How to unlock the Conundrum achievement in Batman Arkham City - Definitive Guide
You need to proceed to the courthouse where a fight will ensue and you'll save a hostage, this is not the one intended for the achievement. Afterwards you'll receive your first radio frequency for the Enigma Box riddle which will unlock the location of the first hostage to save for the achievement in question.
Follow the marker for the Riddler Hostage side quest now and you'll find a ? symbol painted on the wall, *also a political assualt you can stop if you haven't yet*. press "A" on it and Batman will knock on the wall and open the path to the door. Once inside the first door turn around and there'll be a ? with a switch to hit with a batarang to open the door to the main room.
**If you've unlocked the line launcher you can skip over all the panels and Riddler makes a crack about you cheating**
Inside the main room the floor consists of electrified panels connected to the lit up ? marks on the walls, hit the corresponding ? with batarangs and progess along the safe path before time runs out to the next dead panel. Advance this way until you make it to the lift then glide to the platform with the hostage to free them. The hostage will give you another frequency with the next riddle for the Enigma box and your next hostage location (provided you have enough Riddler trophies found)
Below is my video guide showing how the room can be solved.
you will come to a room filled with electric pads on the floor, turn on detective mode look for the "?" symbols on the walls, throw a batarang at the "?" symbols to make the pads turn off follow the now un-electrified pads to the next safe pad rinse and repeat till you get to hostage
The first hostage will be marked on your map once you complete IQ Test, it’ll be south once you leave the church. There will be a wall marked with a green question mark. Curiously, you can’t blow it up with explosives, instead you must walk up to it and press . Batman will then break it down with bare fists, and you can enter this building.
Here, you must rescue a hostage using your gadgets. Once you enter, turn around and use your batarang to hit a question mark switch above the front door you came in. Enter the next room. This puzzle requires you to use the batarang to hit question mark switches, which will shut off electrocuting tiles that you’ll have to walk across.
Throw a batarang to the switch ahead of you, then run across the tiles it shuts off. The next switch is to your right after you sprint across the first tile set. Throw a batarang at the first switch again, which will activate the last set of tiles to an elevator. The final switch is to the left of the door you entered from, which will activate the elevator. Glide to the hostage to rescue them.
After the puzzle, you will receive the Enigma Machine, which will point you to your next hostage using the cryptographic sequence, which will become available once you solve 80 riddles (Mastermind). See Genius for the Riddler Challenges guide.
