LEGO Batman: Legacy of the Dark Knight update 1.010 (1.010.000) released on September 17, 2026. This version introduces the Mayhem Collection DLC and a new challenge setting for the base game.
Absolute Difficulty and Mayhem Mode
Update 1.010 adds Absolute Difficulty, a free challenge level. This difficulty is available to all players regardless of DLC ownership.
For those looking for repeatable activities, the update introduces Mayhem Mode. Set across Gotham’s North Island, this is a time-limited mode where players can:
- Rob local shops and smash ATMs for studs.
- Engage in combat against Task Force X.
- Compete in timed runs to maximize destruction within the limit.
Mayhem Collection DLC and Sinister Pack
While the update is live now, the Mayhem Collection content officially unlocks for Deluxe Edition owners on September 18, 2026. This expansion features a new story campaign following Dr. Harleen Quinzel’s transformation and breakout from Arkham Asylum. The DLC story cutscenes utilize a 4:3 aspect ratio, a stylistic choice intended as a nod to Batman: The Animated Series.
Joker and Harley Quinn are playable in this campaign, featuring unique gadgets and the ability to attack while moving. The expansion also includes the Sinister Pack, which contains:
- 7 Character Suits.
- 1 Batmobile (Jokermobile).
- 5 Batcave Customization Items.
Gameplay Impact Analysis
The addition of Absolute Difficulty introduces high-skill content for veteran players. The introduction of move-and-attack mechanics for the new playable villains provides a more fluid combat experience compared to the standard character animations found in the base game. Players can expect the North Island area to become a primary hub for resource farming due to the density of smashable objects and ATMs in the new Mayhem Mode.
