Valve has launched a Portal comic drawn in a graphic novel style that explains more about the Portal universe and bridges the gap between the first game and its upcoming sequel. Lab Rat is produced in-house with Michael Avon Oeming who is the co-creator of popular series Powers. Art is by Andrea Wicklund in collaboration with Oeming, Ted Kosmatka, Erik Wolpaw, Jay Pinkerton and Half-Life 2 / Portal co-writer Chet Faliszek. Released in parts, Lab Rat fans can share a link to the comic to Facebook to drive conversation within their fans and followers.
