The cue comes from Mass Effect, the 2007 science-fiction role-playing game developed by BioWare, where it marked Commander Shepard gaining experience and unlocking new abilities. As playthroughs, clips and edits spread online, the sound became a recognisable shorthand for levelling up beyond the game itself. It sits alongside other game notification sounds as a quick audio cue for progress, and it remains popular because Mass Effect fans instantly associate its futuristic tone with achievement, exploration and the original trilogy.
