Summary
A 13TB torrent of Steam depot data from 2003 to 2013 surfaced publicly in the past 24 hours, with investigators already confirming beta builds for thousands of games including Portal 2, Left 4 Dead 2, Dragon Age: Origins and Batman: Arkham Asylum.
A publicly accessible Steam server endpoint appears to be the source, according to people tracking the archive, though exactly who pulled the data remains unconfirmed.
GitHub catalogs are indexing the leak as users sift through prerelease files and videos begin circulating; former Valve developer Elan Ruskin dismissed interest in early Portal 2 and Left 4 Dead 2 builds, saying the shipped versions contained the good ideas.
The archive stops in 2013, aligning with Valve's shift away from its older Steam2 storage system and making the leak a rare snapshot of a decade of pre-SteamPipe game development.
