The sixth part of the Most Wanted mission takes place back at Pinkney Orphanage again. Enter the door and move through the area until you are reunited with Catwoman. Head on over and enter the now illuminated green door.

This room features two levels, the lower level has the cabinet with the key and the upper floor has an electricity puzzle. Climb to the upper level to investigate.

On the back wall you’ll see a maze-like web of pipes and three caged areas between sections of the passage with pipes missing. The goal of this puzzle is to guide an electrical charge all the way through the pipes here until it reaches the end.

Hit the button on the wall to start the puzzle (left). Use the pressure plates to move the charge through the tubes on the back wall (right).

There are three pressure plates on the floor here and each of them controls the level of pipes in the caged areas opposite. Depending on how each plate is activated, the pipes will rise to different levels: Catwoman by herself will raise the pipe to the lowest level, Batman will raise it to a medium height and when both characters stand on a pressure plate together the pipe will be elevated to a high orientation.

To start the puzzle, we’ll need to hit the glowing question mark on the left hand wall. To solve the puzzle, you’ll need to perform the following steps as the electrical charge moves through the pipes to get it to its destination:

  • Have Batman step on the left hand pressure plate.
  • Move Catwoman onto the middle pressure plate.
  • Get both Batman and Catwoman to stand on the right hand pressure plate.
  • Leave Catwoman on the right hand pressure plate and have batman move to the central pressure plate.
  • Get both Batman and Catwoman to stand on the left hand pressure plate.
    Once the electricity has reached the end of the tunnels, a short scene will play to end the puzzle. It will also show the lower level of the room suddenly becoming electrified. Fortunately, this is easy enough to deal with – simply jump onto the pressure plate that rises up out of the floor.

Step on the button to make the floor safe (left) and then fight off the Riddler Robots that show up (right).

Drop to the floor and approach the pedestal with the key and you’ll be ambushed by a group of Riddler Robots.

These Robots are slightly different to those that you have fought before in that they will be coloured blue or red rather than green. The colour is very important when fighting these guys from now on – only Batman can safely hit the blue Robots and Catwoman the red. Attempting to attack the other colour will result in an electrical shot similar to punching a guard with a stun stick – not good! You can still hit either colour with a Dual Takedown however, so don’t be afraid to utilise those when they are ready to go.

Following the fight, you’ll be able to approach the nearby pedestal for the sixth key.
