Game Description:There are heroes, and then there are superheroes. They don't come any bigger than the members of the fabled Justice League, especially those assembled here on the PSP. Play as the biggest names in the superhero biz, all in the same game. Superman, Batman, Wonder Woman, Green Lantern, The Flash, Zatanna, and Martian Manhunter are ready to take on the most notorious DC Comics bad guys. You can even unlock up to six more heroes. An engaging storyline filled with cut scenes and in-game super-banter and secret PSP-only levels only add to the fun.
