The eighth 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 newly lit up green door.

Following a brief bit of Riddler monologue, the pressure plate on the floor in here will become active. Step on this with Batman. This will lower a grate near the ceiling. Switch to Catwoman and have her crawl across the ceiling, through the new opening and drop down on the other side. Step on a second pressure plate here to begin the next puzzle.

Both rooms will now receive an electrified floor and we’ll need to make our way across this using a safe path to reach a pressure pad at the far end. This puzzle is quite similar to the first puzzle we undertook at the orphanage as the solution for the other character’s safe passage through the electrified floor will be presented on a large screen at the back of the room with lit up lights indicating a safe route.

Use the roof to get over the fence (left). Well now need to cross a pair of electrified floors (right).

The safe routes are the following:


  • Start at the far left and move forward three tiles.
  • Walk right two tiles.
  • Walk back towards the entrance one tile.
  • Walk across two tiles to the right hand wall.
  • Move up four tiles towards the back wall.
  • Walk two tiles to the left.
  • Go towards the back wall one more tile.
  • Go left one tile.

Catwomans path (left) and Batmans path (right).


  • Start in the centre and move forward two tiles.
  • Walk left two tiles until you hit the wall.
  • Move forwards two tiles.
  • Walk three tiles to the right.
  • Move forwards one tile.
  • Move to the right one tile.
  • Move forwards one tile.
    As soon as both characters have completed their side of the puzzle, the walls will drop down and you’ll be placed into a dual-combat situation against 10 Riddler Robots. Remember that Batman will only be able to attack blue Robots and Catwoman the red ones.

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