Valve’s cancelled Portal prequel F-Stop is now playable after leaks
A community has assembled a playable version of F-Stop, Valve’s cancelled 2007 Portal prequel, from assets, source code and map files leaked in separate batches. Players describe the build as about 99% complete, with some textures and dialogue missing, according to Kotaku; Valve has not commented.
Bottom line — F-Stop’s camera-based puzzles can now be played, nearly 20 years after Valve shelved the project.
