How long is Lego Batman Legacy of the Dark Knight? Well, the game's length and time to beat will vary depending on whether or not you want to do the story or whether you want to achieve 100% completion and get every collectible and hidden challenge in the whole game. As somebody who's done just that, I'll lay out the full time to beat for Lego Batman Legacy below, no matter what kind of playthrough and experience you're looking to have!
How long to beat Lego Batman Legacy of the Dark Knight
If you just want to do the story missions and finish the campaign in Lego Batman, it'll probably take you between 10 and 15 hours (assuming you don't do anything else).
Legacy of the Dark Knight's story is broken up into five chapters and you can replay missions as much as you like, and with it not being particularly difficult (unless you're playing on the highest difficulty). Of course, you can go back to missions to find collectibles, especially if you're out to get all the Lego Batman Legacy of the Dark Knight Red Bricks or similar.
How long for 100% completion?
If you want to do everything in the game - unlock every suit, find every collectible and complete every challenge - that will probably double the length of the game to about 25 to 35 hours, depending on player skill and focus.
Of course, Lego Batman is expected to get a new DLC in September 2026, which will expand the game accordingly (though we don't know by how much yet).
