  "account": "Valve recently experienced a massive data leak, not due to hacking, but rather an accidental exposure of its legacy infrastructure. This resulted in the extraction of 12-13TB of old game content spanning from 2003 to 2013, effectively serving as a time capsule of the company's past projects. Among the discovered files are early builds of Left 4 Dead, Portal 2, and Counter-Strike: Global Offensive, as well as assets from canceled projects such as Half-Life 2: Episode 3's Weaponizer. The leak offers a unique glimpse into Valve's development process during the Steam2 era, showcasing the company's progress and experimentation in game design.",
  "summary": "Early builds of Valve games from 2003 to 2013 have been found in a 12TB archive pulled from the company's old servers. These pre-release versions act like time capsules, preserving the state of the game from before it underwent massive changes.",
