SystemFiles' Counter-Strike: Global Offensive cheat really is the all-in-one package. The cheat is very customizable, even lets you decide what you want the colour of the ESP to be. It has a warning system, like most cheats here, which is very smart and helps you on the verge of impending doom (death). The crosshair is, too, very flexible - you can choose between a dot, a cross or a T-Cross. I personally favour the T-Cross and I find it exceedingly useful minimum size.
I have had no problems with this, it is great! (If you do decide to check out this cheat, look at my config in the GO customer forums! )
In conclusion, the CSGO cheat is very user friendly while being advanced. So if you need an edge over your opponents, this is the cheat to get..
