Actually, both of you are technically wrong.... If you were to find the right address for 'aimbot'(not giving you guys an insight on how to find it); and you were to mod it correctly, bullet speed would not be affected(HINT*-bullet speed is not ServerSide!!!)..
and dragone is wrong in saying that it would not be detected... One of my trials has been accused of RoF Hacking when i used an aimbot

... , and you can find the 'lock-on' values in any Memory scanner/Debugger .. you just have to know the characteristics and how you would search for them..
