Quake, id Software's landmark 1996 first-person shooter, used short, functional audio cues to confirm in-game events, and the default kill beep is one of those understated signals. Rather than a dramatic sting, it simply confirmed a frag, which helped it become a familiar shorthand among players who grew up with arena shooters. On soundboards and in edited clips today, it survives because that brevity works so well online, instantly signalling a successful hit to viewers who recognise classic shooter feedback without needing any explanation.
