This clip comes from the sound library associated with Call of Duty Zombies, the long-running cooperative mode in which players survive rounds against the undead. Short extracts like this one have circulated on soundboards and in fan edits for years, because they are instantly recognisable to players even without any visuals. Creators reuse them to signal danger, parody horror-game tension or add a familiar gaming cue to an unrelated video. Its short length makes it easy to drop into edits, and that familiarity keeps it in regular use across gaming memes, streams and reaction content.
