Portal 2: The Final Hours Makes The Leap From IPad To Steam

Geoff Keighley's interactive app on the development of Portal 2 is no longer an iPad exclusive. Portal 2: The Final Hours is now available for Mac and PC via Valve's Steam service for $US1.99 USD.


    Hah, it's a poor quality port!

    I spent $5.99 on it on the iPad when it came out, so now I feel screwed.

      Dude, you spent 4 dollars more. On a much nicer version of it. I would of been happy paying 10 for it on iPad, it was a fantastic book and really well designed.
