Famed DC comic book writers Geoff Johns and Marv Wolfman were tasked with establishing the backstory of the Universe and creating thousands of compelling story arcs, epic quests and action-packed, in-game events.
For example, players might be tasked with rescuing Batwoman from the fear gas that Scarecrow has unleashed in Gotham City's sewers, or battling Power Girl as they work with Lex Luthor to create an army of mutants out of Metropolis citizens.
