LEGO Batman: Legacy of The Dark Knight was a hit when it arrived earlier this year, blending the free-flow combat and open world exploration of the Arkham series with a lighthearted LEGO tone. With the arrival of the Mayhem Mode DLC, the Caped-Crusader is out and the Clown Prince of Crime is in! The Joker and Harley Quinn frontline this all new DLC drop, and IGN got to speak level designer, Tim Spencer, and advanced designer, Chris Payne from TT Games, about the unique challenges associated with designing for committing crimes rather than stopping them. We also got the inside track on what media was used to flesh out The Joker outside of his on-screen appearances, the changes between him and Batman from a gameplay perspective, and unique additions to the Switch 2 edition! If this sounds like a barrel of laughs, you'll be able to play Lego Batman Legacy of The Dark Knight Mayhem Collection when it drops on September 18th for PlayStation 5 (PS5), PC (Steam), Nintendo Switch 2 and Xbox Series X|S.
