Nobody uses aim bot anymore. When I say aim bot I mean true aim bot where it snaps target. This hack has been faded out almost completely with the only ppl using it, want you to see that they are using it because it gets them off (trolls etc). The reason this true aim bot hack is barely used is because of the ability to detect it clearly by watching.
This hack has been replaced by "soft" aim bot, which is pretty much undetectable. Although there are ppl out there that are as good as the soft aim hack works - which is safer and allows user to not worry about being banned. Nobody is going to be banned for having amazing aim, especially when no illegal hardware is being detected. Dev's don't guess when banning someone.
So when your are insta-killed by a pred or master - makes sense, their aim is more than likely just that good. However, if a level 50 etc insta-kills you without missing a shot from distance, than you are either dealing with a smurf account or well - you figure it out.
Their is an industry now for selling hacks almost as big as the gaming industry itself. Check some of the sites and factual information on the number of times specific companies have sold out of these types of hacks/hardware and the time frame in which it has happen. Mind blowing.
But heh, I'm sure the majority of ppl today in this day in age would rather be amazing in the competitive FPS multiplayer gaming industry on the legit end than the one that makes them feel bad about themselves.....oh wait!
