Call of Duty: Black Ops II was released in 2012 by Treyarch and its Zombies mode became one of the most played parts of the game, built around waves of undead enemies in enclosed maps. Short enemy vocalisations like this growl were ripped from gameplay and shared on soundboards and in video edits. The clip stayed popular because it is instantly recognisable to shooter fans yet works outside the game as a generic zombie scream, fitting horror memes, fan trailers, and Halloween content years after release.
