During a video game panel at Emerald City Comic-Con last weekend, Dark Horse Comics announced that they would be publishing a new concept art book for developer Valve’s hit sequel, Portal 2.

The book, titled The Art of Portal 2, gives fans a look at the game from initial concepts to the final product, with added insight from both artists and writers who have worked on the Portal game series. At 184 pages, fans will get their fill of mostly never-before-seen art, including looks at the Aperture Science facility, characters such as Chell, and the design process of Valve.

The Art of Portal 2 will hit store shelves on October 31, 2012.
