Source: HalfLife2.netHalfLife2.net has put online a great review of the Prima Games book Raising the Bar. The review includes exclusive never before seen images of the book. Here some words:
Half-Life 2: Raising the Bar was originally designed as a full “Making of...” book that was to include a full history of Valve, their previous titles and the turmoil they went through to get Half-Life 2 on the shelves. Not only was it to include a lot of narrative points written by David Hodgson, but it was also to include thorough discussions with many of the staff at Valve. At first I was originally disappointed that this was all going to change but after reading the new version, I can understand why they made the change as Raising the Bar is now essentially a 300-page directory of concept art and original scripts most of which have never been seen before. Alongside the artwork you’ll still see some narrative and comments from Valve staff explaining aspects of the art pieces on the page.The full, detailed review can be found here.
