Batman Arkham Asylum Walkthrough and Mega Guide

The walkthrough begins as you head through the Arkham West door in Arkham North.

Riddler Trophy x2
As you proceed towards the Arkham West, stop when you reach the door. Turn around and go into Detective Mode. You should see a vent door to your right, and a weak wall directly ahead. Grapple up to these locations to grab the trophies.

Joker Teeth
There are also Joker Teeth on the ground here, in the hallway between Arkham North and Arkham West.

Riddler Trophy
Once into Arkham West, head down the initial hill here for a bit and stop when you arrive at about the shrubs. Turn around and grapple up onto the ledge above the Arkham North door to grab this one sitting there.

Riddler Trophy
Drop back down to the hill now. Look to Batman’s left, or to the southeast. Approach the edge here and you’ll see a waterfall. Drop down to collect this Riddler Trophy. Go into Detective Mode if you can’t see it from where you’re standing.

Riddler Trophy
Grapple back up to the Arkham North entrance now, and go down the hill. Turn left towards the Arkham East door when you reach the fork. Follow the path all the way to the Arkham East door, but don’t go in. Instead, go into Detective Mode and look up. You should see a square that you can break down with the Batclaw. Get up there to find the trophy.

Riddle
“Does Scarecrow’s gas break down barriers as it drives you insane?”

Standing at the Arkham East door, turn around and face the entire Arkham West. Look up, and you should see two white structural frames that you can’t grapple up. Do so, and look to the northeast in Detective Mode. You should see a weak wall here that you can pull down with your Ultra Batclaw. Do a scan of the three barrels on the ground to solve this riddle.

***Secrets Map***
From the Arkham East door, follow the path southwest towards the water. You should pass two dead Arkham guards on the way. Turn right at the second dead guard and you should see a cubicle. Get inside with the sequencer and pick up the map.

Riddler Trophy
Leave the cubicle now and go to Batman’s left to the big “Medical” sign. Go into Detective Mode to spot the Security Gate Control. Jam this one and it will cause the nearby lift to turn on. Find this Riddler Trophy in the space where the lift is when it goes up.

Interview Tape
From the Security Gate Control, turn around and sprint in a straight line along the edge of the water here, to the northwest. Look to the left for a wooden cabin. Collect the tape on the barrels inside.

Riddler Trophy
To get this one, we’ll have to grapple up the wooden cabin where you got the Interview Tape. You’ll find the trophy next to some tires.

Chronicle of Arkham
From the wooden cabin, sprint northwest to the tipped over ambulances. Stand next to the ambulance to Batman’s right, or the one closer to the east. From there, go detective mode and look towards the Penitentiary in the west. You should see a detonable arc. Use your Ultra Batclaw to get up there.

Riddle
“Do you see what I can see? No? Then maybe I am in a stronger position.”

Stand next to the ambulance exactly as if you were attempting to get the above Chronicle. This time though, look up higher and grapple up. You should find yourself in the Penitentiary entrance now. Look up one more time and grapple up. You should see a Security Gated door. You’ll need the ranged sequencer for this one. Before going in though, go into Detective Mode and turn around, looking Medical Facility in the southeast. Look down at the platform outside of the Penitentiary entrance. You should see the hook of a question mark. Position yourself behind the middle banister to find the “dot”. Position the camera to form the question mark now and scan it.

Riddle
“Zsasz is counting on you finding his work.”

After securing the above riddle, head into the room with the Security Gate. Once inside, look to the left to see a table of three dead guards hunched over. Get right up to the table and scan them to solve.

Riddler Trophy
Collect the Riddler Trophy in the same room as the above riddle as well.

Riddler Trophy
Leave the room where you cleared the above two challenges and look out at Arkham West, as if you were trying to solve the “Do you see what I can see” riddle. This time though, look to Batman’s left, or the northeast to identify the watchtower. Make your way over there and collect the Riddler Trophy on the ground, below the tower.

Joker Teeth
There are also three Joker Teeth in the actual watchtower, as well.

Riddler Trophy
Grapple back up to the Penitentiary entrance, and this time make your way to the doors that read “Cell Block”. There should also be a huge plant in front of it. Look to Batman’s right to see a vent door. Pull it down with the Batclaw and collect the trophy inside.

Riddler Trophy
Time to make our way to the Medical Facility entrance. Grapple up once you get there and climb up the first ledge. Turn to Batman’s right, and sprint in this direction, towards the lighthouse. When you reach the very edge of the facility and are one step away from falling into the water, turn to the left to find the Riddler Trophy sitting there.

Riddler Trophy
Still on the Medical Facility roof, turn around and sprint all the way across the roof, to the northeast. Once you reach the edge of this side of the roof, you should have a clear view of the rocky side of this mountain. You should also see the Riddler Trophy in the alcove across. Line Launcher over there to make the pickup.

Riddler Trophy
Head through the Arkham East door now, and look to Batman’s left to see a Riddler Trophy behind bars. Grapple up and blow up the weak portion on the ground to collect it, for the final challenge.

Joker Teeth
There are Joker Teeth in the passage between Arkham West and Arkham East as well.

Joker Teeth
As you make your way to the Medical Facility, there are Joker Teeth in front of the door. Don’t forget about these.
