Warner Bros. Games has locked in the date. LEGO Batman: Legacy of the Dark Knight launches worldwide for Nintendo Switch 2 on September 18, 2026 — and pre-orders are live right now for both Standard and Deluxe Editions. The same day also brings the Mayhem Collection DLC across all platforms, making September 18 the biggest day yet for one of 2026’s most acclaimed games.

What Is LEGO Batman: Legacy of the Dark Knight?
Developed by TT Games, LEGO Batman: Legacy of the Dark Knight is an all-new open world action-adventure game that follows Bruce Wayne’s epic journey to become the hero of Gotham City — from origin to legend. The story draws from decades of Batman films, television shows, comic books, and games, layered with the signature LEGO humour fans of the series know well.
The game is already available on PlayStation 5, Xbox Series X|S, and PC via Steam and Epic Games Store. The Nintendo Switch 2 launch fills the last major platform gap — and brings the Mayhem Collection along for the ride.
The Mayhem Collection DLC — Joker and Harley Quinn Go Playable
This is the headline addition. The Mayhem Collection DLC introduces Mayhem Mode, featuring The Joker and Harley Quinn as fully playable characters alongside a new story mission. The Sinister Pack adds seven new suits — one for each main game playable character — five new Batcave items, and a brand new Batmobile to traverse the open world.
Playing as the villains in a LEGO Batman game is not new to the franchise — it is one of the features fans have requested since the original LEGO Batman trilogy. Getting Joker and Harley as a full DLC mode with a dedicated story mission rather than a cosmetic-only pack is the right way to deliver it.
Nintendo Switch 2 Deluxe Edition — Everything Included
The Nintendo Switch 2 Deluxe Edition launches September 18 with the following content bundled in:
| Content | Details |
|---|---|
| Legacy Collection DLC | New suits, vehicles, and Batcave items inspired by Batman: Arkham, Batman Beyond, and a party music pack |
| Mayhem Collection DLC | Mayhem Mode (Joker + Harley Quinn), new story mission, Sinister Pack |
| Free LEGO Minifigure | Retro Video Game Batman minifigure — physical edition only, while supplies last |
| Pre-Order Bonus | The Dark Knight Returns Batsuit (Standard and Deluxe pre-orders) |
Current Standard Edition owners on PS5, Xbox Series X|S, and PC can purchase a Deluxe Edition upgrade to receive the Legacy Collection DLC immediately, with the Mayhem Collection DLC arriving September 18.
Unlock More With Warner Bros. and HBO Accounts
Players who create or link a Warner Bros. Games account unlock the Golden Age Batsuit — Batman’s classic outfit based on his debut appearance in Detective Comics #27 from 1939. Linking a Warner Bros. Games account with an active HBO Max account unlocks the Dark Knights of Steel Batsuit and the Black Lantern Batsuit, inspired by HBO’s Lanterns series.
For Indian users with an active JioHotstar or Jio OTT Pass subscription that includes HBO Max content, the account linking bonus is worth noting — though regional HBO Max account compatibility with Warner Bros. Games will need verification at launch.
LEGO Set Tie-Ins — Physical to Digital
Four new LEGO DC Batman physical sets include in-game digital content redeemable now. The LEGO DC Batman Logo set unlocks an exclusive gold Batsuit. The Batman Batmobile, Batman v Superman Batmobile, and Batman & Robin Batmobile sets each include an in-game playable version of the vehicle plus an exclusive gold variant. The gold Batsuit and gold vehicle variants are only available through LEGO set purchases — not available any other way.
This toys-to-game integration puts LEGO Batman in the same category as games that reward physical merchandise purchases with exclusive digital content — a model that tends to drive both game and toy sales simultaneously in India’s growing collector market.
NVIDIA DLSS Support — Optimised on PC From Day One
As noted in our NVIDIA Game Ready Driver 610.47 coverage, LEGO Batman: Legacy of the Dark Knight is one of the titles receiving day-one DLSS optimisation from NVIDIA — relevant for PC players running the game on RTX 50 Series hardware. The September 18 Mayhem Collection DLC will carry the same DLSS support forward.
