LEGO Batman: Legacy of the Dark Knight - Play as The Joker and Harley Quinn Starting Today

Four months have gone by since LEGO Batman: Legacy of the Dark Knight released and gamers who have unlocked the Mayhem Collection can finally dive into some villainous activities starting today.

September 18 is a big day for LEGO Batman fans with the long-awaited arrival of the Mayhem Collection and the new Absolute difficulty option. The base game launched to very positive fan and critic reactions and the community has been looking forward to the first batch of add-on content for months.

Today also marks the release of the Absolute Difficulty, which is designed to be even more challenging than the Caped Crusader and Dark Knight options, requiring greater skill, awareness, and precision in combat.

The Absolute Difficulty is included as a free update for all players.

At the moment, no additional content has been announced beyond today’s additions. Depending on the sales and reception of the Mayhem Collection, it will be very interesting to see whether the experience continues to grow in the future or if this will be the complete gameplay experience.

Additionally, Nintendo Switch 2 players are finally able to join the fun with the official launch of the game on the Nintendo console.
