medium.jpg The Portal games have been beautiful, haven't they? The first one presented a simple, clean aesthetic that worked as a great backdrop to the clever gameplay and snarky humor of Chell's battle of wits against GLaDOS. Then, last year, Portal 2 took Aperture Science's glistening white test chambers and destroyed them, letting players roam through the innards of Cave Johnson's company. And lo, it was glorious.

Now, everyone can see how Valve executed this big visual shift in Dark Horse's upcoming The Art of Portal 2. Announced tonight at the Emerald City Comic-Con, the 184-page hardcover book will feature concept art and completed vision, along with character sketches and commentary from writers, artists and other developers.

It's out on October 31st and no price has been announced yet. But, based on the scintillating art above—click the Expand button to enlarge—I'm going to say that The Art of Portal 2 will be worth whatever the price tag is. It's got pictures of space. Spaaaace!
