Keep in mind few things:
1- You cannot use Aimbot and flick mode at the same time.
2- The menu is shown while you press the button ESCAPE and not while you are playing. (There is no open/close menu, the menu will enable when you press escape). Operate with the menu options by clicking on them or adding numerical values (10,100, 4.5, 200 etc)
3- If you want to assign a new “aim key” be sure to keep click at the hotkey button then HOLD the new assigned button so it registers properly.
4- If by any reason you are aiming at friendly targets press the BUTTON F12 TO AIM BACK TO ENEMIES!
