Community Reconstructs Playable Build of Valve's Cancelled 2007 Portal Prequel F-Stop
A fully playable version of F-Stop, Valve's cancelled 2007 prequel to Portal, has emerged online after community members combined three separate leaks. The game, which featured a camera-based puzzle mechanic, was scrapped after poor playtest results but contributed elements to Portal 2. While the build is reported to be 99% complete, it lacks official release status and some polish.
