With less than two weeks before Portal 2 is released, the marketing for the upcoming puzzle-shooter sequel from Valve is getting into high gear. Today the IGN web site announced that it will debut the official Portal 2 comic book on Friday and also showed some preview pages from the comic.

Valve created the comic book in-house and in an interview with Valve artist Michael Avon Oeming he said that the storyline will bridge the gap between Portal 1 and 2 and will also feature a "much-rumored yet never seen character." The comic, while a collaboration between several Valve team members, will be mostly written by Ted Kosmatka and drawn by Valve artist Andrea Wicklund (she'salso the owner of the hand that was used in the box cover for Valve Left 4 Dead series).
