Lego Batman: Legacy of the Dark Knight adds Joker and Harley Quinn content on September 18, alongside a free Absolute difficulty update.
Game Informer reports that Lego Batman: Legacy of the Dark Knight's Joker and Harley Quinn DLC will launch on September 18. WB Games has also revealed a free Absolute difficulty update for the same day, giving every version of the game access to a challenge level above Dark Knight.
According to Game Informer, the paid content includes a new level focused on the two villains, additional activity in Mayhem Mode, and Joker-inspired suits for the game's seven playable characters. The release date also matches the launch of the Switch 2 version of Lego Batman: Legacy of the Dark Knight.
The announcement gives players two separate reasons to return to Gotham. The DLC expands the roster and adds villain-focused scenarios, while the free update targets one of the game's more important long-term questions: whether its highest difficulty can provide a meaningful challenge after the main story is complete.
What the Joker and Harley Quinn DLC includes
Game Informer says the new content will give Joker and Harley Quinn an exclusive level built around an escape from Arkham Asylum. The scenario has the pair arranging a breakout before taking their celebration into Gotham City. The source describes it as a dedicated story-style mission, but the available report does not confirm its length, structure, or whether it can be played cooperatively.
The villains will also be playable in Mayhem Mode, according to Game Informer. In this mode, Joker and Harley Quinn move through Gotham while destroying landmarks, completing challenges, and fighting Task Force X members. The named opponents are Deathstroke, Killer Croc, Captain Boomerang, Deadshot, King Shark, Polka-Dot Man, and Katana.
Mayhem Mode adds a time limit to each run. Players must return to the Amusement Mile before the timer expires, or Batman and Robin will hunt them down, Game Informer reports. That structure gives the DLC a different rhythm from a straightforward level. Instead of simply clearing a fixed encounter, players will have to balance destruction, objectives, combat, and the return trip.
The source also confirms new outfits for the base game's seven playable characters. Each will receive a Joker-inspired suit, while Batman can use the Bat Who Laughs costume. Game Informer does not identify the other suits or explain whether these outfits alter abilities, statistics, animations, or only appearance. At present, the confirmed information supports treating them as cosmetic additions rather than assuming gameplay changes.
Game Informer reports that the DLC is included with the deluxe edition of Lego Batman: Legacy of the Dark Knight. Players who own the base game can upgrade for $24.99, according to the report. The supplied information does not confirm a separate standalone price for the content, so that detail remains unconfirmed.
The release date for the DLC is September 18. Game Informer says the free Absolute difficulty update will arrive on that date as well, and that the update will apply to all versions of the game. The report does not state whether the new difficulty will be available from the beginning of a save, require story progress, or affect only new playthroughs.
September 18 is also the launch date for the Switch 2 version of Lego Batman: Legacy of the Dark Knight, Game Informer reports. The article does not provide performance details, visual comparisons, save-transfer information, or a list of features specific to that version. Those are practical questions for Switch 2 players, but they cannot be answered from the current announcement.
For existing owners, the important distinction is that Absolute difficulty is free while the Joker and Harley Quinn content is tied to the deluxe edition or its $24.99 upgrade. This separates the game's challenge update from its new characters, level, Mayhem Mode content, and outfits. Players interested only in a harder campaign will not need to purchase the DLC based on the information currently available.
The paid expansion is the more visible part of the announcement, but the free difficulty update may have the broader effect on how players revisit the game. Game Informer identifies Absolute as a difficulty level above Dark Knight, making it the new hardest option in the game.
That change matters most for players who have already completed the campaign or found Dark Knight insufficiently demanding. A new highest setting can give familiar combat encounters a reason to be replayed, particularly if the game rewards players for experimenting with its character abilities and gadgets. This is analysis rather than a confirmed description of the update: WB Games has not provided the specific changes that make Absolute harder.
Without those details, it is too early to know whether Absolute will change enemy behavior, damage values, health, encounter composition, resource availability, or another part of the game's balance. A higher label alone does not establish how the mode plays. The first useful evidence will be footage or patch documentation showing what differs from Dark Knight.
The timing is still notable. Players will receive the new difficulty on the same day as the villain expansion, so the two additions could reinforce each other for returning players. The Joker and Harley Quinn missions may provide fresh content, while Absolute could offer a reason to approach that content and the main campaign with more demanding settings. Whether that combination works will depend on the actual tuning of the mode and the amount of replay value in Mayhem Mode.
Game Informer's report suggests that the expansion is designed around a compact villain partnership rather than a broad roster increase. Earlier Lego Batman games were known for large playable casts, but the source notes that Legacy of the Dark Knight places more emphasis on individual members of Batman's group. The Joker and Harley Quinn therefore add two characters while preserving the game's focus on character-specific gadgets and abilities.
That approach could make the new pair feel more distinct than a simple character swap. The available information confirms their exclusive level and their role in Mayhem Mode, but it does not explain how their abilities work or how they differ from the heroes. Players should watch for gameplay demonstrations that show whether Joker and Harley Quinn have separate toolsets, complementary mechanics, or special interactions with the new challenges.
Mayhem Mode also appears to be the part of the DLC with the clearest repeat-play structure. Its timed runs, landmark destruction, optional challenges, and Task Force X encounters create several competing goals. The need to return to the Amusement Mile before Batman and Robin arrive adds a defined endpoint to each attempt. That could make the mode appealing to players who enjoy optimizing routes and completion times.
However, the report does not confirm how many Mayhem Mode scenarios are included, whether objectives are randomized, or whether the mode supports solo and multiplayer play. It also does not explain how the timer is set or what happens when a player fails to return in time beyond Batman and Robin hunting the villains down. Those missing details will determine whether Mayhem Mode feels like a substantial activity or a shorter side experience.
The costumes may provide a simpler reason to return. Seven base-game characters receiving Joker-inspired outfits gives collectors an additional set of unlocks to pursue, and Batman's Bat Who Laughs costume is the only specific suit identified in the report. There is no confirmation that the outfits include new abilities or that they are earned through particular challenges.
The announcement confirms the release date and broad content outline, but several practical details are still open. WB Games has not, in the supplied material, explained the DLC's total mission count, the duration of its exclusive level, or whether Joker and Harley Quinn can be used throughout the base campaign. The report also does not confirm whether the expansion is available separately from the deluxe upgrade.
Absolute difficulty needs similar clarification. The new mode is confirmed as harder than Dark Knight, but the source does not describe its rule changes or whether it applies to every activity in the game. Players will need more information before they can judge whether it addresses concerns about the original difficulty curve or simply adds a tougher numerical setting.
Switch 2 owners have additional unanswered questions. Game Informer confirms that the version launches on September 18, but the available report does not give technical specifications or explain how it relates to other versions. Details about resolution, frame rate, loading, cross-progression, and upgrade paths remain unconfirmed.
The next evidence worth watching is official gameplay that demonstrates the Arkham Asylum level, Mayhem Mode's timed structure, the villain abilities, and the Absolute setting in action. Patch notes would also help establish exactly what changes in the free update. Until that information arrives, the confirmed picture is straightforward: September 18 brings paid Joker and Harley Quinn content, free Absolute difficulty for all versions, and the Switch 2 release, while the depth of each addition remains to be demonstrated.
