Batman: Arkham Asylum Riddler Guide

Our walkthrough to all 240 challenges! Every map, every trophy, every interview, every chronicle and more

(Extreme Incarceration)
After locking away Harley Quinn, simply walk into the control tower she formerly occupied. The map is on a desk on the ground level, right past the main door.

PENITENTIARY - RIDDLE SOLUTIONS VIDEO

PENITENTIARY- RIDDLE SOLUTION #1

(Cells Access)
"How do you reflect on your successes and failures, Batman?"
There's a restroom to the west of the Penitentiary's reception area. Go to the Women's side and scan Batman's reflection in the grimy mirror.

PENITENTIARY- RIDDLE SOLUTION #2

(Main Cell Block)
"Two people, one voice, no gun?"
Ignore all the crazy people in this room - if they haven't already been released - and grapple to the raised area above their cages. Look north and you'll see a catwalk that leads to a separate room. The wall is inscribed with Latin and there is a display case with Ventriloquist's machine gun inside. Scan it to solve the riddle.

PENITENTIARY- RIDDLE SOLUTION #3

(Security Control Room)
"A case of mistaken identity?"
At the back of this room is a holding cell with handprints smeared all over the glass. There's a sign warning that the prisoner within can impersonate other people. He might be Aaron Cash, Warden Sharp or Commissioner Gordon when you see him... but in reality, it's Clayface. Scan him to solve the riddle.

PENITENTIARY- RIDDLE SOLUTION #4

TOOL NEEDED: Cryptographic Sequencer
(Main Cell Block)
"This room is the end of days for even the most celebrated killer."
While chasing Harley and fighting off escaped lunatics, look for a small cell covered in calendar pages. Scan the room for the solution and more info on the villain Calendar Man.

PENITENTIARY- RIDDLE SOLUTION #5

(Controlled Access)
"What has four walls, two sides, and one ex-DA?"
Why, that must be Harvey Dent, aka Two-Face! You can't miss his cell - it's the one with the big "Vote Dent" poster on the wall and the "Vote Dent" button next to the toilet. Scan the poster to solve the riddle.

PENITENTIARY- RIDDLE SOLUTION #6

(Extreme Incarceration)
"All alone in your cell? Why don't you break the ice with the most dangerous prisoners?"

Clearly, this riddle is referring to Mr. Freeze. You'll find his rather large and rather frozen prison cell in the area where you locked up Harley Quinn. Scan the whole thing.

PENITENTIARY- RIDDLE SOLUTION #7

TOOL NEEDED: Ultra Batclaw
(Guard Room)
"Prometheus, Arkham guards' most wanted and most hated."
To gain access to the solution, you'll need to get rid of the green Joker toxin in this room first. Grapple to the vents above the two guards and tear down the destructible wall there. Then, look across the gas-filled room to see another destructible panel - you'll need the Ultra Batclaw for this one. Once that's destroyed, simply throw a Batarang at the control box to clear the toxin. Now you're free to drop down and locate the locker area, which holds a poster of the cop-hating villain Prometheus.

PENITENTIARY- RIDDLE SOLUTION #8

TOOLS NEEDED: Ultra Batclaw, Detective Mode
(Guard Room)
"When is something right in front of you but still hidden from view?"

This is a question mark alignment puzzle. To get the right view, you need to clear the Guard Room of green toxin first. Check the Prometheus Riddle above to see how. Next, go across to the room that held the toxin switch box and look back to the vent area above the guards' control room... where you just were. The symbol should be lined up perfectly.

PENITENTIARY- PATIENT INTERVIEW #1

(Cells Access)
Immediately upon entering the Penitentiary through the front door, you should see this interview tape waiting for you on a desk to the right side.

PENITENTIARY- PATIENT INTERVIEW #2

(Main Cell Block)
This is one of the offices that is accessible by catwalk from the raised area above all the crazy people's cages. It's to the left if you're facing Ventriloquist's gun display case. The tape is on a desk.

PENITENTIARY- PATIENT INTERVIEW #3

(Guard Room)
Rescue the two guards from Harley - the ones hanging above the electrified water - and follow them into the room with the green fogged windows. The interview tape is easy to spot on the cluttered desk in here.

PENITENTIARY- PATIENT INTERVIEW #4

TOOL NEEDED: Batclaw
(Controlled Access)
In this room, you need to pull down a ceiling grate and grapple up to an office in order to turn off the electrified gate below. While up here using your cryptographic sequencer, make sure to pick up the interview tape sitting nearby.

PENITENTIARY- PATIENT INTERVIEW #5

(Extreme Incarceration)
After throwing Harley into the prison cell, head inside the control tower she formerly occupied. At the top level, right outside the area with the numbered security panels, is a desk with the tape.

PENITENTIARY- CHRONICLE #1

TOOLS NEEDED: Cryptographic Sequencer, Explosive Gel
(Extreme Incarceration)
In the room where you lock up Harley, check out cell #5 on the upper right side. Inside is a trophy... and beyond that, an Arkham chronicle. To get inside, you'll need to head back to the main control tower and go upstairs to the numbered security panels. Use your sequencer to hack into panel #5 and the door below will open. Nab the trophy, then destroy the cell's back wall with gel. The chronicle symbol is revealed! To escape afterwards, just grapple up.

