ARKHAM ISLAND, EAST

ARKHAM EAST - SECRETS MAP

TOOL NEEDED: Cryptographic Sequencer 

The Riddler's secrets map is in the ground floor guard room closest to the Arkham Mansion stairs and statue of Warden Sharp. You can't get in, however, until you've received the security-hacking sequencer.

ARKHAM EAST - RIDDLE SOLUTION #1

"The legacy of this island has been well and truly buried."
Head to the cemetery and look for the open, sunken grave. It's well-lit and the headstone is shaped like an "A" for the asylum's founder, Amadeus Arkham. Zoom in and scan the face of the tomb to solve the riddle.

ARKHAM EAST - RIDDLE SOLUTION #2

"Gotham's greatest family towers over the city."
This one's easy enough. Just find Wayne Tower on the horizon, zoom in and scan the giant "W".

ARKHAM EAST - RIDDLE SOLUTION #3

TOOL NEEDED: Detective Mode 

"My challenges appear to those with the correct position in life."
This is a question mark alignment puzzle. Climb to the very top of Arkham Mansion's tallest tower and face south. The dot is on the floor at your feet, but the top half of the symbol is spread out upon the roofs below. Line them up and scan.

ARKHAM EAST - PATIENT INTERVIEW #1

The tape is in the southern guard tower. On a desk. Impossible to miss once you're up there.

ARKHAM EAST - PATIENT INTERVIEW #2

TOOL NEEDED: Cryptographic Sequencer 

The two guard towers here are linked by catwalks. Where those two walks meet, there's an office. Once you can hack your way inside that office with the sequencer, you'll find both an interview and a trophy.

ARKHAM EAST - CHRONICLE #1

Left of the Arkham Mansion stairs is a locked-off courtyard. Grapple over the wall, drop down and check the righthand wall - behind the railway - for a tablet.

ARKHAM EAST - CHRONICLE #2

TOOL NEEDED: Explosive Gel 

Face the Botanical Garden staircase from the graveyard. You should notice a patch of destructible wall on the side of those stairs. Use your gel or your Ultra Batclaw to get inside and find the tablet.

ARKHAM EAST - RIDDLER TROPHY #1

This one's sitting out in plain sight, on a little jetty overlooking Gotham harbor. It's near the southern view of the water, though, not the northern... very close to the Arkham Mansion stairs.

ARKHAM EAST - RIDDLER TROPHY #2

You’ll find this trophy at the very back of the graveyard, near the cliff shore.

ARKHAM EAST - RIDDLER TROPHY #3

Left of the Arkham Mansion stairs is a locked-off courtyard. Grapple over the wall, run to the back and grapple onto the upper balcony. Behind the column here, facing the view of Gotham City, is a Riddler trophy.

ARKHAM EAST - RIDDLER TROPHY #4

This one is above Trophy #2, on a flat section of Arkham Mansion's roof. If you look at your map, you can also see that it's the narrowest part of the roof, separating the northern and southern halves of the mansion.

ARKHAM EAST - RIDDLER TROPHY #5

In the middle of the cemetery is a small wooden shack. The door is open and the trophy is right on the desk.

ARKHAM EAST - RIDDLER TROPHY #6

Grapple and climb your way to the top of the mansion's tallest tower. On the side with the clock face is the trophy.

ARKHAM EAST - RIDDLER TROPHY #7

If you're on the tallest mansion tower, and look down towards the circular tower, you should spot a rectangular recess between the slopes of the roof. A trophy is there - just glide down and grab it.

ARKHAM EAST - RIDDLER TROPHY #8

Located on top of the northwestern guard tower, the one closest to the Arkham North door.

ARKHAM EAST - RIDDLER TROPHY #9

TOOL NEEDED: Explosive Gel

Left of the Arkham Mansion stairs is a flat courtyard. Smack dab in the center of this courtyard is a destructible piece of flooring. Use your explosive gel and take the trophy underneath.

ARKHAM EAST - RIDDLER TROPHY #10

TOOL NEEDED: Cryptographic Sequencer

This one's in the ground floor guard room closest to the Arkham Mansion stairs and statue of Warden Sharp... the same location as the map. You just need to wait until you have the sequencer to gain access.

ARKHAM EAST - RIDDLER TROPHY #11

TOOL NEEDED: Cryptographic Sequencer

The two guard towers here are linked by catwalks. Where those two walks meet, there's an office. Once you can hack your way inside that office with the sequencer, you'll find both the trophy and an interview tape.

ARKHAM EAST - JOKER’S TEETH #1-2

These are halfway up the stairs to Arkham Mansion's main entrance. They don't appear until the story directs you to the mansion, however, and you'll definitely want to get rid of the two snipers on the overhang above first.

ARKHAM EAST - JOKER’S TEETH #3-4

You'll find these two sets as you're making your way to the Botanical Gardens, looking for Harley's fingerprints. They're at the foot of the long stairs. Watch out for lunging lunatics!

ARKHAM EAST - JOKER’S TEETH #5-6

These two sets are in the more southern guard tower of Arkham East.

ARKHAM EAST - JOKER’S TEETH #7-8

These two are on the stairs to the Botanical Gardens. They didn't appear for us until Poison Ivy had turned Arkham's sky red and we were on our way to stop her with the antidote.

ARKHAM EAST - JOKER’S TEETH #9-10

These two are near the door to Arkham West, close to a ground-level guard room. We didn't spot them until after finishing the game, so can't be sure when they first appear.
