I found this player flying all over the map trying to shoot us, his nickname is Keeway.
I was only able to record a small part of gameplay, but it clearly shows him flying:
User Keeway is blocked. Reason: Hacking / Using 3rd party software(s) to gain advantage in the game.
Thanks for reporting!
The battle was going to finish, that's why I am accepting it. Next time please follow the instructions provided here: How to report a Game Violator
Sadly he joined too late in the battle, and it took time to open my recording software, that's why the video it's so short.
Thanks for accepting it.
