"Take another trip to the past, to the time when Spider-Man unknowingly wore an alien symbiote as his costume! But this all-new blast from the past will take Spidey down the road less travelled ... into the supremely psychedelic Crossroads Dimension! And for those of you who know your Marvel history, that means that Peter Parker and his alien costume are on a collision course with none other than the mindless, rampaging Hulk! Meanwhile, with Spidey missing, the Black Cat enlists the aid of the Sorcerer Supreme! And ... is that a certain big, red dinosaur?! It's an unrevealed tale from Peter's symbiotic past"-- Provided by publisher
