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. Video games are often single-player activities that put the player against pre-programmed challenges and/or AI-controlled opponents, which often lack the flexibility and ingenuity of regular human thinking.

Multiplayers components allow players to enjoy interaction with other individuals, be it in the form of partnership, competition or rivalry. Furthermore, it provides them with a form of social communication that is almost always missing in single-player oriented games. In a variety of different multiplayer game types, players may individually compete against two or more human contestants, work cooperatively with a human partner(s) in order to achieve a common goal, supervise activities of other players, or engage in a game type that incorporates any possible combination of the above. Examples of better-known multiplayer game types include deathmatch and team death match, MMORPG-associated forms of PVP and Team PvE, capture the flag, domination (competition over control of resources), co-op, and various objective-based modes, often expressed in terms of "assault/defend a control point". Multiplayer games typically require the players to share resources of a single game system or use networking technologies that allow players to play together over greater distances.
