Modern Warfare III, the 2023 entry in the long-running Call of Duty series, uses distinct hitmarker audio to confirm damage, with headshots getting a sharper, more rewarding cue. As gameplay clips and montages spread on YouTube and TikTok, editors began lifting that cue to punctuate their own kills, even in videos from other shooters. It remains popular because it is instantly readable to anyone who plays first-person shooters, signalling a clean kill in less than two seconds without any explanation.
