On online games, cheating subverts the rules or mechanics of the games to gain an unfair advantage over other players, generally with the use of third-party software. What constitutes cheating is dependent on the game in question, its rules, and consensus opinion as to whether a particular activity is considered to be cheating.
Cheating is present in most multiplayer online games, but it is difficult to measure. Various methods of cheating in online games can take the form of software assistance, such as scripts and bots, and various forms of unsporting play taking advantage of exploits within the game. The Internet and darknets can provide players with the methodology necessary to cheat in online games, with software often available for purchase.
As methods of cheating have advanced, video game publishers have similarly increased methods of anti-cheating, but are still limited in their effectiveness. Punishments for cheaters also have various forms, with legal measures also being taken against those who create or use cheats. While some countries include laws that prohibit and punish cheating, video game companies have a history of citing copyright infringement in lawsuits against cheaters.
