Fallout: New Vegas is a role playing game developed by Obsidian Entertainment and released in 2010, set in a post apocalyptic Mojave Desert years after a nuclear war. Like other Fallout games, it rewards exploration and combat with experience points, and reaching a new level triggers this distinctive musical cue before players assign skill points and select a perk. Clips of the cue later spread across YouTube, TikTok and soundboards detached from gameplay, becoming shorthand for levelling up in real life, from gym progress to new jobs and exam results.
