A massive cache of Valve data has reportedly leaked online, appearing to include Portal 2’s elusive beta build and a potential weapon from Half-Life 2: Episode 3

A reported 12-terabyte cache of Valve internal builds and assets from 2003–2013 has circulated online, purportedly including complete beta builds for Portal 2 and assets for Counter-Strike: Global Offensive and Left 4 Dead; the leak’s origin is unknown and some commentary claims the files were obtained via a publicly accessible endpoint rather than an active hack.
