Go through the green door that has been unlocked after the previous trial.
After you reach a new location, switch to Catwoman and catch on to the grates under the ceiling.

The plan is that you move over a board with interactive pressure plates.
Note- Always remember to pick the appropriate punch in of the electromagnetic pulse.
At the beginning, the free fields are in slots1and25.
Switch quickly to Catwoman and pull her up to the interactive ceiling, becauseRiddlersoon activates spinning blades.
Wait for the cycle of the blades to end, after which they stop.
The second one is much more complicated, because you oughta free two spots for red beams.
The slots in question are5and12.
The slots in question are21and23.
Now, you only need to grab on to the ceiling, as Catwoman (faster than before).
Do not wait for the blades to end their cycle and join Batman.

In here, there is a capsule with the lastkey.
Thanks to obtaining it, you remove the collar from the neck of the Catwoman.
Return to the main hall and give a shot to leave the orphanage.
This will result inRiddlerappearing, in the flesh.
He will be using the machine of his own design and you start your fight with him.
After the fight starts, ignore the boss and attackRiddler’s henchmen.
