Player Versus Player

Player Versus Player, or PvP, is a type of multiplayer interactive conflict within a game between two or more live participants. This is in contrast to games where players compete against computer-controlled opponents and/or players, which is referred to as Player Versus Environment (PvE). The terms are most often used in games where both activities exist, particularly MMORPGs, MUDs, and other role-playing video games. PvP is sometimes called player killing or PKing..
