A massive cache of internal builds from Valve has reportedly leaked online, including beta builds of several classic Valve titles and possible weapons from Half-Life 2's cancelled third episode.
The leak, which began circulating on Saturday and comes from an unknown source, includes 12 terabytes of data currently being sifted through by data miners. The files are dated from a ten-year period between 2003 and 2013, and include builds and assets of many Valve projects across that timespan.
