Fantastic Four has 2 person COOP Play

I'm not entirely sure how it works but I saw this at Fry's yesterday and found at least one review on the net. The reviews say it has 2-person COOP play, letting you switch between the characters (i.e. the Fantastic Four) and "occasionally" some other players.
