- A thrifted Xbox 360 has been revealed to be an old Rockstar Games developer kit
- The console has a pre-release version of Grand Theft Auto 4 and 120GB hard drive full of unreleased assets
- Some assets included clipped content, including an apparent zombie mode
Fans have uncovered a collection of hidden Grand Theft Auto 4 assets on a used Xbox 360 that turned out to be a Rockstar Games development kit.
User ‘janmatant’ shared their find on fan site GTA Forum, revealing that they bought the console from a boot sale in Edinburgh, Scotland, for £5 (about $7), the same city where developer Rockstar North is located.
Pictures posted on the forum show the skimpy white Xbox 360 with a sticker on top that reads “Rockstar North Ltd” and has the Rockstar Games logo, but it’s the contents of the 120GB hard drive that have GTA fans go wild.

“HOLY. s**t. Something big has dropped,” said one user after the janmatant’s post.
After some research, it was discovered that the hardware appears to contain a 2007 pre-release version of the GTA 4along with a treasure trove of unfinished and unreleased assets that have now been uploaded to the Internet Archive.
In addition to ferry assets that appear to have been cut from the main game but were used in cutscenes and trailers, fans have also uncovered various radio stations and songs that differ from the release version, as well as unused weapons such as a revolver, a silenced pistol, unfinished animations, and beta versions of character models.
But the biggest discovery is what appears to be an unfinished zombie mode, which featured specific pickups and assets like bloody police bodies and a hospital stretcher.
As Kotaku reports, Obbe Vermeij, a former Rockstar Games developer who worked on GTA 4, has since said he doesn’t remember much about a zombie mode in a post on X/Twitter, suggesting it was an “experiment” by a team of artists and other developers “that didn’t work.
“There were a lot of them,” Vermeij added.
It’ll take fans a while to fully disassemble the 120GB of content, but at least they’ll have something to keep them busy while we wait Grand Theft Auto 6which launches on November 19, 2026 for PS5, Xbox Series X and Xbox Series S.
