I managed to have fun at times with hakk but unfortunately I didn't have a good experience like most here seem to have, the aimbot was always shaking and that caused me a kind of vertigo, besides the tracking didn't work for me, as soon as I pressed the o key character looked totally up and in relation to seeing the characters through the walls, the experience was not as fluid as expected, the lines between enemies and allies kept changing, being difficult to know the real distance of the enemies, despite the difficulty I managed to get good information of this.
Seeing through walls was a better experience than just using the aimbot, but the best thing to do is to use both together, it may be that my unsatisfactory experience stems from my hardware, because the reviews are very good on the forums, and some other time is worth a look. worth giving the tool another chance
