A multiplayer video game is a video game in which more than one person can play in the same game environment at the same time, either locally (e.g. New Super Mario Bros. Wii) or online over the internet (e.g. World of Warcraft, Call Of Duty). Multiplayer games usually require players to share the resources of a single game system or use networking technology to play together over a greater distance; players may compete against one or more human contestants, work cooperatively with a human partner to achieve a common goal, or supervise other players' activity. Multiplayer games allow players interaction with other individuals in partnership, competition or rivalry, providing them with social communication absent from single-player games.

Online cheating (in gaming) usually refers to modifying the game experience to give one player an advantage over others such as Aimbot in shooting games.[8][9][10] This is also known as "hacking" or "glitching" (Note that "glitching" refers to using a glitch, or a mistake in the code of a game, where as "hacking" is manipulating the code of a game). Cheating in video games is often done via a third party program which modifies the game's code at runtime to give one or more players an advantage. In other situations, it is frequently done by changing the games files to change the game's mechanics.[11]
