Hidden GTA 4 Zombies Mode Discovered in Dev Kit at Flea Market

An Xbox 360 development kit containing a beta version of Grand Theft Auto IV has recently surfaced and was snagged for just a few bucks. The kit’s contents have been uploaded online, showcasing a treasure trove of cut and unfinished material, including new weapons, beta cutscenes, unused vehicles, and even a glimpse at what appears to be a zombies mode that was in the works.

Over the weekend, a user on GTA Forums named janmatant stumbled upon this dev kit at a boot sale in Edinburgh, Scotland, the same city where Rockstar North operates, and reportedly purchased it for five pounds. The kit features a sticker indicating its use at Rockstar North and contains over 120GB of data, including what looks like a 2007 beta build of GTA IV, along with numerous unfinished or removed assets from the game. The entire kit has now been uploaded to the Internet Archive.

There’s a wealth of content to explore in this leaked build of GTA IV, and it will take some time for the community to sift through all the data packed into this dev kit. One of the most thrilling discoveries is the evidence of an unfinished zombies mode, which would have included specific pickups. Users digging into the build have also uncovered mangled police bodies and a bloody hospital gurney linked to this mode.

Some players have already begun to get beta assets functioning on PC, with mods for cut weapons like an early version of the AK-47 and a silenced pistol making their way into GTA IV. There’s also been significant progress in getting the beta cutscenes operational.

For fans of GTA IV or those curious about how a major title evolved before its release, this dev kit find is incredibly exciting. The enthusiasm in the GTA Forums’ thread dedicated to GTA IV beta content is palpable. This thread, which has been active for over a decade, had seen a decline in activity as most of the known content was documented. Now, with over 100GB of new early GTA IV material to explore, the community is buzzing with renewed excitement.
