The Final Hour of Portal 2 takes you deep within the top-secret office of Valve, creators of Half-Life, for an unvarnished, behind-the-scenes look at the making of its latest game Portal 2. Journalist Geoff Keighley was granted unprecedented “fly on the wall” access over the past three years to create this staggering 15,000 word multimedia experience. From the hush-hush Portal prequel that was shelved to the last minute scramble to complete the game’s story, readers will experience a gripping and dramatic tale brought to life with exclusive photos, videos, interviews, interactive experiences, and other surprises.

Wonderful Experience

Talk about a great read! Coupled with the interactivity of videos, polls, photos (including panoramas) and slideshows, this read became more like a universe to explore rather than another article. Though I knew nothing about the staff of Valve or the efforts it took to put the game together before this read, I now truly feel like I was a part of the experience. (Not a productive part, but none-the-less, a part.) I feel like I now share memories with those who've made one of my favorite games of all time.

Edit: This needs to be optimized for the new iPad.

A definitive glimpse into gaming's finest studio

Portal 2's polished and effortless presentation betrays a cringe-inducing drama to finish the most anticipated game of 2011. Over the course of fourteen in-depth chapters chronicling the lives of several key players, The Final Hours provides an exclusive portal into the Valve headquarters.

It took me about two hours to finish everything from cover to cover, watching videos, toying with interactive examples, and sifting through many galleries of unused assets and trashed ideas.

Absolutely necessary for any fan of Portal 2, Valve, game development, or the creation of art in general.

I got this on my new iPad. Really great! Already love it, and I'm just a few pages in. Would be nice if the text was updated for retina, its really weird to read, but I'll still do it of course.
