Two-player video game

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, putting the player against preprogrammed challenges or AI-controlled opponents (which lack the flexibility of human thought). Multiplayer games allow players interaction with other individuals in partnership, competition or rivalry, providing them with social communication absent from single-player games. In multiplayer games, players may compete against two (or more) human contestants, work cooperatively with a human partner to achieve a common goal, supervise other players' activity, co-op, and objective-based modes assaulting (or defending) a control point. Multiplayer games typically require players to share the resources of a single game system or use networking technology to play together over a greater distance.

Some of the earliest video games were two-player games, including early sports games (such as 1958's Tennis For Two and 1972's Pong), early shooter games such as Spacewar! (1962) and early racing video games such as Astro Race (1973). The first examples of multiplayer real-time games were developed on the PLATO system about 1973. Multi-user games developed on this system included 1973's Empire and 1974's Spasim; the latter was an early first-person shooter. Other early video games included turn-based multiplayer modes, popular in tabletop arcade machines. In such games, play is alternated at some point (often after the loss of a life). All players' scores are often displayed onscreen so players can see their relative standing.
