In video games, a raid is a type of mission in Massively multiplayer online role-playing games (MMORPGs) where a much larger number than usual of people specifically gather in an attempt to defeat either: (a) another number of people at player-vs-player (PVP), (b) a series of computer-controlled enemies (non-player characters; NPCs) in a player-vs-environment (PVE) battlefield, or (c) a very powerful boss (superboss).
[3] The combat encounters comprising a raid usually require players to coordinate with one another while performing specific roles as members of a team.
Raids are often very rewarding in terms of virtual treasure and items that are unique or that grant exceptional stats and abilities, thus giving players an incentive to participate.
[6] An attempted raid in the game Final Fantasy XI against the Pandemonium Warden lasted 18 hours and reportedly resulted in players "passing out and getting physically ill." .
[7] Game raids are commonly organized by internet celebrities with the intent to protest against the company's behavior, their actions or simply for fun.
