In R.E.P.O., a co-operative horror game where players loot haunted locations while avoiding monsters, short notice sounds tell players an enemy spotted nearby before they see it. This duck notice cue is one of those quick warnings, clipped from gameplay and shared by players who recognised its tense, instantly recognisable sting. Creators now reuse it outside the game as a compact alert for danger reveals, jump scares and surprise moments in short videos, where its half-second length keeps the reaction sharp without slowing the edit.
