  "account": "F-Stop, a prequel to the popular Portal series, has been fully playable thanks to the efforts of the community. This version has been compiled from a massive leak containing over 12 terabytes of Steam data, which was released in August. The leak included various assets for F-Stop, as well as data from early versions of Left 4 Dead, Portal 2, Half-Life, and more. The source code and map data were later leaked to Valve's Cut Content project Discord server, which was then combined with the previous leak to create an almost fully finished version of the game.\n\nAlthough the game is largely stable, it is missing textures and dialogue. However, users can still experience the unique camera mechanic that allows for capturing and modifying real-world objects. This playable, albeit incomplete, version of F-Stop may be the closest thing to an official release, as there is no indication from Valve of any further development on the project.",
