Batman: Arkham Knight Riddler guide - how to solve every Riddler challenge

Founders' Island Riddles

"Far away the deflated brute roams, leaving behind what he couldn't ship home."

This riddle can be solved in Port Adams. Look for a cluster of shipping containers on the northwest part of the port, then find one with an open door. Inside are some Santa Prisca crates, one of which you can open with the Batclaw. Do so to find Bane's costume, and scan it.

"An ancient order, lust for power consumed, their patron saint here is entombed."

There's a cemetery in Drescher. Head there and check the west-facing side of the church to see a shrine to Saint Dumas. Scan it to solve.

"He saved the date! All Hallow's Eve! But this calendar killer took his leave."

This one's a little tricky. You'll need to head into the tunnels that run under Lex Corp. Look for a wooden structure that you can grapple into, and you'll find Calendar Man's desk inside. Scan it to solve.

"A million dollar home for a spoilt child, his parents are dead but his parties are wild."

You'll have to scan Wayne Manor to solve this one. To spot it, head for the train station west of Wayne International Plaza. From up here, you can zoom your view across the water to see the mansion.

"This tumbledown ruin's not looking its best, but what do you expect from the Penguin's old nest?"

Cobblepot Manor is found on the southwest side of island, north of Port Adams. Head there and scan the sign above the door to solve this.

"Crusaders of old had a trusty steed. How much horsepower does a Dark Knight need?"

This might be the easiest riddle in the game - just scan the Batmobile.

"This cold corporation changed his life forever, curing his wife now a chronic endeavor."

To solve this one, you need to scan the Goth Corp sign. The building is located in Otisburg; head there and find a vantage point on the nearby tracks to get a good view.

"He lives and dies in seven days, this beast you've tamed but his song still plays."

Check the underground area near Perdition Bridge to find this sheet of metal you can grapple over. On the other side is a door leading to a very small room containing a poster of Solomon Grundy and a record player playing a creepy tune. Scan this setup to solve the riddle.

"Roll up! Roll up! For the circus of strange, this porcine professor is clearly deranged."

You'll have to reach the end of The Perfect Crime side quest for this one, as it will give you access to Pretty Dolls Parlor. When you do, head all the way to back room and look for a circus poster on the wall. Scan this to solve the riddle.

"A psycho killer's grim design, what has an angle but just one line?"

Head to the docks at the northern edge of the island. Move west around the perimeter to find some bodies posed as if fishing. Scan them to solve.

Founders' Island Trophies

Port Adams

Inside a small building by the entrance.

Port Adams

Near the center of the port is a squad of Riddler bots in a cage. Use the Voice Synthesizer to order them across the little bridge onto the green smudge. Once they're all in place, chuck a Batarang at the switch above to crush them all simultaneously with a shipping container. This will free the trophy in the cage where they first were.

Port Adams

On the west side of the port is a stack of crates holding a caged trophy, but to get it, you'll have to return to Miagani Island. There's a pressure pad high atop the Urbarail Station in Bristol, and stepping on it triggers a timer. You'll have to gun it back to Port Adams and grab the trophy before it goes back into its cage when time expires.

Port Adams

There's a Riddler puzzle in the southern portion of the yard. Hop out of the Batmobile and stand at the end of the shipping container tagged with question marks. Use the Batmobile remote controls and the winch to pull out the three metal bars plugged into the container - be aware that they will slowly move back into position. While they're out, switch back to Batman and guide a Remote Controlled Batarang through the holes in the container to hit the switch on the far side. Trophy's yours!

Port Adams

There's a small dock on the eastern edge of the port. Drop down there to find this.

Penitence Bridge

There's a little house with a deck by the water adjacent to Penitence Bridge. Drop down there to find this.

Otisburg

In west Otisburg, you'll find this green panel on a building. Using the Batmobile's Forensics Scanner on it will cause Riddler marks to appear. These will lead to a weak wall on a construction site in Ryker Heights - you'll have to perform a leap over a winch-able ramp to get there - which you can blow through to reveal a trophy.

Otisburg

There's a crumbling building near the edge of the island. Grapple up to it to find a trophy.

Otisburg

On the eastern side of the area is an Urbarail track. Zoom in to spot a cracked portion and shoot it with the Batmobile's cannon. Grapple or glide into the hole to find a trophy inside.

Otisburg

There's a Riddler puzzle right near Penitence Bridge. You need to guide the trophy ball to the prize slot by using the Remote Electrical Charge in conjunction with the Batmobile's winch. The path is pretty straightforward - just remember that differing pulses from the Charge repel or attract the ball.

Otisburg

Just north of Penitence Bridge, you'll find another puzzle on a rooftop. This one's quite simple. You need to command the Riddler bot to bring the trophy to you, so use the Voice Synthesizer to do so. Just be sure to use the Remote Hacking Device to temporarily blind the sentry gun monitoring the path.

Otisburg/Drescher

On the Urbarail track that runs along the border of these two areas is a caged trophy, but to get it, you'll need to head all the way to GCPD. On the south-facing wall is a console you can power up with the Batmobile winch. Doing so frees the trophy and starts a timer. You'll have to rush back to it and quickly grapple up to the track to grab it before time expires. The only way to do this effectively is to gun for the edge of the docks facing the Lady of Gotham, eject, and grapple-launch your way there.

