This review is from: Deus Ex: Human Revolution - Collector's Edition Guide (Hardcover)
This special guide is almost as perfect as the game it covers :)
The hardcover is sleek and solid, the contents are varied, well ordered, and the graphic design is pretty cool. The info has good depth (but watch for spoilers!) so you can see the perfect route if you play in stealth, e.g.
At the end there are around 30 pages of the "making of", which is very interesting, but if you saw the material of CGSociety, there's nothing really new... maybe it could have been great to have some special and exclusive interviews or concept arts, but...
A must have for a DX fan anyway!
