Put it on the exact hit in a gameplay edit, then follow it with Monster Kill when that hit starts a streak, and keep Call of Duty Hitmarker nearby for the decisive shot in the same sequence.
About this sound
This is a 104-millisecond hit marker clip built around a rapid pew pew effect, with no voice and no music, just the brief electronic blip used to signal a successful hit. It feels sharp, instant and satisfying, like a tiny reward that lands exactly when something connects, giving a quick burst of excitement without lingering or getting in the way.
