"Join the Bat and some teenage turtles as they try to save their cities from the baddest of the bad guys! New York City. The Teenage Mutant Ninja Turtles face the battle of a lifetime, fighting both the fearsome Foot Clan and their leader, the Shredder, and the alien forces of General Krang... which is exactly Krang's plan. Now a single dimensional warp can rid him of both of his greatest rivals at once. Gotham City. From the Penguin to Killer Croc to Ra's al Ghul and beyond, the caped crime-fighter called Batman already has his hands full protecting his city. Suddenly, a new enemy emerges-the Shredder and his ninja followers, transported to Gotham and unleashed upon an unsuspecting world. Now they're on the hunt for the technology that will help them return home...and conquer Gotham City in the process. But heroes come in all shapes, and the Dark Knight does not fight alone. As the Caped Crusader joins forces with Leonardo, Donatello, Michelangelo, Raphael and Master Splinter, can the Bat, the Rat and the Turtles take down the most vicious villains from two dimensions?"--
