Chapter 11: Underground Retreat

Chapter 11: Underground Retreat

To reach the crashed robot, you can use the activated bat terminals near that location. If not, you have to use a speedboat and disembark on one of the docks in the west and south part of the third island, since all bridges leading here are blocked.

Once inside the metro, destroy the enemies and have Superman pull the orange machine to the left of the electric switch. Assemble the lego pieces in the middle to change into Batman's Electricity Suit then drain the charge from the eletric switch. Pull the handle bar in the middle to remove the debris.

Continue ahead and put out the fire with Superman's Ice Breath. Move forth and assemble the pieces to the right to get the Power Suit. Destroy the silver part to the left. Switch back to the Electricity Suit then power up the generator to the left.

Once the Joker Robot removes its feet,  destroy the large pile of silver pieces ahead and clear the path of the train cars until you reach the next checkpoint.

In the next area, destroy the silver boxes then assemble the parts to fix the nearby machine. Activate the lever and it will spew out new set of parts. Assemble them to change into Batman's Bat Suit. Next, head to the right and destroy the glass pipes. You have to freeze the water afterward then climb up.

Climb up the ice wall as Batman then glide to the next platform. Activate the lever there to stop the train and to remove the cover of the gold part to the left. Destroy the glass cover on the ladder to go down normally. Destroy the golden part and pull the train using the orange handle.

Continue ahead the rail track and turn to the left. Put out the fire then climb upstairs. Glide to the middle platform then glide again to the right. Destroy the glass cover of the ladder then regroup with Superman. Peek through the green wall and arrange the conduits to power it off completely. Pull the path open to reach the upper floor.

Once there, you have to destroy the golden part in the Joker Robot's hand. Otherwise, it will just keep calling for reinforcements. Enter the traincar to head to the next checkpoint.

Hammerfist!

Continue heading to the right and destroy all enemies along the way. Once you've reached an electrified car, destroy the nearby boxes to assemble Batman's Electricity Suit. Drain the power then have Superman pull the orange handle. Continue to the right and change the power switch to complete the mission.
