So I didn't actually purchase this book. I won it from a YouTube contest and the book is signed by Frank O'Connor (Former Content Manager at Bungie who joined Microsoft and became the Creative Director for 343 Industries). I have played every Halo game to date, including Halo 1-3, Reach, ODST, and Wars. I'm a huge fan of the series and can't wait for Halo 4 and the Reclaimer trilogy. Hopefully even a Halo movie. This book is 192 pages.
This is my first art book so here is my perspective. Playing every game in the Halo series, I really didn't know or understand how concept art and sketches start and what processes the creative teams use to make them come to life. I have a new perspective on what goes into making characters, weapons, vehicles, planets, aliens, etc. basically everything that is in a game.
This book shows everything from the Halo series. When I say everything, I mean original sketches all the way to their evolved and final forms. Art from every game up to Halo Reach. Master Chief, Cortana, The Flood, The Covenant forces including grunts, brutes, elites, hunters and jackals, vehicles including the Warthog, Tank, and Covenant vehicles, all weapons and armor, ships including the Pillar of Autumn, and all world settings including Reach, Ring World, Earth, etc.
While I am sure there are more extensive art books for Halo (including the Halo encyclopedia), this book is very detailed and the images are truly vivid. If you are a fan of Halo or into the conceptual art in video games, this book is for you.
