Search the following locations to find the corresponding trophies:
2. East of Trophy 1 on the roof near a wall with five Riddler question marks on the wall. Use the Batarang to destroy the right-hand Riddler mark by waiting until the light is on.
3. On the building north of ACE Chemicals, behind a ventilation system. Use the remote controlled Batarang to destroy the Riddler mark.
4. On the roof of the building with Park Row written over it on the map. The timed panel is a few steps to the west.
5. On top of the most northwestern building near Solomon Wayne Courthouse. Use detective vision to locate all four Riddler marks. You have 4 seconds to destroy all four marks, so use the explosive gel on the 3 hidden marks, then use the Batarang on the final Riddler mark closest to the trophy’s locked cage.
6. There are three pressure pads in the area. Starting from the northern rooftop overlooking the Riddler trophy, glide on to the southern wall and pressure pad. Quickly after pressing the pad, glide over to the wall on the opposite side then finally onto the pad on the ground closest to the Riddler trophy.
7. A pressure pad on the highest rooftop east of Solomon Wayne Courthouse opens a gate below. Activate it then glide down into the area, then use explosive gel to destroy the wooden panel beneath.
8. Slightly southeast of Trophy 7. On top of the roof with a nearby Riddler mark on a chimney. Use the Batarang to activate it.
9. On the northern roof edge of the large building east of Solomon Wayne Courthouse. Use explosive gel to destroy all three Riddler marks at once.
10. In a passageway at the most northern part of Park Row. Behind a chain fence with a destructible wall on the right. A TYGER camera guards the area.

12. East of the building between the north side of the restricted area and the Church/Medical Centre, opposite a building with a "The Black Canary" sign. Use detective vision to locate the necessary Riddler mark, then use the remote controlled Batarang to activate it from near the Riddler trophy.
13. On the roofs of the buildings west of ACE Chemicals and north of The Bowery is a set of cages with electromagnets. Once you have the REC, use the electromagnets to push the Riddler trophy out of the cage, starting with the bottom electromagnet.
14. Near west side edge of Arkham City, on the roof behind a set of bars. This TYGER panel will require the necessary upgrade before you will be able to hack these controls.
15. In a short passageway along the west wall of Arkham City. Guarded by a TYGER Camera.
16. West of ACE Chemicals, on the roof of the building that runs through the Arkham City wall. Activate the panel by gliding from the top of the nearby gargoyles on the Bank Of Gotham, then use dive bomb to land on the panel. Destroy the Riddler mark with the Batarang.
17. At ground level below ACE Chemicals. Access the cage by freezing the hot air with the Freeze Grenades.
18. Beneath an abandoned car west of ACE Chemicals. Bat-slide underneath it to collect it as you go.
19. Behind a set of iron bars west of ACE Chemicals and next to a short barrier with a "Do not enter" sign on it. Glide from the roof of the building to the north to smash through the destructible wall.
20. On top of the church's roof, locked by a nearby TYGER panel.
21. On top of the church is a short passageway with an electrified fence and a destructible wall. Use the REC on the fusebox and explosive gel on the wall to collect the Riddler trophy.
22. In the alleyway behind the church is a cage with a set of pressure pads. You won’t be able to access this without the Line Launcher, since stepping on the red Riddler pressure pads will close the trophy cage above. By using Catwoman you can collect this trophy much early. Hop onto the ceiling above the pressure pads and scurry towards the end of the cage. At the top platform Catwoman can collect both her trophy and Batman's trophy, providing you didn't somehow activate the red pressure pad. – thanks to Belthizor

4. Above the Scarface display in the trophy room is a vent. Use the Batclaw to dislodge it then climb through to the next corridor. The trophy is protected by a TYGER camera.

7. Above the last Riddler trophy is a cage with an access grate. The trophy is inside here.

10. From the top of the Gladiator Pit guide a remote controlled Batarang through the electrical current and back around into the fusebox in the central corridor with the locked gate.
11. From the last trophy, smash through the window at the end of the corridor and walk around to collect the Riddler trophy.

2. Just behind that hot air is another Riddler trophy. Stop the air and gain access to the trophy.
3. Jump through the glass window at the end of the first corridor. The trophy is inside here, but its cage will close whenever you enter. First, use explosive gel to destroy the left-hand destructible wall. Then make your way around the room so you can see through the now-open window and use the Batclaw to grab the trophy.
