Half-Life: Alyx - Final Hours

This interactive storybook documents Valve’s development work over the decade leading up to Half-Life: Alyx. You read Geoff Keighley’s account of the company and the making of the game through a mix of text, images, video, and interactive media.

As you move through the material, you can solve interactive puzzles to unlock concept art and images, inspect 3D assets, and create headcrab sound effects from development audio files. An interactive tour lets you explore Valve’s development area.

The chronicle also includes a timeline of Valve’s software and hardware projects, prototype footage, information about canceled projects, and an interview with Rhys Darby. It is designed for standard screens and does not require a VR headset.

Players who enjoyed the experience often praise its behind-the-scenes look at Valve, especially the development history, concept art, footage, and stories about the people involved. Several also appreciate the interactive elements and presentation. Some reviewers find it too reading-heavy to feel like a traditional game, and individual complaints mention navigation problems and the lack of Russian translation.