PENITENTIARY- CHRONICLE #2

TOOL NEEDED: Ultra Batclaw
(Guard Room)
To gain access to this chronicle, you'll need to get rid of the Joker toxin in the Guard Room first. See the Prometheus Riddle for how to do so. Once the area's cleared, check the southern wall for a destructible panel, and beyond it, the beetle symbol.

PENITENTIARY- CHRONICLE #3

TOOLS NEEDED: Explosive Gel, Line Launcher
(Main Cell Block)
In the short hall that leads from the Main Cell Block to The Green Mile, watch the left wall for a destructible patch. Beyond is a long stretch of electrified water. To get across and scan the chronicle, you'll need the Line Launcher.

PENITENTIARY- RIDDLER TROPHY #1

(Cells Access)
There's a restroom to the west of the Penitentiary's reception area. Go to the Men's side and look for the trophy in the last stall.

PENITENTIARY- RIDDLER TROPHY #2

(Main Cell Block)
In the short hall that leads from the Main Cell Block to The Green Mile, watch the left wall for a destructible patch. Blow it up and you'll find a trophy, as well as a bunch of electrified water.

PENITENTIARY- RIDDLER TROPHY #3

(Security Control Room)
At the back of this room, to the left of Clayface's hand-smeared glass cell, is a metal staircase. Follow it up and explode the small bit of destructible wall you find. A trophy is in the area behind.

PENITENTIARY- RIDDLER TROPHY #4

(The Green Mile)
This is the room that holds - or held - Poison Ivy. In fact, you won't find the trophy until after she and all the other prisoners in the area have been released. Then it's just sitting in one of the cells on the western side.

PENITENTIARY- RIDDLER TROPHY #5

(Main Cell Block)
This is the room with Calendar Man's paper-plastered cell. Along the southern wall of the room is another cell with a trophy sitting on its bed.

PENITENTIARY- RIDDLER TROPHY #6

(Main Cell Block)
As you're walking up the stairs between the western Main Cell Block and the Guard Room section, look up. Through the ceiling pattern, you should spot a trophy. To get it, head into the Guard Room, hang a left and pull down the grate you see high above you on the left wall. Grapple up and follow the air ducts until you arrive in the desired area.

PENITENTIARY- RIDDLER TROPHY #7

(Controlled Access)
When you're walking through this row of cells, you might notice a trophy - behind bars - on the northern side of the room. To get it, you must head upstairs, bomb the destructible walls and drop down into the cell from above.

PENITENTIARY- RIDDLER TROPHY #8

TOOLS NEEDED: Cryptographic Sequencer, Explosive Gel
(Extreme Incarceration)
In the room where you lock up Harley, check out cell #5 on the upper right side. A trophy! To get inside, though, you'll need to head back to the main control tower and go upstairs to the numbered security panels. Use your sequencer to hack into panel #5 and the door below will open. Voila - the trophy is yours! Harley will trap you in here, but one of the walls is destructible. Blast and grapple your way out, nabbing an Amadeus Arkham symbol along the way.

PENITENTIARY- RIDDLER TROPHY #9

TOOL NEEDED: Cryptographic Sequencer
(Security Control Room)
Once you have the sequencer, go back to the room where you found Warden Sharp and the impersonator Clayface. Climb the stairs at the northern end, where there are two cells at the top. One contains a super creepy inmate with one arm; the other contains the trophy. Just hack the panel to get in.

PENITENTIARY- RIDDLER TROPHY #10

TOOL NEEDED: Ultra Batclaw
(Guard Room)
To grab this trophy, you'll need to clear the Guard Room of Joker toxin first. See the Prometheus Riddle above to see how. Once done, simply grapple to the area that held the toxin switch box and walk through the door. The trophy is on the other side, no longer separated from you by an electrified gate.

PENITENTIARY- JOKER%26rsquo;S TEETH #1-3

(Cells Access)
Before leaving the first area of the Penitentiary, you'll come across three sets of teeth in front of the door to the Main Cell Block.

PENITENTIARY- JOKER%26rsquo;S TEETH #4-6

(Main Cell Block)
Grapple to the raised area above all the crazy people's cages. Turn north and cross the catwalk into the room with the Ventriloquist's gun. Turn left and you'll see the teeth chattering around a side office.

PENITENTIARY- JOKER%26rsquo;S TEETH #7-9

(Guard Room)
After rescuing the two guards from Harley - the ones hanging above the electrified water - the teeth will be impossible to miss. They're in front of the door leading back to the Main Cell Block.

PENITENTIARY- JOKER%26rsquo;S TEETH #10-15

(Main Cell Block)
These will be directly in your path as you chase after Harley. The first three are right outside the Calendar Man's paper-covered cell. The next three are near the exit of the Main Cell Block as you enter Controlled Access and the boss fight.

PENITENTIARY- JOKER%26rsquo;S TEETH #16-17

(Extreme Incarceration)
Lock away Harley Quinn, then walk through the door at the bottom of her control tower. Two sets of teeth are right inside.

PENITENTIARY- JOKER%26rsquo;S TEETH #18-20

(Controlled Access)
After locking away Harley, exit Extreme Incarceration and you'll find a purple gift box waiting for you in Controlled Access. Just approach to release the three sets of teeth.
