Chams d/c regardless. I don't know why. But I use these hacks and I only turn on crosshair and wallhack. Wallhack is just as good as chams.
And for question 2, for some colors, they change if someone is behind cover, and comes out.
So if you can't see them > Green
If you can see them > Blue
For question 3, I do not know. It has not happened to me yet. The only time it won't change colors when pressing 9 for me is when there are no more colors available so I have to press 6.
My question was how I turn wall hack on, if Press 9, its change crosshair color Oo
And how I make the "behind coloer and the forward color" to be activated?
because I see Like blue if he behind a wall and blue if he forward a wall i still see BLUE pretty comfusing.
