Lego Batman: Legacy of the Dark Knight is a 2026 action-adventure game developed by Traveller's Tales and published by Warner Bros. Games. It is the fourth installment in the Lego Batman video game series, and features an original story inspired by comic books, films and other media from the Batman franchise.
Legacy of the Dark Knight uses Unreal Engine 5 as opposed to TT Games' proprietary game engine, and takes heavy inspiration from Batman: Arkham, another series of Batman video games. Announced at Gamescom in 2025, it was released on PlayStation 5, Windows, and Xbox Series X/S on May 22, 2026, with a version for Nintendo Switch 2 scheduled for a later date.
