Enter the Arkham Mansion through the main doors. Our Walkthrough will begin there.
+—-M a n s i o n E n t r a n c e H a l l—-+
Riddler Trophy
As you come in, take a right past the plant growing at the entrance and look for a vent door to the east of the stairs. It’s right on the ground here, no need to go up any stairs.
Chronicle of Arkham
You probably got this one already. Head north up all of the stairs now and you will be in front of a huge door leading to reception. Instead of going in, look above and grapple up to the vents. Once up here, look up again and grapple into the little square. inside is the chronicle. Scan and head through the vent in the north to the main hall.
+—-M a i n H a l l—-+
Riddle
“Who is the main man in the main hall?”
Drop down to the ground floor and turn to the east when you are able to. It should lead you to the south corridor doors. Instead of going in though look to the north wall for a gold plaque of Commissioner Gordon above and between two large display cases. Scan the plaque to solve.
Riddler Trophy
With that secured, head to the northern end of the room and look for the huge statue of Quincy Sharp (bet you thought this was the riddle solution). Look for a vent door on the base of the statue and pull it down with Ultra Batclaw. Climb through for trophy.
Joker Teeth
Head up the stairs along the west wall and even further north now. You should find three joker teeth outside of a vent door leading to an isolated room.
Interview Tape
From the above Joker Teeth, climb through the vent door and pick up the interview tape on the table.
Chronicle of Arkham
Time to head all the way north in the main hall, until you hit a wall/see a bunch of huge windows. Turn around and face the south now, and look up. You should see a grapple target up to the balcony above. If you’re not getting a target, try to move south away from the rubble a little bit and try again.
+—-E a s t W i n g C o r r i d o r—-+
Joker Teeth
There was a purple gift left for you after leaving the Warden’s office the first time. If you didn’t take them out, they’ll still be here.
Riddle
“A game of Cat and mouse can be painful.”
Shortly after coming in, keep an eye out to the east, or Batman’s right for a display case. Inside are a pair of feminine looking glasses, and two gloves with very long nails. Scan this display case to solve
Riddler Trophy
Go into detective mode now and head north towards the door leading to the warden’s office. As you do though keep your eyes peeled to the west, or Batman’s left, for a destructible wall near the middle of the hallway. Pull it down and pick up the Riddler Trophy in there and continue into the Warden’s Office.
+—-W a r d e n ‘ s O f f i c e—-+
Joker Teeth (ie the Joker Teeth that you missed)
Here’s without the doubt the most difficult teeth in the game. Finding it darn near drove me crazy. There are three total. As soon as you come in, look up and grapple up to the balcony. Make a lap around this little records portion of the Warden’s Office to find the teeth.
Riddler Trophy
With those elusive dentures secured, drop back to the ground level and sprint to the north end of this room. You’ll see a few more file cabinets, like the ones you found in the upper floor. You’ll find a Riddler Trophy next to the television set on the table. This one’s easy to miss if you’re speeding through.
Secrets Map
Head into the large room with the painting of Quincy Sharp now (gee I wonder if this guy has enough paintings and statues of himself). Head up the small stairs and make a right to the southern wall here. You’ll find the Secrets Map next to some digital equipment and a stack of papers. Go directly to the below riddle.
Riddle
“Isn’t the Warden too old for a puppet show?”
Literally to the right of the table where you got the Secrets Map is a display case with a… you guessed it, a puppet inside. Scan the puppet to solve this riddle.
Solve the above riddle and head back to the Main Hall. Once there, sprint | | into the West Wing Corridor through the door in front.
Interview Tape
Sprint deeper into the room here and further west. Go into Detective Mode and when you head up a set of stairs, look to Batman’s left, or the south to find a destructible wall. Pull that down and grab the tape inside.
Joker Teeth
There should also be three Joker Teeth on the floor where you stopped.
+—-A r k h a m R e c o r d s R o o m—-+
Riddle
“Our records show that a Strange transfer request was made in this room.”
Inside the records room, sprint straight ahead to the west, and don’t stop until you see a set of stairs to Batman’s left that lead upwards. You should see a room blocked off by a Security Gate here. Jam the nearby Security Control Panel and use your Line Launcher to safely cross the electrified floor. Inside, turn to Batman’s right and scan the file cabinets jammed with too many papers to solve.
Interview Tape
Standing outside of the room with the electrified hallway, look to the eastern wall and you should see a vent door here. It’s beside a bunch of file cabinets stacked very high. Do your thing with the vent and drop down to the desk on the ground floor to collect this.
