who are saying that he looked right to see his second screen which is wallhacking screen, you should know that some professional FPS gamers have their screens really close to their eyes which can make them see pixels in games which can make you shoot more accurate and notice people moving even when they are hiding in bushes. So in face cam, their heads and/or eyes will have larger actions than normal screen distance people. (If you play league you can check FPX Nuguri face cam, everytime he looks at the minimap he turns his head to see it.)
because his eyes look to the right every time he looks to the right, there seems to be a second screen and the second screen is a wallhack, I think so.
