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 games story, readers will experience a gripping and dramatic tale brought to life with exclusive photos, videos, interviews, interactive experiences, and other surprises.
