Batman Arkham Asylum Walkthrough and Mega Guide

The walkthrough begins as you enter the sector from Arkham East.

Joker Teeth x 5
You should see a big set of Joker Teeth as soon as you come in, if you haven’t gotten them already.

***Secrets Map***
Go into Detective Mode and identify the cabin to your right. Grapple to its roof and plant the explosive gel to get in there. You’ll find it on the table

Riddler Trophy
From the cabin where you found the Secrets Map, head west, towards the identical cabin. Go into Detective Mode and you should see a detonable square on the ground between the two cabins. Blow it up and find the trophy in there.

Riddle
“Let’s face it, there are two Dents on the wall.”

Continue to the cabin you identified when you went for the above trophy. Jam the security control panel and go inside. Immediately, look to Batman’s top right to find a couple of lockers. Scan the Harvey Dent posters to the left of those to solve the riddle.

Interview Tape
There is also an Interview Tape on the table here.

Riddler Trophy
Leave the cabin you were just in and head towards the south, the Intensive Treatment Building. Grapple up the building as you stand close to the Arkham West door. Once up there, sprint in a straight line east to find it on the ground.

Interview Tape & Riddler Trophy
Drop back onto the ground and go north to the closest watchtower (the one closest to the Arkham West door). Inside, you’ll find an Interview Tape. There’s a Riddler Trophy on the roof.

Joker Teeth
You should see some Joker Teeth on the watchtower here.

Riddler Trophy
There are also two more in front of the entrance to Intensive Treatment. You should see them from the tower you are on. If you didn’t get them already, line launcher over there.

Riddler Trophy x 2
If you’re on the roof of the watchtower, don’t be. We need you to drop back down under the roof where the Interview Tape is. Go into Detective Mode and look to the west. You should see two Riddler Trophies here. The one on the top can be reached by using the Line Launcher. To get the one below that, drop back down on the ground and use your Ultra Batclaw to pull down the weak wall.

Riddler Trophy
Now time to make your way to the watchtower close to Arkham East. There isn’t anything of particular interest in there, but you will need to use the watchtower roof to jump over to a trophy. Let’s do that, shall we? Get onto the roof and look north. You should see it now. Glide down onto the platform and pick up the trophy.

Riddle
“Tweedledum and Tweedledee SAW it, can you SEE it?”

From the above platform, go even further north and towards the Arkham Asylum gate. To the right of the gate is a see saw set (like the one you would see on a playground). Get right up to it and scan to solve this riddle.

Riddler Trophy
From the Arkham Asylum gate, look east and grapple up to the railing. You’ll need a ranged Cryptographic Sequencer to open this gate. Once you do, grab the trophy sitting inside.

Riddle
“Now I see it, now you don’t!”

Drop down and head south. Keep your eyes peeled to the right for a stone arc leading to a very broken down building. Go into Detective Mode and approach the stone arc, while looking up. Do it slowly and keep an eye out for the top hook of a question mark. You should see it soon. You should also see the bottom circle you have to line it up with. Position yourself and take a scan to solve this.

Chronicle of Arkham
Step back from the stone arc, and move to the right of it. Look up to find a grapple target to a little room here. You’ll find the Chronicle sitting in plain sight.

Riddler Trophy
With the above Chronicle secured, turn to the left of the stone, or to the west and drop down below. You should see the Riddler Trophy in a corner, by the window.

For the last few, head to the southeast portion of Arkham North to the | | Batcave entrance.

Riddler Trophy
Make your way to the opening on the ground leading to the Batcave if you haven’t already. Take a few big strides back and look up. You should see a target to grapple up. The Riddler Trophy is sitting here in plain sight. You should see another one behind some bars. Don’t worry, we’ll get to it soon.

Chronicle of Arkham
Drop down from the area you are standing on now. Head through the opening and towards the Batcave. Grapple up the first opportunity you see and you’ll find a Chronicle to your left. You probably got this already.

Riddler Trophy
From the above Chronicle, continue deeper into this passage as if you were going to the Batcave. Once you reach the door, turn around and look behind you. Jump to this alcove here to grab the trophy you saw earlier.

Riddler Trophy
Go into Detective Mode and head through the door. Keep your eyes peeled to the right of the screen. You’ll find a detonable wall here. It’s in the room with a bunch of skulls in the centre, and the final room before Batman climbs up and makes the big glide to the cave.
