Speed Hacker here
Me and my random squad mate were one of the several teams left in the match, and guess what? I left he area which i checked less than 10 second ago and some guy with speed hack shot me from the back and rushed to me with his "super human" speed without breaking a sweat. He downed me and my team less than 30 seconds. Then i decided to watch him play the rest of the game cheating like a god, cough cough. His teammate might also be cheating, and might be from China as his name DouYu = 斗鱼 chinese streaming platform.
Teammate might be hacking too
