From the dustjacket:
Journey is an interactive parable about the passage of life with an awe-inspiring, minimalist design that transcends language. Players control a robed figure wandering over glittering sands toward a monumental mountaintop in the distance. Their journeys take them through the history of a fallen civilization, exploring richly textured ruins of breathtaking and heartrending beauty.
Readers can view animated 3D renderings of Journey art directly from this book using their smartphones or tablets as augmented reality brings many of the game's images to life.
The author of this book, Matthew Nava, served as Journey's art director. The Art of Journey provides a unique insight into a three-year evolutionary process that led to the mysterious and beautiful world of Journey.
