Wilk (I forget the rest of his name)
Walling and possible aim bot toggle

39 seconds - automatically aims at the enemy in window

1:53 - automatically aims at enemy on roof

2:27 - pay attention how enemy in cubby makes no sound, but Wilk not only prefires, but directly shoots at enemy before turning the corner

if you pay attention to chat, a myriad of ppl also notice his hacking and begin the votebanning process.
