I've always had a lot of mixed feelings when it comes to the Mirror's Edge video games as I enjoy them immensely yet at the same time feel that they could have been a lot better, especially Mirror's Edge Catalyst which didn't feel finished. As well as the games there are a number of books and comics available.
The Art of Mirror's Edge Catalyst is a beautiful book containing stunning images taken from the game as well as concept art, promotional art and illustrations of in-game props such as Faith's running shoes for instance. There's also a lot of art from the original Mirror's Edge too.
The text is brief and written in the style of collective first-person with the game creators known as DICE explaining their love for the game whilst showing the related art work. Even at 200 pages long it can be read in one sitting but re-enjoyed over and over again looking at the stunning pictures.
The book is available in hard back and measures approximately 12 inches x 9 inches (30cm x 23cm). It's published by Dark Horse Books.
In summary I'd say this book is a must for all Mirror's Edge fans yet I can't help but feel it over praises the game showing the potential of what the game could have been rather than what the game turned out to be. I suspect the book was compiled while the game was still in production.
