Karakter, a German studio who have worked on games like Black Ops III, the last Killzone and Ryse, also got to once again help out on Game of Thrones' sixth season. Their art, like the episodes themselves, was epic. Here you'll see the visual origins of all the shit that went down. Dragons burning boats, battles between bastards, Dothraki storming the city gates, holding a door, the works.
You can see more of Karakter's art at their studio site. Note that while the art in this post itself is all Karakter's work, not all the designs necessarily are; Production Designer Deborah Riley (and her predecessor Gemma Jackson), her team and other groups like the costume designers all contributed to the overall look as well.
Fine Art is a celebration of the work of video game artists, showcasing the best of both their professional and personal portfolios.
