A 12TB leak of Steam content, known as the 'teraleak', has released a large collection of game builds, including cut content and early versions of popular titles. The leak is believed to have originated from a publicly accessible API endpoint on Valve's old Steam2 server architecture, which was used between 2003 and 2013. The leak includes content from Valve and third-party publishers, and has been made available via a BitTorrent tracker. The leak has sparked interest among gamers and archivists, who are digging through the content to discover new information about game development history.
