Twenty-two years ago, Geoff Keighley was in college when he visited Gabe Newell and Valve Software to write The Final Hours of Half-Life. Now, over two decades later, Keighley returns to Valve for The Final Hours of Half-Life: Alyx. This 25,000 word multimedia experience gives readers an unprecedented and unvarnished look at the past decade inside Valve.

From the revelation of surprising canceled projects to never-before-seen images, photos and video, The Final Hours dissects Valve's creative process and candidly explores the development history of Half-Life: Alyx. This interactive storybook does not use or require a virtual reality headset. It merges a 25,000 word traditional story with 3D video game technology to give customers a fly-on-the-wall perspective of Valve's creative process.
