Leakers have assembled a nearly complete, playable version of Valve’s cancelled 2007 Portal prequel, F-Stop, by combining assets and other materials that appeared across recent leak activity. The reported build is said to include a large portion of the game’s content, though sources indicate some elements are missing, and the completeness depends on what has been recovered.
The outlets differ mainly in how they describe the provenance and timing of the materials. The Verge says most assets came from a major 12-terabyte leak reported this August, and that final missing pieces reportedly arrived via the Valve Cut Content Discord this week. Kotaku frames the story as the result of three separate Valve leaks being merged into a playable version. Both describe the release as a fan-accessible recreation rather than an official Valve release, and both emphasize the cancelled status of the original project.