Riddler Trophy
Head to the west end of the records room and look on the southern wall. You should see a vent door here. Pull it down and head on through. Drop down to the desk on the ground floor and collect the Riddler Trophy.
Secure these and head to the north end of the room to find a door to the north corridor.
Riddle
“Did Amadeus go mad, or was he just dizzy?”
Inside, look for the stairs to Batman’s right and advance in this direction. Once your each the door, you’ll know that it’s locked so don’t bother trying. Instead, head into the nearby vent. Drop into the cell shortly. Now, head to the cell beside yours in the south. Stand at the cell’s entrance and scan the cell’s contents while facing the south to solve.
Joker Teeth
There are also some Joker Teeth in here, but you probably got them already.
Riddler Trophy
From the previous riddle, look to the west now and grapple up the vent. You’ll find yourself standing on a mesh material. You can see the cells below. Don’t waste anytime and head to the southwest corner of this room to find a little alcove and trophy. In other words, from the air vent, sprint straight until you hit the wall. Then, turn right to find the Riddler Trophy.
Continue into Dr. Young’s Office now.
+—-D r . Y o u n g ‘ s O f f i c e—-+
Riddle
“It’ll be a cold day in Hell when this Ghul rises again.”
Head up the stairs to your right and look to where she keeps all of the dead people. You should notice that one of the “fridge doors” are open, and there’s a body bag sticking out. Go into first person mode and scan the foot on the body bag to solve.
Riddle
“How do you mask your feelings without losing control?”
From the above riddle, look to the northern wall and grapple up. Navigate the vent and drop down. Next, look to the northeast wall for a skull hanging in a frame. Scan this skull to solve.
Interview Tape
Grapple back up to the vent now and head through. Once out of the vent, sprint straight south and to the door. Before leaving, pick up the Interview Tape on the nearby desk.
With this secured, it’s time to make our way to the only portion of the | | mansion you haven’t explored: the south corridor and library.
+—-S o u t h C o r r i d o r—-+
Riddle
“What does a bird need in the rain?”
Near the initial portions of the corridor, keep your eye on the eastern wall. There’s a cube display case here, and it holds a top hat and several closed umbrellas. Scan this display to solve.
Joker Teeth
There are three Joker Teeth scattered around the display cases as well.
Riddle
“This fiendish puzzle literally appears out of thin air.”
This is another one of those alignment puzzles. From the above Riddle/Joker Teeth, look up and grapple up to the vents. Go into Detective Mode and proceed on the vents to about where the fans are. Look to the west and slightly below to see the hook of the question mark. The dot is on the vents you are standing on so line these up to solve.
Chronicle of Arkham
Still on the vents, turn around and face the eastern wall. Go into Detective Mode and you should see a destructible portion of the wall here. Blow it up and scan the Chronicle.
Riddler Trophy
Drop down now and head towards door leading to the library. Look to the southwest wall to see a vent door. Pull it down and grab the trophy.
Alternatively, you can try going right up to the door leading to the library, and turn around when you get there. Look up and you should see the vent door.
+—-L i b r a r y—-+
Riddler Trophy
Immediately upon entering the library, look right to see the vent door. Pull it down and grab the trophy inside.
Interview Tape
Still on the initial floor, circle around to the north end. You should see a Security Gate with a Security Control Panel. Jam this and collect the tape on the other side.
Riddler Trophy
Grapple up to the absolute highest floor in the library now. Look for a vent door in the southeast. It will lead you right to a Riddler Trophy.
Joker Teeth
With everything secured, jump all the way down to the basement of the library. Head up the stairs now and you’ll see the Joker Teeth as you head up the stairs (it should just be a single flight).

After spending approx 3hrs crawling over every flippin inch of the Mansion last night I have just read the ever so easy answer of how to get into Dr Jones office. Thank you soooooomuch you've saved my sanity (how ironic!)
– yeaaa these were GREAT instructions! Thankss Chaos Demonn!
Nice walk-through. Very nice. But seriously… Chaos Demon? I'm sure your mom didn't name you that? Watched a lot of "Hackers" when you were a kid, eh? Trying have one of those 1337 names? Just put your real name on the damned thing and stop the nonsense.
Sincerely,
CrYsTaL MeTh
Just leave him alone, hes helping, who cares what his name is
I ask that all OCMS staff use their real names for professional reasons. Even I don't know Chaos Demon's real name, and he didn't want to provide it for personal reasons. He's a guest contributor, and I'm happy to publish more from him.
How do I go across large gaps?
