Batman Arkham Asylum Walkthrough and Mega Guide

The walkthrough for the Caves will begin with you in the Batcave. Don’t worry, there isn’t anything in the actual Batcave, but we need to get to the southeast corner of the Batcave and grapple up. Once you reach back to the surface, Batman will be facing the small islands to glide down to. You might remember that this is the route you took to the sewers when you got your Ultra Batclaw.

Riddler Trophy
The first trophy can’t be missed. Make your glide down to the first island, and look on the lower levels of that island. It’s right there.

Riddler Trophy
This one will be a little more difficult to spot. After you jumped to the above island, you’d have to Line Launcher across to continue. Stay right there. To the northeast of your position is another island. The trophy is on here. To reach it, make a big jump towards it, but veer off to the left. You should be able to land on a lower part of the island you jumped from. From there look above on your own island to find a grapple target. Grapple up here and jump down to that Island to grab the trophy.

Now, it’s time to Line Launcher across to the island you jumped from, and | | proceed as you normally would to the Old Sewer.

Chronicle of Arkham
As soon as you drop down from the vent, look to your right. There’s a Chronicle in plain view on the western wall here. You really can’t miss this one.

Riddler Trophy
From the Chronicle, look up at the ceiling, towards the north. Do it in Detective Mode and you should see a destructible square up there. Pull it down with your Ultra Batclaw and secure the trophy.

Riddler Trophy
The sewer stream in this room runs to the south. Look in this direction to see a huge circle. Use your Line Launcher to get over there and collect this.

Interview Tape
As soon as you enter through the door, you should see a dead body lying ahead. The Interview Tape is beside his body.

Riddler Trophy
You should see a vent door above the dead body next to the Interview Tape. Pull it down with your Ultra Batclaw and grapple up to secure the trophy.

Joker Teeth
If you follow the hallway to the north and the Main Sewer Junction, you’ll see the three Joker Teeth on the ground. You probably secured these already.

Riddler Trophy
In Detective Mode, you should notice a destructible wall to Batman’s left, or in the west close to the Joker Teeth in the hallway here. It’s at about the middle portion of the hallway. Blow this up and secure the trophy inside.

Instead of continuing north to the Main Sewer Junction, turn around and | | head south to Croc’s Lair.

+—-C r o c ‘ s  L a i r—–+

Joker Teeth
If you didn’t get these three, you’ll see them immediately upon entering the lair close to the door in the west end here.

Riddler Trophy
From the above Joker Teeth, or immediately after entering Croc’s Lair through the door on the west end, look to the ceiling above in Detective Mode for another destructible square. Pull it down with the Ultra Batclaw and grapple up to secure the trophy.

Interview Tape
With the above secured, use your Line Launcher and work your way to the eastern end of the tunnel, where the Intensive Entrance is. Head on into the entrance and it should take you to Control Room Access. Look for the Interview Tape on a wooden crate to your right. You probably got this one already. Head back into Croc’s Lair with this secured.

Riddler Trophy
Once back into the sewer, head to the east, until you are basically at the eastern end of the tunnel. You should see three large cylinders’ that create three mini waterfalls. Look towards the two cylinders on the southern wall and you should see the trophy to the right of one. You’ll need the Line Launcher to reach it, of course.

With the above three secured, make your way back to the western end and | | through the door to the Old Sewer. Head north down the long hallway now | | to the Main Sewer Junction.

+—-M a i n  S e w e r  J u n c t i o n—-+

Riddler Trophy
Once inside, immediately sprint north until you hit a railing. Look to the northwest now and you should see the end of a broken catwalk. Don’t know what I’m talking about? Note the thin waterfall between the two catwalks directly north. Our target is the catwalk to the left of that tiny waterfall. Take out your Line Launcher and latch onto the nearby pillar. You should see the Riddler Trophy around the corner here.

Riddler Trophy
With the above secured, jump to the east to the other end of the broken catwalk and continue as if you were making your way up this cavern the first time. Immediately after jumping from the catwalk to a lone platform (it would be the first time that you weren’t on a catwalk in this cavern), look to Batman’s left for grip for Batman to shimmy across. Shimmy to your left and climb up when you see the opening to secure this Riddler Trophy.

