The sound comes from Konami's Metal Gear series, a long-running stealth franchise centred on the soldier Snake, where a short chime confirms that an item has been collected during a mission. Players first heard variations of it in the early Metal Gear Solid games, and it became familiar through repeated play, walkthroughs, and speedruns shared online. As clips of the series circulated on video platforms, editors began lifting the chime for their own loot, reward, and discovery moments. It remains popular because it is instantly understood by gamers, even without any visuals, as the sound of finding something useful.
