Cheating in FPS by using a second computer to move mouse
I played competitive level Quake 3&#x2F;Quake Live for a number of years, during the height of its popularity. I also have friends who play more modern competitive FPS games, such as CS:GO. Even though QL was only a small online scene, the use aimbots, triggerbots, wallhacks, and similar tools was always very common at the competitive level. Quake Live had very limited anti-cheat functionality, so it was never relied upon for proving legitimacy. Despite this, cheaters generally didn&#x27;t last long in competitive play before being banned. Even if the <i>computer</i> can&#x27;t unequivocally identify the presence of these tools, skilled players could usually tell the difference. Even if skilled players couldn&#x27;t tell by watching alone, other contextual factors usually gave hackers away. Such as lack of LAN experience, no history of natural skill progression, etc. I&#x27;m aware that this doesn&#x27;t prove that we caught <i>every</i> hacker, just that we caught many of them.<p>These cheat tools could apparently be tuned to give extremely subtle advantages to players. Still, over a long enough time period the tool would eventually do something inexplicable enough by normal beahviour to give the player away. I haven&#x27;t exactly kept up with competitive FPS in years now, however it doesn&#x27;t seem hard to make aimbots that work well, it seems very difficult though to make ones that consistently appear <i>natural</i> to a trained eye.
