I found some issues. Not very important but good to know. People who said that 1 shot kill doesn't work, or the aimbot doesn't work.. they have partially right. Some guns don't work well with the aimbot. I haven't checked it with every gun in the game but let me share you my experience.
I tried shooting with the 3 shotguns of the game, and the aimbot was not working right. Actually I got a kill sometimes at 1st bullet and sometimes after shooting 4-5 bullets. Not always a headshot kill but that is a good thing anyway. Also when the aimbot shoots at a target, and didn't got the kill(middle of shooting), it starts shooting on another target. you don't get a kill and of course you die...
