Grand Theft Auto IV was released by Rockstar Games in 2008 for consoles and PC, following Niko Bellic in Liberty City. Its mission complete cue became one of the series most recognisable audio signatures, separate from the louder stings used in other entries. As GTA clips and meme edits spread on YouTube and social media, creators lifted the sound to use outside gameplay as a universal mission passed moment. It remains popular because anyone who played the game instantly understands the meaning, even without seeing any GTA footage.
