Hello

I have some doubts of the legitimacy of this player

In this gif it seems like he is locking to the first assault guy,and tries to fight against the lock in the end. Then,that support guy comes and he instantly locks to him. Take notice that his recoil is also nearly non-existant.

Here we have him aiming towards smoke,okay fair enough we can assume there might be someone. But the real case is that the recoil is also next to non-existant and it seems like there is that lock on.

Same situation as above,gyazo just didnt allowe to make a longer gif. But this time he just lock to the target far-away,and zero recoil. But when the enemy dies,he suddenly has some recoil.

And here we see him getting a lock on from hipfire while he switches to ADS. And while in ads,his aim lock above the line he was about to shoot. I mean,he could had just continued with the straight line leading the target,but instead the lock raises his aim in milliseconds.

All these gifs are made in 0.25 speed. Being able to lock on such a short amount of time is remarkable.

Edit: Added video channel to make conclusions,i picked some strange scenes straight from those videos. All those videos are short,except the last one.

Hello,this player seems to show some sort of artificial aiming in his video.

I collected some points into the gifs,you might expect the similar action to happen in through all that video. The gifs are slowed down to 0.25 speed making it a very remarkable feat to perform such lock on's.

I suspect him of using an aimbot. He also has some interesting anomalies,like performing of these two rounds might indicate:

Edit: Some more strange acting weapon behaviour from that video

So we are left with an impression he is just a very,very good player with perfect recoil control (alltho he makes sudden misbehaviour in certain parts) with many high-end players contributing comparable footage of how the game mechanic works,but he just doesnt have the same mechanics applied?

So he can do this https://gyazo.com/2ad4374c07c9b07a23b008023e5b9c08
and https://gyazo.com/ba34bb0663ed9a9976d90c266a1b34f9
but then struggles with https://gyazo.com/a773296af12274f2eddd5164e5161142 ?

What is fairly,it doesnt move at all and i just tested it with 120 fov and 70 fov,it has no difference the reticle still increases. He has it completely still. Even on .25 speed

Okay,so its totally normal that your hipfire reticle doesnt increase when you shoot?

Hello.
Med0vik updated this video today. In the parts of video,there is very,very suspicious gun behaviour.
Most of the time looks like he has no recoil at all.
@0:29 he is jumping with his G18 without hipfire reticle increasing,he even stops with it and still no increase,rather it goes down when he starts to shoot.
@1:04 he jumps down to hipfire whole squad with aek,no hipfire reticle increasement at all,and finishes with g18,no increase in reticle. It goes on without any visible recoil.
Then,at the @2:46 he suddenly has recoil,out of nowhere,like he has never shoot with the gun before. @3:40 he shoots through smoke(okay,nothing suspicious here many people just spray through it) but the explosion has no effect on him(im not totally sure is this the real effect).
@3:53 he shoots the dorito like any player would,but his gun is perfectly still,no sway to any direction at all.
So i conclude this is VERY suspicious behaviour taken count his history.
