Man buys Xbox 360 for $6, discovers extremely rare Grand Theft Auto developer kit

A man in the United Kingdom purchased an old Xbox 360 for £5 ($6.64) from a car boot sale in Edinburgh, and within it was a Rockstar North development kit for Grand Theft Auto 4.

The development kit had a stunningly big prototype of the classic Grand Theft Auto 4, which debuted on the PlayStation 3 and Xbox 360 on April 29, 2008. The buyer took to the GTAForums to share a link to the extracted development kit, which revealed a ton of previously unseen assets, character models, missions, and other aspects of the game.

For those wondering what a development kit for GTA 4 actually is, it's essentially a pre-release version of the game that includes extra tools that give developers deeper access to the system.

Developer kits are provided to employees to test various aspects of a title, allowing developers to fine-tune the game and improve the final release. It's not uncommon for these developer kits to include assets and files that don't make it into the final release, which appears to be the case here.

The contents of the developer kit have been dumped and uploaded, with an extensive list of the files. Furthermore, the GTAForums user janmatant, who claims to have purchased the console from the trunk of someone's car, said they attempted to sell the developer kit on eBay, but the listing was taken down for "intellectual property" violations. Despite these violations, Janmatant is still looking to sell the developer kit.

In other Grand Theft Auto news, reports indicate that GTA 6 is going to have a next-gen breakable glass system for vehicles.
