How to Replay a Mission

In case you didn’t find all collectibles in the first story playthrough, don’t worry. You can still get it. Play the story to Mission 6: Shreck’s Department Store, where you restore the Batcave.

Then, travel to the Batcave and interact with the computer at the top, next to the red batphone. Here you can select the mission you would like to play again.

You will also see the status. If the box is ticked: Congratulations, you’ve found all the collectibles in this mission. If not, there is still work to be done!

Batcave Trophy: League Banners

Find and destroy 5 League Banners in The League of Shadows Returns, Mission 16, to receive the Batcave Trophy: League Banners.

Red Brick: Bats

After the sewer section, go upstairs and disable the cameras with the console. Behind the console are two tumblers and the Red Brick. Charge up the dumpster truck with Nightwing’s staff, then use a Hackarang to move it. Now you can safely reach the Red Brick.

WayneTech Caches

Investigate the Tricorner Docks in the Tricorner district.

Tricorner Docks location - Mission 16 - Lego Batman Legacy of the Dark Knight camzillasmom.com

At the end of the docks, the same place where you’ve been in Mission 3: New Beginnings, is a pile of garbage with a blue flower, where Batman can use his UV Vision. Follow the particles to a container with the League of Shadows’ insignia.

UV Vision Seeing is Believing - Mission 16 - Lego Batman Legacy of the Dark Knight camzillasmom.com
Container with Insignia - Seeing is Believing - Mission 16 - Lego Batman Legacy of the Dark Knight camzillasmom.com

Move the blue container cart aside to get access to the door. Then, switch to Talia and use her Ninja Dash ability to get past the door to pull the lever.

Now Batman can pull the League’s container open with the Bat Claw, and the contents can be investigated: A ticket to the Tunnel of Love on the table.

Ferris Wheel Puzzle Piece

Use the ticket on the slot at the Tunnel of Love and investigate the door inside. The door is missing three puzzle pieces. Head back outside and grapple over the Tunnel of Love building to find a building with a wrecked machine inside. It is missing three cogs. Two of them are in the cafeteria area to the left of the machine. The big one goes right next to the lever, the small one right after the big one.

The third cog is at the blue lockers. Place it in the third position and turn the machine on. This will turn on the Ferris wheel. The missing piece is in one of the cabins.

Rollercoaster Puzzle Piece

For the second puzzle piece, head over to the rollercoaster. The rollercoaster carts are locked inside the cage. As Talia, pull the doors open, then switch to Batman to use the Bat Claw. The carts will jump onto the rollercoaster tracks, and the two can retrieve the puzzle piece.

Ice Cream Parlor Puzzle Piece

The third piece is in the ice cream parlor. There is a wall Batman can blow open with the Explosive Spray. In the back room, get past the broken door with Talia’s Ninja Dash. You can use the lever on the other side to open the faulty door.

On the other side, use the ventilator’s updraft to reach the top of the building to find the puzzle piece. Destroy the padlock behind the puzzle piece and take the slide to find a blue stud at the end.

Return to the tunnel of love and return the pieces. Like in Mission 2: Infiltration, you have to use the Control Wheels to form the League of Shadows’ insignia on the wall. Enter the Tunnel of Love and board the swan to start.

Head to the North Island GCPD building to continue.

This will enter the Point of No Return. You can’t return to the world map until Mission 16: The League of Shadows Returns is finished.

After the fight against the prisoners, Killer Moth and Grundy escape the prison room to find Scarecrow. With Batman and Talia influenced by the fear gas, the team faces more fighting against Bane’s thugs. But also against Ra’s Al Ghul. As soon as the effects of the fear gas wear off, the team can escape, starting Chapter 6.

Chapter 6 officially begins Mission 16: The League of Shadows Returns. This mission is played with Batgirl and Nightwing.

The tunnel ahead is completely blocked. Destroy everything and build a ram on tracks. There is a vent you can destroy with a Hackarang to the left, so Nightwing can connect the ram train to the wall where the vent was. This will charge up the train and blast through the blockage. There is a purple stud down in the sewers to the right after the blockage.

On the left side, still in the safe zone, there is a plug for Nightwing’s staff to charge the dumpster truck. Charge it up by hitting the right button, then switch to Batgirl to use the Hackarang on the dumpster truck. It will drive right in front of the tumbler, and you can go get the Red Brick.

Throughout the years, as I indulged in more and more games, I consistently sought clear guides to swiftly navigate my gameplay. Now, it’s my turn to contribute back to the community.
