Warner Bros. Games announces LEGO Batman DLC and Switch 2 release

Warner Bros. Games and TT Games have announced the Mayhem Collection DLC for LEGO Batman: Legacy of the Dark Knight, scheduled for release on September 18, 2026. The expansion will be available on PlayStation 5, Xbox Series X|S, PC, and the Nintendo Switch 2.

The DLC introduces The Joker and Harley Quinn as fully playable characters. The Joker features an agile combat style using a Paintball Pelter and boxing gloves, while Harley Quinn utilizes a hammer, her hyenas Bud and Lou, and a confetti-filled Fun Gun. Content includes a new story mission centered on an Arkham Asylum breakout, a timed Mayhem Mode where players cause destruction across Gotham City, and the Sinister Pack, which offers themed outfits for the Bat-family inspired by DC comics.

Additionally, a free update will be released for all players on the same day, introducing the “Absolute” difficulty mode, designed to be the game’s most challenging tactical and combat experience.
