The last set of Riddler Trophies you must locate in Suicide Squad: Kill The Justice is found in the Central Business District. Since it’s larger than all other districts in Metropolis, after you unlock it via story progression, you’ll have to look for nine green question marks.
In this guide, I’ll tell you where to find all of them so you can unlock the corresponding trophies and achievements. Before we start, remember that in Central Business District, you also have to solve 3 Suicide Squad Riddles.
Where To Find Every Suicide Squad Riddler Trophy in Central Business District
The exact locations of the projected AR versions of Riddler’s Trophies are marked on the following map. However, if you struggle to find them, you can check the in-game screenshots and tips below.
Riddler Trophy #1: Inside a Chinese Lampion
The first hidden Trophy in Central Business District is hands-down the trickiest in the game. That’s because it is found inside a Chinese lampion at the location marked above. Make sure that when you look for it, you check the upper section of the area, not the street level.
As you can see in the following screenshot, the lampion is hanging above a platform that interrupts the train tracks. Shoot it down to be able to collect it.
Riddler Trophy #2: On the Ceiling of Lexcorp’s Entrance
On the other hand, the second Trophy is very accessible. Look for it on the ceiling of the entrance to Lexcorp HQ, where you get to visit Lex Luthor.
Riddler Trophy #3: Inside the Head of Lex Luthor’s Statue
After you get the previous one, head south and climb Lex’s destroyed statue. The next collectible is inside the statue’s head.
Riddler Trophy #4: On Top of a Skyscraper
The fourth green collectible is also very accessible. You’ll find it on top of a skyscraper at the location I have marked. It is southeast of the previous Trophy.
Riddler Trophy #5: Next to a Statue
Only several meters from the previous collectible, you’ll be able to find the next one. It’s sitting next to a statue inside a gazebo.
Riddler Trophy #6: On Top of Metropolis University
Once you get the previous Riddler question mark, head east and climb the Metropolis University building. This Trophy sits on the tower.
Riddler Trophy #7: On Top of a Platform Inside Kord Industries
The next Trophy also marks an important landmark – Kord Industries. Travel to the location on my map and get inside the building. The collectible sits on top of the statue in the small courtyard.
Riddler Trophy #8: Under a Plane
For the eighth collectible, check the Berkowitz Airport at the location on my map. Enter the underground hangar, where you should spot a plane. The Riddler Trophy is hanging on the platform beneath the aircraft.
Riddler Trophy #9: On a Bridge
The last Riddler Trophy in the Central Business District is also very accessible. Just head to the bridge in the northeastern corner of the region (location marked on my map above) and climb to the upper level. You’ll find it in the area below the roof.
After you collect this one, you should unlock The Oldest One in the Book! Trophy/Achievement, assuming you found all other collectibles. If it doesn’t pop, refer to our Suicide Squad: Kill The Justice guides to get all of them.
