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.

It's an advert why are we paying for it?

Essentially this is just an advert for a game, OK its pretty slick but still an advert with lots of pictures of hairy geeks, please Apple why are you letting them charge for this App???

Bit of a rip off.

I would give it zero stars if I could!
