The Art of Horizon Zero Dawn
I believe this came with my purchase of Horizon Zero Dawn on steam, which was honestly a fantastic experience. This PDF book is a short read as it’s 99% concept art, but it took me the better part of 30 minutes to get through the 53 pages because of how much I could zoom in on the art and how much there was to take in. I wouldn’t have bought this on it’s own, but as a value added digital book, it’s a neat read.
