Fabulous!
This book is filled with great concept art on the characters, environment, enemies, weapons and vehicles. The sketches are fantastic.
If you loved Halo, or you are into Concept Design, you should absolutely buy this book!

Very Inspirational!
Maybe I'm a little biased because I myself am a Concept Artist working in the game industry but this book is all kinds of awesome.

Beautifully laid out, starting with character art, enviros and moving on to multiplayer and marketing. there's so much in this book to appreciate, even if you're not a fan of the Halo games themselves.

The story and thought that goes into each design is amazing and a great inspiration to anyone with an interest in this lesser seen aspect of the game industry.

If there were a downside to this book it's that they could get more into the pages (because I know there's a lot more out there that's not being shown here).
