Atlus today unveiled the hardcover, limited pre-order bonus art book for Game of Thrones.The publisher says it's only available from select retailers while limited supplies last and "stands as one of Atlus' finest bonuses to date." The book offers sixty-four color pages of sketches, renders, photos, and screenshots from the game with text and commentary from the developers. The PC version will be digital-only.The book also includes rare items, like a signed portrait of the development team. "Everything about this premium art book is above and beyond the typical pre-order bonus, and all at no additional cost to the customer," Atlus said."Its larger dimensions, page count, hardcover binding, and exceptional print quality are more in line with what fans would expect from a Deluxe Edition extra or a separate purchase."Game of Thrones is coming to Xbox 360, PlayStation 3, and PC May 15.
