Lego Batman 2: DC Superheroes Walkthrough Part 6 – Harbouring a Criminal

The Joker
After a good cutscene, Batman hops into his jet and it is off in pursuit of capturing the Joker. Batman first needs to focus on taking out the Joker. While he has 4 hearts, this is a little more complex than just shoot him down. Once the first heart is gone the Joker will be invulnerable. He will also summon 4 goons on Jet skis with rockets to attack the Caped Crusader. Once there are in pursuit, you need to shoot them down. They all have individual life bars to make it a little more annoying.

With the first wave down, Batman can once again attack the Joker. Drain down his second life bar to get another heart. This will get the Joker to call in 3 Helicopters to attack Batman. They fly in a slow circle launching missiles at the jet.

With them down, it is onto the third heart against the Joker. Destroy the grenades he launches at you and drain the lifebar. He will go invulnerable again and call out another trio of henchmen. Again, they come in Jet Skis, launching grenades at you. They are followed by a trio of Helicopters, in the slow circle again, launching more missiles at you.

Time for the second part of the battle. The Joker will stand on the wreckage of his boat and launch missiles at you. Batman needs to head over to the left, use his Power Suit to destroy the Silver block on the bulldozer and assemble the pieces that fall from its trough. This creates a cannon with a spinner. Push on the green side of it until it stops. It will be lined up for a nice shot at the Joker. Get behind the cannon and tap the prompted button until it fires.

A cutscene will run and then Joker destroys the cannon Batman just built. Now the Joker will launching missiles and throwing pies that give out a radial electric blast. Head for the back center of the area to assemble a ramp onto the bed of a pick up. It will come in handy later. Now head for the Front right part of the battle area. There you will find a pile of pieces you can assemble into a Clown Face. It will give you a lot off chips. Now use Batman's Bombs to blast the teeth of the clown off. Next, assemble those to complete the pathway that is on the right-hand side of the carnival entrance so Robin can climb up. At the top, have Robin get to the center and use the magnet to pull out the 2 pins in the swinging carnival sign. It will come crashing down  onto Joker.

Time for the final part of the fight. He calls in a number of henchmen in a tricked out bumper car. Defeat them then destroy the turret on the front of the car. That will let Robin use his magnets on it. That will cause the blue covering to be removed, showing the shiny silver engine underneath. Have Batman blast it with his bombs to destroy the vehicle.

It will shatter into pieces which you will be able to build into a large hammer. Take out the henchmen that swarm you, build the hammer then use Batman to bring it down on the Joker.
