Valve archive leak hints at Episode Three, surfaces Portal 2 prototypes
A leaked 12TB archive of Valve development assets from 2003–2013 has surfaced online, reportedly including early Portal 2 builds, a Left 4 Dead beta, and material tied to the cancelled Half-Life 2: Episode Three. Researchers are parsing the files for clues about Episode 3 and other unreleased work; Valve has not commented. The leak is separate from Valve’s earlier CEVA Logistics breach.
