Oh tome, neither secret nor old, what information lies between the cover's fold? Whose to say if this promo material, reportedly obtained at a GameStop manager conference or a Best Buy Gamer's Day in Toronto if we're to "BELIEVE" NeoGAF, actually ruins Ubisoft's Assassin's Creed
for you. It ultimately depends what you consider spoilers.
Opinion: It doesn't contain any "Darth Vader is your father" level reveals, opting for more "Porkins dies in the Death Star fight" style non-spoilers. However, if you want to maintain your Assassin's Creed
story virginity, you better steer clear of sidcuddlesGHIII's Photobucket account, which contains the entirety of the comic.
