Joker and Harley just stole the spotlight.
The Mayhem Collection DLC for LEGO Batman: Legacy of the Dark Knight lands September 18 on Xbox Series X|S. You drop the cape and play the other side of Gotham.
It’s a love letter to Batman: The Animated Series. Harley’s origin starts as Dr. Harleen Quinzel. Cutscenes drop into 4:3.
There’s a shop called Sorkin’s Gems — a tribute to Arleen Sorkin, the original Harley. Then the Arkham breakout turns into a going-away party Gotham won’t forget.
After the escape, they set up shop under the Funhouse at Amusement Mile. Expand it. Decorate it. Make it theirs.
