Sony announced an extra gift for the Limited Edition Horizon Zero Dawn in Japan what you can get with the package and even with the download version (just in digital form) of the game. If you choose the Limited Edition you will get an extra artbook called “THE ART OF Horizon Zero Dawn” which will be full with unpublished illustrations and pictures from this strange world where machine beasts dominate the earth.

Sony planning to release later some sample pages from the book but until that you can pre-order your game from your local store or from the Japan PSN: PlayStation Store product page
