A social media user identified as CyberLeek posted a video in which a character named Jason Duval shoots at a wall, causing bullet marks that spell "LEEK." The clip also shows a blue-and-yellow prop plane flying over a city resembling Vice City, and the game pauses to switch between radio stations such as V‑Rock playing Stevie Nicks' "For What It's Worth" and Back Country Radio playing Glen Campbell's "Rhinestone Cowboy," as well as Symphony FM. CyberLeek said the footage demonstrates access to a playable build and announced plans to release the ending for the character Lucia Caminos later that day, accompanied by an online poll. Earlier leaks included footage of Jason playing basketball and using a taser-like weapon to shoot people. CyberLeek stated the leak is an act of defiance after Rockstar announced the game would not be released on physical disc, and the user also includes advertisements for memecoins within the videos.

The official "Extended Look" trailer for GTA VI is scheduled for release on August 27, first appearing on Netflix at 3 PM Eastern Time and then on Rockstar's YouTube channel at 9 PM Eastern Time. The game is set to launch on November 19 for PlayStation 5 and Xbox Series X|S.
