Four years after the September 2022 breach that put roughly 90 development clips on the internet, the rest of that haul appears to have surfaced. According to Kotaku's Zack Zwiezen, reporting on September 18, someone with access to the full cache of roughly 190GB of leaked Rockstar material posted it publicly on September 17, and within hours fans on GTAForums, Reddit and X were pulling out two very different kinds of discovery: unfinished GTA 5 expansion content that had only ever been rumoured, and an early GTA 6 map build that the data suggests dates to around 2015.
This is a GTA 6 leak story with an unusual shape. Nothing in it is new footage of the game shipping on November 19. It is an archive of old material, and it says more about how Rockstar builds worlds than about what Vice City looks like today. Here is what has been reported, what it does and does not prove, and why we will not be pointing you at any of it.
Where the 190GB Came From
The short version, which we covered in depth in our 2022 leak retrospective: in September 2022 a teenage hacker breached Rockstar's internal systems and posted dozens of GTA 6 development videos. Before his arrest, the same person reportedly sold an older GTA 5 build and other stolen files to a buyer over Telegram. Those files circulated quietly among a handful of people for years, referenced occasionally but never dumped in full.
Kotaku reports that changed on September 17, when the complete set was posted openly. The material is being described as around 190GB, and a widely shared Reddit thread calls it a roughly 200GB GTA 5 source-code leak that also contains early GTA 6 content. Rockstar and Take-Two have not commented. The hacker's own legal story continues separately, covered in our Kurtaj retrial explainer.
What the GTA 5 Files Reportedly Show
Most of the early excitement is not about GTA 6 at all. Per Kotaku, citing a breakdown video from the modder TJGM and posts on GTAForums, the files include:
- Audio assets and code pointing to a Liberty City expansion for GTA 5 or GTA Online. Rumoured for a decade, ever since a screenshot from a Rockstar employee's portfolio appeared to show GTA 4's city running in GTA 5's engine. Kotaku calls the new files the best confirmation yet that the project existed.
- Mission names and assets from the cancelled "Agent Trevor" story DLC, which would reportedly have put Trevor to work for the government, with a space station, mansions and jetpacks.
- Files tied to Michael's cancelled expansion, long reported to involve zombies, with hints that players might have controlled his teenage children.
- Beta vehicles and unfinished assets, including what looks like a nearly complete combine harvester.
Every item on that list is leak-sourced and unverified. We have put the cancelled episodes in context, and explained what they mean for GTA 6's own post-launch prospects, in our cancelled story DLC explainer.
The 2015 GTA 6 Map
The part that concerns this site directly is an early build of what appears to be GTA 6's full map. Data inside the files reportedly dates it to around 2015, and the build seems to have been running inside GTA 5's engine, which is how a studio typically prototypes a new world before its own technology is ready.
Fans immediately started laying leaked locations over shots from the August Extended Look, and Kotaku's read of those comparisons is that the broad layout has not changed much in eleven years. What changed is everything on top: the visual quality, the density, the detail. Big open-world layouts get locked early; the years go into dressing them.
The comparisons also suggest something we have argued before in our map hub: a large portion of Leonida has still not been shown officially.
Why This Is Different From the Summer Leaks
The Cyberleek episode in August was a stream of short clips from a build variously dated 2023 to 2025, pushed by a leaker trying to sell a crypto token. Our standing rules for that coverage, laid out in our leak coverage ethics piece, apply here too: no embedding, no linking, no directions.
But this dump belongs to a different category of leak. In our history of the biggest game leaks we made the point that video of an unfinished game does essentially no commercial damage, while source code and internal data are the categories that cause real harm. A reported 190GB of GTA 5 era source material sits squarely in the second category, even if the game it belongs to shipped in 2013. That is why Take-Two's lawyers will treat this more seriously than a batch of gameplay clips, and why anyone tempted to download it should read our leak malware and scam safety guide first.
Spoiler Risk
The 2015 map is old enough that individual landmarks may have been cut, renamed or rebuilt. It is still a map. If you are protecting yourself from knowing what waits beyond Vice City, this is the moment to mute the usual keywords; our spoiler avoidance guide has the list. The Liberty City material is a GTA 5 question, not a GTA 6 one; our answer in Will GTA 6 Let You Visit Liberty City? has not changed.
Frequently Asked Questions
Is this a new hack of Rockstar?
No. Reporting describes it as the full cache from the 2022 breach finally being posted publicly, after years of circulating privately. There is no indication of a fresh intrusion.
Does the leaked map show the final GTA 6?
No. The build is reportedly from around 2015 and was running in GTA 5's engine. Early comparisons suggest the layout survived, but details, names and content from a prototype that old should be assumed to have changed.
Will this delay GTA 6?
There is no reason to think so. Leaks of finished or unfinished material have never moved a Rockstar release date, and Take-Two said the 2022 leak had no measurable financial impact. November 19 stands.
Is it safe to download the files?
No. Beyond the legal exposure, leak archives are a favourite delivery vehicle for malware, and the copies spreading now are unverifiable. Nothing in them is worth the risk.
The Bottom Line
The 2022 Rockstar breach has now produced its second act: a reported 190GB archive of GTA 5 source-era material and a GTA 6 map prototype from around 2015, dumped publicly on September 17. For GTA 5 fans it is a look at the story DLC that never shipped. For GTA 6, it is a reminder that the world was laid out more than a decade ago and that most of it is still unseen. It is also, for the second time in a month, a leak this site will describe but never link.
