Early on in Batman: Arkham Knight, the Riddler will reveal himself to be in the middle of a dastardly endeavor (as he is in every Batman Arkham game). This time, the Riddler has taken Catwoman hostage and he would like for Batman to come play a game in order to free her.
Upon arrival, it is discovered that she has been fitted with an explosive collar, one that will need to be unlocked by finding a series of keys to count down her 9 lives (Riddler is so clever). Of course, in order to obtain these keys you will have to complete a serious of difficult challenges: both with Catwoman, and alone.
Out of these missions and challenges, four of them are rooms that will open up after meeting certain requirements within Riddler’s Most Wanted questline. The last of these rooms is called Final Exam, a room that really sets out to kill you.
Luckily this room is far from the most difficult once you know what to do, and it will finally get that damn collar off of Catwoman’s neck so let’s get to it. One thing to note is that you cannot enter the room until you’ve obtained the Remote Electrical Charge which you’ll have to obtain in a later part of the main story. Once you have that you’re ready to rock.
When you head through the doors you’ll find a large room below the platform you’re on. In that large room are a bunch of Riddler floor switches surrounded generators.
On either side of the room are saw-blades ready to rend any unsuspecting superheroes into mincemeat. Upon trying to descend into the aforementioned area, you will be greeted by a giant wall of iron spikes.
What you will need to do is have Catwoman jump up to the ceiling so she can drop down into the room with the switches. Once she’s situated it is time to solve this puzzle.
In the room you will notice that there are empty spaces among the Riddler floor switches. You may have also noticed the beam of light coming from the ceiling.
Your mission is to shift the rows and columns of floor switches so that the beam of light goes into an empty space. How are you supposed to move these blocks without all of them moving together? That’s where Catwoman comes in.
Have her stand on a Riddler Switch to have all the blocks behind her in that row or column (behind is relative to the direction you’re trying to move them) lock in. Shift the remaining blocks over as needed until the empty space is directly under the light.
Once you accomplish this quickly switch over to Catwoman. The saw-blades on the side of the room will trigger. Just look for the gap and crouch there. They will go back and forth a few times before resting.
Now you’ll just have to repeat the same process as before. Have Catwoman block switches, and shift them using Batman’s Remote Electrical Charge.
Then prepare to dodge the blades again. For the third round you will have to clear spaces for two lights instead of one, but it is no more challenging than the first round.
The only major difference is that the saws after the third round of lights never ends. You have to make your way back to the upper level.
The Riddler will be upset, but he is a man of his word (or so he says), so you can collect the final key and watch as relief washes over Catwoman’s face.
Head towards the exit of the orphanage to call it day. Oh wait, we should probably mention that when you try to exit a huge, electrified mech manned by none other than the Riddler himself is out to kill both you and Catwoman along with a small army of color-coded Riddler bots.
Take them out as you normally would, but steer clear of the huge mech and its beam attacks.
Also take note that the Riddler can change the bots’ affinity with a shot from his mech, so don’t rush in, and always be prepared to switch characters. Once they’re all gone Riddler will seal himself in a safe embedded into the ground.
He tasks Batman with completing all of his challenges (riddles, trophies, breakable objects) in order to earn a fight against him.
Catwoman is now safe, but you have your work cut out for you if you hope to put this maniac behind bars for good.
