Tried your cheat with 3 days trial. Played almost 10 games without problem. I have founded here everything i needed to know.
But hint for newbies, DONT KILL EVERYONE at once ! and follow recommended settings for cheat

I always play like before, always shot somewhere else except enemy because it will be suspicious to always hit enemies from long range and also be killed from time to time!

And my main reason why i bought this? Not to be first on server, but its f... hard and i dont enjoy the game with first guns when rank 90 to 100 kill you with one shot

Thank you guys again and again.
