Player(s) versus player(s), 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..
