The alert sting comes from Metal Gear, Konami's long-running stealth game series, where it signals that an enemy has spotted the player. Bass-boosted edits later became popular online as creators exaggerated the low end for comedy, turning a tense gameplay cue into a loud meme punchline. It sits alongside other bass-heavy reveal stingers such as the vine boom sound, and it remains popular because the original cue is instantly recognisable even when heavily distorted.
