Raid (video games)
In massively multiplayer online role-playing games (MMORPGs), a raid is a type of activity in which groups of players team up to defeat a powerful superboss in an arena setting, waves of computer-controlled enemies in Player-versus-Environment (PvE) battles, or rival players in Player-versus-Player combat (PvP). Raids typically take place in instance dungeons—separate server instances isolated from the main game world.
Raiding is one of the most complex activities in MMORPGs, requiring careful planning and coordination among large groups of players, typically eight or more. While some games use matchmaking to assemble raid teams, others—especially older MMORPGs—rely on raiding guilds or informal methods like word of mouth and pickup groups (PUGs).
