Place it at the peak of a highlight, after the setup and just before the payoff shot. Open with Enemy Spotted to set the scene, then let this clip hit, and follow it with Bomb Has Been Planted to close the sequence.
About this sound
This is a short, roughly four-second clip of the Black Ops 2 announcer voice pushed into an over-the-top, high-energy outburst. It feels chaotic and funny, like a calm match call suddenly tipping into shouting, and it lands best as a surprise. It comes from Call of Duty: Black Ops II, where the announcer normally calls out match events.
