the kill at 6:12 is pretty suspicious...enemy was not seen on minimap and he allready starts spraying while enemy isn't even in his sight.
Same thing with the kill at 7:02...i guess his wallhack confused him and thats why he looked at the left side aof the building first.
In my opinion...clear use of wallhack.
Look at 6:06 on the minimap: there is visible the enemy who looked in my direction. I noticed this, so I did not even reload and, taking the pistols, I started IMMEDIATELY, without a delay, to shoot, because I realized that the enemy would start to push me (because he was close and looked in my direction when I ran away that I could see on the minimap)
At 6:58, you can see on the minimap that the enemy is behind this house and by his movement you can understand that he is running towards me. I thought that he was still pushing me and started shooting prefire. But he somehow changed direction. If I had an aimbot or wallhack, I would not give such a prefire, right?
