Lego Batman Legacy of the Dark Knight: Key Item Locations & Interactive Tracking Guide

The most expansive guide category in our LEGO Batman: Legacy of the Dark Knight Completion Hub belongs to Key Items — the interactive environmental objects that don't fit neatly into any single collectible type but matter for story progression, side quests, and 100% completion.


From security cameras to be disabled with a Batarang inside the Iceberg Lounge, to scattered Poster Pieces across Gotham's rooftops, to a ghost only visible through a camera lens — this guide tracks every one of them.


All Key Item locations are, therefore, included on our LEGO Batman: Legacy of the Dark Knight interactive maps, with instructions on how to handle them.


LEGO Batman Key Item Type 1: Wanted Poster Pieces


Every open-world district except Gotham Village and East End has a Wanted Poster bulletin board — interact with it to reveal three scattered Poster Pieces in the surrounding area, then collect all three, assemble the poster, and track down the named criminal in the open world to make the arrest. There are 7 Wanted Posters across six districts:



Each completed poster rewards 2 WayneTech Chips. Completing all 7 unlocks Batman's Knightmare Suit and Jim Gordon's Batsuit as milestone rewards.


All poster board locations are revealed by activating the district's Radio Tower with Batgirl.


LEGO Batman Key Item Type 2: Bruce Wayne's Gray Ghost Costume


Four pieces hidden across Wayne Manor Grounds as the opening prologue's collectible challenge:


  • Bruce's Cape — on the statue in the middle of the garden (collected via the Detect ability tutorial)
  • Bruce's Goggles — inside the large chest in the garden house
  • Bruce's Hat (first) — inside the large W-shaped bush (smash it)
  • Bruce's Hat (second) — the hat flies to the top of the garden well; jump on the well to catch it


LEGO Batman Key Item Type 3: Batcave Equipment Unlocks


Three items inside The Batcave found and activated during the Spelunking Mission:


  • Batclaw — in breakable crates in front of the Batcave elevator, story-mandatory
  • Generator — upper cave floor; grab the blue battery nearby and insert it to activate
  • Scanner — upper cave floor; place the bear on the scanner and interact with the computer after the generator is running


LEGO Batman Key Item Type 4: Case of Waylon Jones Evidence


Investigation clues for the Case of Waylon Jones side quest tracked in Gotham Village — Robinson Park.


Find the Citizen near Harvey Bullock (speaks to start the first case), a Hot Dog in the red-lit alley (UV Vision reveals tracks; follow them with Robin's battle staff), and a Fishing Pole by the water (inspect for case evidence).


LEGO Batman Key Item Type 5: Story Mission Interactive Objects


The largest subcategory — the environmental objects that facilitate story progression across every linear chapter.


These range from Security Cameras (disabled with Batarang), Yellow Mechanisms (stopped with Gordon's Foam Sprayer), Shuriken Targets (hit in sequence), Moveable Carts (pushed), and Food Plates (loaded in the Iceberg Lounge kitchen).


None are missable — all missions are replayable from the Batcomputer.


The Gentleman Ghost: An East End Easter Egg


One Key Item stands entirely apart from every other: the Gentleman Ghost in East End — Amusement Mile.


Found near a white pile of goo on the western side of the district, it's completely invisible during normal play — only accessible through Photo Mode (opened from the menu).


Stand in the white goo, open Photo Mode, and photograph the ghost that appears only in the viewfinder to unlock the "Paranormal Investigator" challenge.
