The sound comes from R.E.P.O., a cooperative horror game in which players loot haunted locations while avoiding monsters, including the Robe, a cloaked monster that attacks players at range. As gameplay clips and horror edits circulated online, its distinctive attack cue was lifted for soundboards, where fans reuse it to recreate that sudden sense of being hunted without needing the full game footage. It remains popular because the cue is instantly recognisable to players and works as a compact warning signal in short videos.
