Portal Prequel F-Stop Leaks Online in Almost Fully Playable Form

Community members combined three separate leaks to reconstruct the cancelled Portal prequel, which players say is about 99% complete.

  • Leakers have compiled a playable version of Valve's cancelled 2007 Portal prequel, F-Stop, after combining fragmented data from multiple unauthorized leaks into a functional build.
  • Over the past 48 hours, the Valve Cut Content Discord server received the final source code and map data, completing the missing pieces needed to assemble a near-complete version.
  • Developed during Valve's 2007 "Directed Design Experiments", F-Stop features an experimental Aperture Science camera mechanic that captures objects as Polaroid-like photos for puzzle-solving.
  • YouTube playthroughs show the game is "99 percent complete", though it remains missing some textures and dialogue; the campaign runs largely stable at under one hour.
  • Valve ultimately scrapped F-Stop, reworking some mechanics into Portal 2, and currently shows no indication of an official release for this prequel.
