A
raid is a type of mission in a
video game in which a number of people attempt to defeat another number of people at a PVP battlefield. The term
raid itself stems from the military definition of a sudden attack and/or seizure of some objective. This type of objective is most common in
MMORPGs, and usually but not necessarily occurs within an
Instance dungeon. In
RTS games like
StarCraft, the term is used differently; see
Raid (military).
