I have tried probably every aimbot supposed to be a working crossfire aimbot but none worked. Plus i tried one color aimbot by legify which was made for combat arms but was said to be working with CF by someone but its just pain in the butt. You Make your CF gameplay in windowed mode somehow, do all the settings of aimbot but it doesnt do nothing except for selecting icons on my desktop having same color as chosen for aimbot.
So the conclusion is that there is no working aimbot for crossfire as of now but i have heard that the MPGH is working for an aimbot for crossfire but i highly doubt that cuz in CF VIP hack u dont really need an aimbot cuz there is already one hit kill available. And they would not release something in public hack that would affect their CF VIP income.
So you should buy a VIP here if you want something that rocks.
