Following the Riddler Hostage side mission you will come to a room with a pressure plate in front of a stage with red curtains the curtains will draw revealing a hostage tied to a chair be sure to have detective mode on for this one as the Riddler cheats in this game you must throw a batarang at the left "?" to save the hostage then glide over and interact with the hostage to finish this part of the side mission.

do you need to find a certain number of Riddler trophies or solve his riddles, because when I input the frequency that the hostage you rescue after the one in the courthouse I keep getting a message from the Riddler saying I don't have enough secrets discovered.

@wolfzero01 Yes, you have to have completed a certain amount of riddles and trophies AFTER rescuing the first hostage for the Riddler to give you the information you need to get to the second Riddler Room, where Hostage #2 is waiting. This is the same for each hostage.

The actual number of challenges needed to do this would be a welcome addition to this solution.

80 Riddler Trophies required.

With detective mode on you need to wait till the hostage rises up before you throw.

I'm up to 91 Riddler secrets found, and I still have not received anything from the Riddler to go after this hostage. Any help?

Took about 15 retires to realize the Riddler is a CHEAT and that you need to use detective vision lol

You will be able to rescue this hostage once you solve 80 riddles. See Genius for the Riddler Challenges guide. Go to the map location that appears after solving the Enigma Machine, break the question mark wall and enter.

This puzzle is a cup puzzle where you must determine which cup the officer is ‘hidden’ under. The Riddler cheats during this and uses a device to move the officer while the cups are shuffling. Use Detective Mode ( for PS4, for PS3) to locate the officer (the left cup), and hit the switch below him with the batarang. Then, rescue him by climbing up a nearby platform and gliding over to him.

The officer will give you new codes for your cryptographic sequencer. Use them, and solve 160 riddles for the next hostage (Puzzler).
