for deltaexcuteruser51 cOOlkidd
Is it visual or it works ?
@Slawke88 yes it works
it is visual u can scan in every game with out it kicking you and it works i will finde what ever it can finde try it
@cOOlkidd_v2 is it possible , to backdoor ,not visual ,like everyone needs to see that
since this only scans (while not kicking you) could you possibly either update, or make another ui for a executor. since most other backdoor scanners kick you from the game, and place you in a empty new server
ya it is
yeah it is possible with a right scripting skills
if and find the backdoor do you get serversided
