LEGO Batman 2 builds on the classic LEGO Batman by allowing players to take on the role of other D.C. Comics super heroes, such as Green Lantern, Wonder Woman, and Superman. It was also the first LEGO game to feature voice acting for the characters, instead of using mime routines and movie references to get the story across.
The Wii U port of LEGO Batman 2 will be using the Wii U GamePad to display an interactive map of Gotham City, and players will also be able to select characters on the GamePad. Players can also play the entire game on the tablet controller alone, or with another player that can have the TV to themselves. That's a nice feature for everyone who knows one of the most frustrating things about LEGO video games is sharing same screen with a partner.