Otisburg/Drescher

There's a courtyard to the west that also serves as a border. Head there and look for a cracked wall high up on a house. Shoot through with the Batmobile's cannon to find a trophy on the other side.

Otisburg/Drescher

In the same courtyard is a shutter with a winch hook. Use the Batmobile to rip it off, then head inside for a simple Riddler puzzle. Step on the pad to reveal the trophy, then grab it with the Batclaw. A cage will then rise around you, so switch to the Batmobile remote controls to pull it out of the way.

Otisburg/Drescher

Head to the damaged roof of the building that held the previous trophy to find this amongst the rubble.

Bank of Gotham

On the roof of the building is a cracked wall. It's tough to spot, but you can zoom in and blast it with the Batmobile's cannon. There's a trophy beyond.

Pretty Dolls Parlor

You'll come here at the end of The Perfect Crime side quest. You can see it inside the main office as soon as you enter. Reach it by slipping through the nearby grate and blowing through the destructible wall with Explosive Gel.

Lex Corp

There's a Riddler puzzle on a balcony midway up the building. There are two pressure pads and a Riddler bot that will attack on sight. Use the Voice Synthesizer to order him onto one pad - make sure he's facing away from you - then step onto the other. Use the Batclaw to snatch the trophy when it pops.

Wayne International Plaza

Check the top floor of the station under construction on the west end of the plaza. You'll find the trophy in a room filled with chairs.

Wayne International Plaza

Hanging out in plain sight on a balcony facing Lex Corp.

Ryker Heights

Drive through the lower passages in central Ryker Heights to find this green panel, and use the Batmobile's Forensics Scanner to reveal Riddler marks on the ground. These will lead you through a manhole to a construction site to the east. The path ends at a weak spot in the wall, so shoot through, exit the vehicle, and climb through the hole to find a trophy on the other side.

Ryker Heights

In central Ryker Heights is a bridge you can tilt back using the Batmobile's winch - it becomes a ramp you'll use during the story. Once it's tilted back, check the space under it to find a trophy.

Ryker Heights

Head to the docks at the northwestern tip of the island. Facing the water is a wood panel. Bust through with Explosive Gel or a glide kick to find a trophy on the other side.

Ryker Heights

Directly above the previous trophy is a Riddler puzzle. Use the Batmobile's winch to lower the panel above, then grapple into the cage. Stepping on the green pad frees the trophy, but stepping on any red pad seals it up again. To safely cross, you'll need to find a good spot to dive bomb and speed-glide your way into the cage and over the red pads to secure the trophy.

Ryker Heights

There's a rundown building in the northeast corner of the island. Check the top floor.

City Vision Construction

Directly south of the docks is a Riddler puzzle inside the large building under construction. Use the Batmobile winch to power up the panel on the wall, revealing a Riddler bot and a pressure pad inside a cage. Use the Voice Synthesizer to have it step onto the pad, releasing the trophy.

City Vision Construction

You'll find this one in the passageways beneath the building, but it's sealed away. To get it, head to the walkway connecting the two circular towers just west of here. Step on the pressure pad here to start a timer, then floor it back to the trophy before it expires.

Trade House

The Trade House sits at the docks at the northern edge of the island. Along the north-facing wall is some wood paneling you can bust through with Explosive Gel or a glide kick. You'll find a trophy on the other side.

Trade House

Atop the lighthouse at the northern tip of the island.

Drescher

Near Perdition Bridge, you'll find a Riddler puzzle embedded in the corner of a building. Use the Batmobile's winch to pull out a panel housing three Riddler switches, then nail these with a triple Batarang to win the trophy.

Drescher

Drive into the lower roads just south of the previous trophy, and look for this ledge by where the road bends. Grapple up there to find the trophy by a trashcan.

Drescher

There's a Riddler puzzle along the lower roads that run by the cemetery. First, use the Voice Synthesizer to place one of the Riddler bots on the pressure pad, opening a nearby shutter. Step through and blow through the cracked wall with Explosive Gel. Then crawl through the vent to reach the squad of Riddler bots; take them out to earn a trophy.

Perdition Bridge

There's a shutter by the water immediately south of the bridge. Hit the generator above it with each mode of the Remote Electrical Charge to open it, revealing a Riddler puzzle inside. There's a sentry gun guarding the trophy, so hit the Riddler switch to block its view with another shutter. When you grab the trophy, a squad of Riddler bots will appear. Guide a Remote Controlled Batarang to the switch to release the sentry gun, which will blow them all away. Send another to ensure your safe exit.

Subway under Divinity Church

This is the subway you enter while the city is overrun with the Cloudburst toxin. The first trophy is inside the control room in the corner of the opening chamber. Drop in through the ceiling.

Subway under Divinity Church

Found just after the first security gate. When you disable the second drone, check the desk nearby.

Subway under Divinity Church

This is atop the control room where you create a ramp for the Batmobile to launch over some water.

Subway under Divinity Church

When you head up the escalator, drive forward to find three splintered wooden doors. Grapple up to the walkway near the center door to find this.

Subway under Divinity Church

Bust through the left door and drive up the rocky path to find this atop a cliff.

Subway under Divinity Church

Now bust through the right door to find another trophy up some short stairs near a construction machine.

Subway under Divinity Church

Grapple to the highest walkway in the same room to find another.

Subway under Divinity Church

There's one more trophy down here. Drive along the path near the previous trophy. Once you reach the room pictured in the screenshot, grapple onto the structure to the left to find it.
