Batman: Arkham Asylum – Riddler Guide

CAVES

CAVES - SECRETS MAP

TOOL NEEDED: Ultra Batclaw 

(Pump Control Room)
This is the first room you enter while trying to shut down the three Titan pump valves. You'll use the Ultra Batclaw to tear down a wall, revealing a group of thugs. Defeat them, then grab the map off the computer terminal stool.

CAVES - RIDDLE SOLUTION #1

TOOL NEEDED: Detective Mode 

(Main Sewer Junction)
"A puzzle has many sides, but only some are visible."
This is a question mark alignment puzzle. While running up the second collapsed column, you'll see a hand hold on the platform above. Use it to shimmy around, climb up and then look at the brick wall in front of you to spot the symbol. There's a trophy here, too.

VIDEO: CAVES – EVERY RIDDLE SOLUTION

CAVES - PATIENT INTERVIEW #1

(Old Sewer)
Just follow the objective path on your first trip through the sewers and this one will be obvious. It's next to a doctor's corpse, underneath a grate hiding a Riddler Trophy.

CAVES - PATIENT INTERVIEW #2

(Surface Access) 
Immediately after you exit the Main Sewer Junction - the cavernous room with all the crumbling brick columns - you'll find this tape waiting for you on a couple of wooden crates.

CAVES - PATIENT INTERVIEW #3

(Control Room Access) 
When entering the Caves again to find Croc's Lair - from Intensive Treatment - you'll pass through this room first. The interview is waiting on top of a wooden crate.

CAVES - PATIENT INTERVIEW #4

(Pump Control Room)
This is pretty hard to miss, sitting on a metal barrel in the hallway between the Pump Control Room and the Pressure Control Junction.

CAVES - PATIENT INTERVIEW #5

TOOL NEEDED: Line Launcher 

(Pump Room) 
When you enter this room, you're in a high position and the control panels are below you. Rather than drop down, Line Launch to the barb-wired platform across from you. The tape is sitting on a barrel here.

(Having trouble re-entering the pump section later in the game? When you reach the electrified door blocking your entrance into the central hub of the Pressure Control Junciton - with the dead Titan henchman lying in the center of the floor - turn on Detective Mode and follow the orange wires. They'll actually lead you back through the door you just came through... the security panel is on the other side.)

CAVES - CHRONICLE #1

(Old Sewer) 
Drop into the Old Sewer from the Batcave path and turn right. You should see the tablet only a few yards away from you, against the brick wall.

CAVES - CHRONICLE #2

TOOL NEEDED: Ultra Batclaw 

(Pressure Control Junction) 
In order to escape the Caves after shutting down the Titan pumps, you need to Ultra Batclaw a couple of walls down in the elevator shaft. Behind the first one, you'll find a message from Amadeus Arkham.

CAVES - CHRONICLE #3

TOOL NEEDED: Ultra Batclaw 

(Control Room)
As you enter this area, you can turn left or right and see a destructible patch on either of the diagonal walls. The one on the right hides a chronicle tablet. Use the Ultra Batclaw to gain entry.

(Having trouble re-entering the pump section later in the game? We did too! See our solution under Patient Interview #5.)

CAVES - RIDDLER TROPHY #1

TOOL NEEDED: Batclaw 

(Old Sewer) 
Just follow the objective path on your first trip through the sewers and you'll probably spot this one. It's in a high grate, above the doctor's corpse and patient interview.

CAVES - RIDDLER TROPHY #2

TOOL NEEDED: Explosive Gel 

(Old Sewer)
As you're walking from the watery sewer area (Old Sewer) to the cavernous area with the crumbling surfaces (Main Sewer Junction), you'll pass through this hallway. It also holds an interview tape, three sets of teeth and a trophy in a high grate. This second trophy is behind a destructible wall, halfway down the passage.

CAVES - RIDDLER TROPHY #3

(Main Sewer Junction) 
If you're starting at the bottom of this room and moving upward, the trophy is near the beginning of your climb. Just jump onto the first block, make your first small jump and turn left (or west). After a longer jump, you'll turn a corner and find it on the floor.

CAVES - RIDDLER TROPHY #4

(Main Sewer Junction)
After jumping off the ground-level metal catwalks, but before jumping across to the first fallen column (which also holds two sets of chattering teeth), look at the wall next to this middle platform. See the hand holds? Grab those and shimmy left around the corner. Climb up and find the trophy in a reddish alcove.

CAVES - RIDDLER TROPHY #5

(Main Sewer Junction) 
Again, this is almost impossible to miss if you're climbing the room properly. About halfway up, you'll jump into a shallow stream of water, right before walking up the second fallen column. Simply jump across to the red alcove to nab the prize.

CAVES - RIDDLER TROPHY #6

(Main Sewer Junction) 
While running up the second fallen column, you'll see a hand hold on the platform above. Before jumping across to the room's exit, grab that and shimmy right, around the corner. Climb up, climb again and there's the trophy.

