PARK ROW - RIDDLER TROPHY #26
You’ll need to chuck your batarang at each panel when it lights up. They light up in a certain sequence, so study the pattern and try to anticipate.
PARK ROW - RIDDLER TROPHY #27
You may spot this trophy long before you can reach it. You need to create an ice platform using the freeze blast, and then use your grapnel to pull yourself over to the trophy.
PARK ROW - RIDDLER TROPHY #28
On the church roof, smack dab in the middle. You only need the cryptographic sequencer to use hack the nearby panel.
PARK ROW - RIDDLER TROPHY #29
In the alley behind the church you’ll see four riddler panels. Stepping on the first unlocks the trophy cages above, but you need to somehow get over the other three red panels or the cage will close again. Use the line launcher and attach it to the far left wall (the fence directly in front of you won’t work). Turn around and grapple up to claim the trophy.
PARK ROW - RIDDLER TROPHY #30
This one is located south west of the church. Use the remote electric charge to disable the electricty, then use your explosive gel on the left wall.
PARK ROW - RIDDLER TROPHY #31
Turn on detective mode and follow the wiring to find a riddler panel high above this caged trophy. Hit the panel with a batarang then quickly drop down before the cage closes.
