LEGO Batman: Legacy of the Dark Knight will offer players a Gotham City that’s even larger than the one seen in Batman: Arkham Knight, according to a new report. Serving as the first major LEGO Batman game since 2014’s LEGO Batman 3: Beyond Gotham, this new entry from TT Games looks set to deliver the most ambitious LEGO superhero adventure yet.
Revealed at Gamescom
Warner Bros. Games officially unveiled LEGO Batman: Legacy of the Dark Knight during Gamescom with a humor-filled trailer that instantly caught the attention of both Batman and LEGO fans. The game’s reveal sparked comparisons to Rocksteady’s Arkham series, thanks to its darker Gotham setting and nods to iconic Batman films. With a 2026 release window, anticipation is steadily growing as more details about the project surface.
A Bigger Gotham Than Arkham Knight
The latest rumor comes from the Twitter account LEGO Games News, which claims the game will feature four distinct islands in its open-world Gotham City. Among them, the South Island will reportedly be the largest. By comparison, Batman: Arkham Knight offered three islands — Bleake Island, Founders Island, and Miagani Island.
This makes LEGO Batman: Legacy of the Dark Knight Gotham even more expansive than its Arkham counterpart, offering new opportunities for exploration, missions, and hidden secrets.
Adding to the excitement, the Batmobile is confirmed to play a role in navigating Gotham’s vast streets, with mechanics described as being “similar to Arkham Knight.” This suggests a mix of action-packed driving and puzzle-solving gameplay across the city.
Why This Matters for Fans
Arkham Knight was praised for its atmospheric and detailed Gotham City, which stood as the largest in the Arkham franchise. For TT Games to expand on that scale in a LEGO title is a bold move. A fourth island could mean:
-
More variety in districts — from industrial zones to high-rise skylines.
-
New points of interest tied to Batman’s lore.
-
Expanded character roster with potential appearances from fan-favorite villains and allies.
Ultimately, much will depend on how TT Games uses the extra space to balance story, exploration, and the trademark LEGO humor.
With LEGO’s proven family-friendly appeal and Batman’s enduring popularity, LEGO Batman: Legacy of the Dark Knight has the potential to bridge the gap between fun co-op play and open-world depth when it arrives in 2026.
