Over 12 terabytes of data, containing builds of every game uploaded to Steam between 2003 and 2013, has been leaked. We don’t know everything in the archives yet because of its massive size. But people have already dug up assets related to the canceled Half-Life 2: Episode 3, content cut from Portal 2, and a build of a game called F-Stop that’s set in the Portal universe but is built around a camera mechanic.
The leak also includes titles from third-party developers. Early versions of Call of Duty and Resident Evil installments have been dug up, as have builds of Mirror’s Edge, Batman: Arkham Asylum, and Dragon Age: Origins. And more is likely to come to light as people dig through the trove. But arguably the most interesting discoveries are related to Valve’s Portal 2. Sleuths have dug up deleted dialog that completely changes how you’ll look at Companion Cubes, alternative intro and GlaDOS sequences, as well as a version of the Weaponizer intended for Half-Life 2: Episode 3.
