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, pitting 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 or e), 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.
