Comic Book Resources outlines plans for a 304-page hardcover compilation of Valve's game-related comics in the works at Dark Horse for release November 16 (thanks Kotaku). Here's word on what to expect:

For fifteen years, Valve has defined the cutting edge of video games. Now, Valve joins with Dark Horse to bring three critically acclaimed, fan-favorite series to print, with a hardcover collection of comics from the worlds of Left 4 Dead, Team Fortress, and Portal. With over three hundred pages of story, Valve Presents: The sacrifice and other Steam-Powered Stories is a must-read for fans looking to further explore the games they love or comics readers interested in dipping their toes into new mythos!
