One of the biggest GTA IV leaks in history has just dropped, and the community is already unearthing a treasure trove of cut content from what appears to be a pre-release build of Rockstar’s beloved 2008 open-world classic.
From a zombie minigame to working ferries and overhauled radio stations, the findings are giving fans a fascinating look at what GTA IV could have been.
Where Did the GTA IV Leak Come From?
The leak originates from a GTA Forums user named janmatant, who claims to have purchased an old Xbox 360 developer kit — complete with a Rockstar North sticker — for just £5 at a car boot sale in Edinburgh.
Given that Rockstar North is based in the Scottish capital, it’s not entirely surprising that the hardware found its way to a local sale.
The user dumped the contents of the dev kit’s hard drive to the Internet Archive under the title Great Stealing of Vehicles four XDK.
The archive comes in at around 118GB and is reportedly playable on a real Xbox 360 with the appropriate debug tools.
Based on internal data, the build appears to date from around November 2007 — several months before GTA IV’s April 2008 release.
GTA IV Had a Zombie Minigame in Development
Perhaps the most exciting discovery so far is evidence of a zombie minigame buried within the beta build.
GTA Forums users Lukakion and HeySlickThatsMe uncovered a collection of assets with file names referencing a “Zomb” naming convention, strongly suggesting Rockstar had zombie-related content in some stage of development.
Former Rockstar North technical director Obbe Vermeij, who has become a trusted voice for insider GTA history on social media, stated he had no direct knowledge of a zombie mode, but acknowledged that Rockstar artists were “always trying to put zombies in things,” adding it was “not something that got very far.”
Regardless, the existence of these assets confirms that zombie gameplay in a GTA title isn’t a completely new idea — it was being toyed with nearly two decades ago.
Working Ferries Were Cut Late in Development
Another major find is the presence of fully modelled Liberty Ferries — boats that fans may remember from GTA IV’s very first trailer but which were absent from the final game.
HeySlickThatsMe located the model and texture files in the beta build, reigniting debate about why they were removed.
Obbe Vermeij shed some light on this too, confirming that the ferries were cut late into development due to too many technical problems.
Issues included collision bugs and complications with NPCs and vehicles stacking on top of one another while aboard.
The ferries were intended to operate on a back-and-forth route, similar to the in-game train system.
GTA IV Beta Had Completely Different Radio Stations and Songs
Music lovers will find plenty to dig into here. GTA Forums user MGgames100 discovered more than two dozen songs across 11 radio stations that differ from the final game’s lineup, along with placeholder content and intro variations that didn’t make the cut.
For fans of GTA’s iconic radio culture, this is a significant find — the final soundtrack is widely considered one of the best in the series, so it raises interesting questions about what the game would have sounded like with an entirely different set of tracks.
Beta Cutscenes Feature Different Dialogue and Camera Angles
Beyond the music, the pre-release build reveals notable differences in cutscene dialogue throughout the game.
In one example, Niko and the ULP contact refer to the FBI rather than the FIB — the fictional in-game equivalent used in the released version.
Multiple voice-over takes also differ from what players heard in the final game, with extended scenes and alternative camera angles rounding out the changes.
Vehicles, NPCs, and Character Appearances Also Changed
On top of the headline discoveries, eagle-eyed community members are cataloguing a long list of smaller differences.
Several vehicles feature minor visual tweaks, NPCs appear with different clothing choices, and a handful of story characters have subtle differences in their appearance compared to their final designs.
The scope of this leak is enormous, and the GTA community is only just getting started.
As more fans dig through the 118GB archive, it’s likely that even more cut content will come to light.
We’ll be keeping a close eye on developments and updating this article as new findings emerge.