Joker Teeth
After securing the above trophy, jump across the platform to the north and there will be three Joker Teeth here if you didn’t get them the first time around.

Riddler Trophy
This is another one of those that you most likely secured the first time around. Shortly after climbing up the first collapsed pillar that leads you upwards, the path will take you onto a stream in the middle of the room. In the south here is a Riddler Trophy that you’ll be able to jump to. Go directly to the bottom Riddler Trophy.

Riddler Trophy
While standing where you just got your Riddler Trophy, look to the east, across one of Ivy’s big vines. You should see an alcove here with a Riddler Trophy (go into first person mode and look across if you can’t see it). Use your Line Launcher to reach it.

Riddler Trophy
After securing the above two Riddler Trophies, continue up the second collapsed pillar that leads you upwards. This should take you to directly to the second final platform of the cavern if you were to make your exit to Arkham North. While standing on this platform, look to the north and take note of the shimmy grip here. Grab on and shimmy to Batman’s right. It will lead you right to the Riddler Trophy. Go directly to the below riddle.

Riddle
“A puzzle has many sides, but only some are visible.”

After grabbing the Riddler Trophy, climb up the ledge here and go into Detective Mode. Look slightly above, to the west, and you should see another question mark alignment puzzle. Keep Batman as close to the wall to the left as possible to get him out of the way. Stand him there and position the camera to align the question mark and scan.

Joker Teeth
Continue and make the jump to the final platform that will lead you down a hallway to Arkham North. Go straight down this hallway and you should see some Joker Teeth here if you didn’t clean them out the first time around. With this secured, continue on through the door to Surface Access.

Interview Tape
We’re only going to be in Surface Access for a brief visit. Immediately upon entering, turn to the left to see two wooden crates. You’ll find an Interview Tape on one of them. Secure this and head back through the door to Main Sewer Junction.

Riddler Trophy
You should see this Riddler Trophy if you are staring west while standing on the platform leading to the hallway of Surface Access. Go into Detective Mode if you don’t see it. It’s literally right across from you. Use the Line Launcher to reach it.

Riddler Trophy
This is another one you probably got. From the above Riddler Trophy, head north until you can climb up a ledge. Climb up all ledges and sprint in a straight line to the south. Once you can’t go any more, look to the northeast corner of the room and you should see two metal crates (they look like crates anyway). Line Launcher your way here to grab the trophy.

With all of these in your collection, it’s time to head northwest and to | | Joker’s fortress.

Secrets Map
Immediately upon entering the Pump Control Room, look to the right and you’ll find the map on a little stool.

Interview Tape
After grabbing the Secrets Map, head north down to hallway. As you do, keep your eyes peeled for an Interview Tape on some barrels to your right. You might have missed this if you sped through the hallway.

+—-P r e s s u r e  C o n t r o l  J u n c t i o n—-+

Chronicle of Arkham
After entering the junction, head straight ahead to the north, and to the rubble on the bottom of the elevator shaft. Go into Detective Mode and look slightly above in the north. You should see a destructible wall. Pull it down and grapple up to the Chronicle.

Joker Teeth x 9
You will find sets of three Joker Teeth in the hallway leading to the Pump Room (in the west). There is also a little present outside of the Pump Room that give three more Joker Teeth. Finally, in the hallway leading to the Control Room (in the east), there are three more Joker Teeth, making for nine total.

Riddler Trophy
Go into Detective Mode while in the hallway right outside of the Pump Room. While facing the north, you should see a destructible wall. Pull it down and grab the trophy.

+—-P u m p  R o o m—-+

Interview Tape
Immediately upon entering the room, look to the corner in the west to see two barrels. Line Launcher across and pick up the Interview Tape over here.

+—-C o n t r o l  R o o m—-+

Chronicle of Arkham
As soon as you come in, go into Detective Mode and head deeper into the room. Take note of the vent door in the northeast on the lower portion of the wall, but don’t go in. Instead, turn to the south, still in Detective Mode, and take note of the destructible wall. Pull it down and head inside to scan.

Riddler Trophy
Head back to that vent door you didn’t go into. Now, look to the west in Detective Mode and you should see a gargoyle statue. Below that is a destructible wall. Pull this down and climb in for a Riddler Trophy.
