Place it at the end of a chase or fight sequence, after a Dun Dun Dun build-up and just before the reveal of the defeated player. Follow it with the Fortnite Death Sound to close the moment, then cut to the next round without adding another kill effect.
About this sound
This is the Butcher Circle killsound, a game sound effect that marks a kill. It lands with a sudden, tense impact that makes a defeat feel dramatic and final, giving a clip a sharp edge without needing any dialogue. It comes from FPE:S, where it plays when a kill is scored.
