Chapter 2: Harbouring a Criminal
Head to the lower right and defeat the two thugs ganging up on a civilian. You can also find four billboards here you can destroy. Assemble the broken pieces near the helicopter to fix the canopy.
Use your batarang to destroy the flashing pieces on the sides of the blue trailer. Destroy the machine inside and re-assemble it to unlock the Power Suit. Change into this suit and destroy the shiny silver pieces nearby.
Destroy the silver spotlight and re-assemble it to unlock Robin's Magnet Suit. Destroy the other spotlight and reassemble it to become a silver cart. Follow the grail of gold studs until a mini-kit appears. Grab it.
Next, have Robin pull the two blue pipes out of the way, then reassemble the broken pieces to create the last blue billboard. Destroy it to get another minikit. Go to the left again and destroy the silver pipes this time to reveal yet another minikit.
Climb up the blue pipes and grapple hook in the middle. Jump to the upper ledge and pull the blue metallic fans so you have something to walk on.
Continue to the right side and defeat the goons. Pull the blue mechanism then switch to Batman. This should break down the lego pieces below which you can reassemble to fix the helicopter's engine.
Next, ride the lift then use Batman's Power Suit to break the metal door open. Pull the ladder down using the Magnet Suit then climb up. Bomb the silver piece ahead then pull it again using the Magnet Suit. Pull the blue piece again, then grab unto the grappling handle.
Destroy the blocks at the end of the ledge then reassemble it to become a zipline. Use the grappling handle to reach the rooftops then continue to the right to find another blue piece. Pull it then use the grappling handle to reach the other side. Defeat the goon there then use Batman to pull the stuck lego pieces. They should fall to the ground. Reassemble the last pieces to fix the helicopter's broken rotor blades. Ride it to continue with the story.
In this next phase, you'll have to chase Joker in his speed boat. You have to use your Batwing's projectiles to completely drain his life bar. His minions will appear from time to time so when they do, destroy them all first before focusing your fire again on the joker. You have to repeat this 4 times until all his hearts are gone.
Chasing the Joker
After the scene and checkpoint, you'll have to fight him again on the ground. There are two minikits you can get here. First, destroy all the cars in the parking lot then for the other, simply ride the bumpcar in the lower lefthand corner.
To take out the Joker's first heart, push the green paddle to aim the cannon towards him then use Batman's power suit to pull the trigger.
For the second phase, assemble the pieces near the clown face to the upper right corner of the parking lot. Blast its teeth then assemble the blue pieces so Robin can walk on it. Reach the top then destroy the gray cover. Pull the rods out so the swinging signs to take out the Joker's second heart.
For the final phase, destroy the large vehicle where his goons came from then dis-assemble it by alternately blasting the silver parts and pulling the blue parts. Once completely destroyed, reassemble the pieces to become a giant hammer then use Batman to pull it and defeat the Joker.

After destroying the statues, the gate will open. Follow the transparent blue studs to reach your objective. Once you reached the terminal with the bat logo, activate it to reach the batcave. Once inside, use the lift to continue with the story.
After the scene, you'll be controlling Bruce Wayne. Head to the right and activate the terminal there. Activate the terminal then select the location with the bat logo. Place a beacon there to proceed with the story.
Drive to the Arkham Asylum then activate the terminal. Drive to the entrance to proceed. You'll be inside the maze.
