Active means the aimbot is active....*facepalm*

aim angle means you only lock on to someone in (default) 30 degrees of your crosshair.

Critical distance means that if someone is next to you, it autoswitches to try and kill them.

Smooth aim just makes the aimbot not lock on immediately. I reccomend around 6 if youre going "legit".

Hope that helped, and have fun cheating!
