Unlike other Riddler Trophies in Suicide Squad: Kill The Justice League, you won’t be able to get those in the Suicide Slums area early in the game. That’s because Amanda Waller won’t allow you to enter without blowing up your TFX members’ heads.
This means that to be able to collect the three Riddler’s Trophy collectibles; you must progress the story and finish the Dockside Rumble main objective. This objective is mandatory for entering the Slums area in Suicide Squad: Kill The Justice.
Where To Find Every Suicide Squad Riddler Trophy in Suicide Slums
Assuming you want to find the 3 AR Trophies the Riddler projected by yourself, the following map is all you need. But as you know, these collectibles are hard to spot even if you know their locations. So check the tips below, as they also include in-game screenshots.
Riddler Trophy #1: Under the Bridge Leading to Stagg Campus
The first Suicide Squad Riddler Trophy in the Slums district is under the large bridge leading to the Stagg Campus in the Central Business District. The said bridge is found in the southeastern corner of the Slums. Once you reach it, jump down and look for the collectible under some pipes.
Riddler Trophy #2: Next to a Church
The second glowing question mark it’s easier to spot. Head to the location I have marked above (north of the previous collectible) and look for a church. Above its door, you can see a banner which reads: Save our Church. Riddler’s Trophy is hanging on the ceiling of the cover area on the right side of the church’s entrance.
Riddler Trophy #3: In a Tunnel
The third and final Riddler Trophy in the Suicide Slums area is also the trickiest. That’s because it is located underground in a tunnel, even though on my map, it appears to be on the surface. To get this one, head west (towards the beach) of the icon’s location.
Look for a tunnel running under the walls of the citadel where Green Lantern awaits. You’ll be able to see the collectible the moment you enter the passage. It sits above a white door. Collect it, then focus on the three Suicide Slums Riddles or the Central Business District Riddler Trophies.
