LEGO Batman: Legacy of the Dark Knight may already have its first post-launch expansion revealed through newly leaked information connected to the game’s files.
According to the reported leak, the upcoming DLC is expected to revolve heavily around Gotham’s villains and could introduce new playable characters, additional missions, and a separate chaos-focused gameplay mode.
The expansion is reportedly tied to something called the Mayhem Collection, which appears to place major focus on characters like Joker and Harley Quinn. Several other DC villains have also allegedly been discovered within the leaked content files.
Reportedly leaked characters include:
- Deadshot
- King Shark
- Captain Boomerang
- Peacemaker
- Clayface
- Scarecrow
Because of the lineup, many fans believe the DLC may take inspiration from Suicide Squad-related stories and themes, though nothing has been officially confirmed yet.
The leaked information also points toward a brand-new side mode centered around causing destruction and chaos throughout Gotham City, potentially offering a different style of gameplay compared to the main campaign.
Interestingly, parts of the DLC had seemingly already been hinted at through Deluxe Edition descriptions before the leak surfaced online, suggesting post-launch content plans were already in motion behind the scenes.
At the moment, neither Warner Bros. Games nor the developers have officially confirmed the leaked details, meaning some content could still change before release.
With the game already receiving strong early impressions from critics, the possibility of major villain-focused expansions is now generating even more excitement among DC fans.
So, which Batman villain would you most want to see added to the game in future DLC?
