OK....tried this method and tried 3 separate hacks and ended up with this....
Don't use a hack that draws anything on the screen.
FYI, hacks that use these functions are detected: GetTagPosition, DrawEngineText, RegisterFont, CG_Trace
So things that draw to the screen, or use an aimbot, will not work.
Simple things like my ESP works no problem. Just make sure you downgrade and it wouldn't be detected.
Also...I managed to totally patch aCI or Rev28 yay. Name Faking/ Xuid Spoofing/ ESPs/ No-Spread/Aimbotting is back x)
Also, "Steam Connect Failed" is given when you use a hack that uses the above or you hacked your name/stats/etc. from as far as I could tell.