CAVES - RIDDLER TROPHY #7

TOOL NEEDED: Line Launcher 

(Croc's Lair)
This is in the long sewer tunnel with fast-running green water. The entrance to Croc's Lair is on the western end of the tunnel. The trophy is on the eastern (dead) end.

CAVES - RIDDLER TROPHY #8

TOOL NEEDED: Ultra Batclaw 

(Croc's Lair) 
Before exiting this tunnel and entering the Old Sewer, take a look at the ceiling with Detective Mode turned on. If you're in the area with the metal door and the barrels, you should see a destructible panel above that you can pull down with the Ultra Batclaw. Afterwards, just grapple up to find a green-hued room and the trophy.

CAVES - RIDDLER TROPHY #9

TOOL NEEDED: Line Launcher 

(Old Sewer) 
You'll have passed this trophy a couple times on your trips through the sewers, but you can't cross the gap and reach the circular cutout in the brick wall until you have the Line Launcher. Then the trophy is a quick zip away.

CAVES - RIDDLER TROPHY #10

TOOL NEEDED: Ultra Batclaw 

(Old Sewer) 
Drop into the Old Sewer from the Batcave path and turn left, then look up at the ceiling. See the destructible panel there? Pull it down with the Ultra Batclaw and grapple into the alcove to find a trophy.

CAVES - RIDDLER TROPHY #11

TOOL NEEDED: Line Launcher 

(Main Sewer Junction) 
After traversing the first fallen column and jumping into the shallow stream of water, jump the next gap and into the little dead-end alcove. Turn left - far away, on the opposite side of the chamber, you should see another alcove with the trophy. Line Launch across the distance, passing some twisted vines along the way.

CAVES - RIDDLER TROPHY #12

TOOL NEEDED: Line Launcher 

(Main Sewer Junction) 
This trophy is directly on your path from the bottom of the chamber to the top, if headed towards the Pump Rooms. It's sitting right in front of one of the brick archways, directly opposite the door to Surface Access and Arkham North exit.

CAVES - RIDDLER TROPHY #13

TOOL NEEDED: Line Launcher 

(Main Sewer Junction)
This trophy is also directly along your path from the bottom of the chamber to the top, if headed towards the Pump Rooms. You'll pass after your second Line Launch across the chamber.

CAVES - RIDDLER TROPHY #14

TOOL NEEDED: Ultra Batclaw 

(Pressure Control Junction) 
This can be found along the passage to the smaller, western Pump Room. As you head there, watch the right wall for a destructible patch. Pull it down with the Ultra Batclaw and grapple up for the trophy.

(Having trouble re-entering the pump section later in the game? We did too. Read our solution under Patient Interview #5.)

CAVES - RIDDLER TROPHY #15

TOOL NEEDED: Ultra Batclaw 

(Control Room) 
As you enter this area, you can turn left or right and see a destructible patch on either of the diagonal walls. The one on the left hides a trophy. Use the Ultra Batclaw to gain entry.

CAVES - RIDDLER TROPHY #16

(The Batcave) 
Grab this one as you're gliding from island to island between the Batcave and Old Sewer. It's on the first island, at the lowest point... the only way you could miss it is if you flew too far and forgot to look down.

CAVES - RIDDLER TROPHY #17

TOOL NEEDED: Line Launcher 

(The Batcave) 
Another trophy hidden in the island outcroppings between the Batcave and Old Sewer. You won't pass this one on the main flight path, however... you have to take a detour by gliding from the second large island to the tiny northern cliff alcove you should see on your map. To get back safely, you'll want to use the Line Launcher.

CAVES - JOKER’S TEETH #1-3

(Old Sewer) 
Just follow the objective path on your first trip through the sewers (after finding the Batcave) and you can't miss these three sets. They're right past the Killer Croc interview tape, and right before the cavernous area with the crumbling surfaces.

CAVES - JOKER’S TEETH #4-5

(Main Sewer Junction) 
While manually scaling this room - the grapple hook doesn't work here - you can't miss these two sets of teeth. They're in a square area right before the first fallen column.

CAVES - JOKER’S TEETH #6-8

(Main Sewer Junction) 
These teeth will be waiting for you at the end of your climb, along the hallway to the metal door exit.

CAVES - JOKER’S TEETH #9-11

(Croc's Lair) 
After defeating Killer Croc, exit his lair through the western end door. You'll pass three sets of teeth on the way out.

CAVES - JOKER’S TEETH #12-14

(Pressure Control Junction)
You'll encounter these three sets on the stairs between the Pressure Control Junction and the western Pump Room.

CAVES - JOKER’S TEETH #15-17

(Pressure Control Junction)
You'll encounter these three sets in the passageway between the Pressure Control Junction and the eastern Pump Room.

CAVES - JOKER’S TEETH #18-20

(Pressure Control Junction)
After shutting down the third and final pump in this area, the Joker will leave you a purple gift box on your way back to the Pressure Control Junction. They contain the final three sets of teeth for the Caves.
