Ever wonder what went on during the development process behind Portal 2? Thanks to acclaimed US video game journalist, Geoff Keighley, now you can; last night during GameTrailers TV, Keighley released The Final Hours of Portal 2 as an iPad app for a mere $1.99. The Final Hours of Portal 2 promises an in-depth look at Valve's development process of the widely-acclaimed Portal 2. The app contains a plethora of content from interviews, exclusive photos, interactive material, and rounds out at about 15,000 words of informative details. Keighley also said the app would contain some surprises. As it appears, $1.99 to get a glimpse into one of the most highly anticipated games of the year, is a steal. If you're interested in buying the app, you can do so at iTunes directly on your iPad or via the web store link - click here.
