"Hopefully, because he's busy." Trophy in LEGO Batman: Legacy of the Dark Knight

• Riddler and Cluemaster puzzles: puzzle boxes around the city and the puzzle rooms they open
• Falcone Fortunes: Catwoman's safe-cracking jobs
• Ivy's plants: giant plants to destroy
• Escaped zoo animals to tag with a tracker

• AR Trials: Lucius Fox's driving, traversal and combat courses
• WayneTech Caches, Subwayne stations and radio towers

Leave them until after the story, when every character is available.

1. In each district, hack its radio tower as Batgirl. It marks every side activity and collectible in the district on the map.
2. Open the map with Touchpad and point at a district. The list beside it shows what is left there. Clear the list of every district.
3. Falcone Fortunes and the puzzle rooms open one after another. If a district's list shows something you cannot find, finish the same chain in the other districts first.
