Rescue the Orderlies Held Hostage in the Aviary

After speaking to Jordan, head down the stairs, check the bench on the left for an Interview Tape then proceed through the door into the Aviary.

Take Down the Henchmen Leader

Alright, so a couple of hostages are suspended in a pair of hanging cages, and they're guarded by four henchmen wandering around, each equipped with one of those security collars. As such, you'll have to take down the main operator within the control room without harming or alerting the others. To do so, start off by crouch-walking up to a vent on the left--take it slowly and make sure the guard at the end of the path turns away before entering. Grapple up the wall within to a vent at the top. You'll exit onto a ledge--glide to a pathway along the left wall, just above one of the guards. Now grapple up another ledge, then drop to the ground ahead--you're almost there! There's a guard on the walkway just overhead--grapple onto the railing and sidle along it to the right, close to the ladder leading into the contorl room. Now wait for the guard to turn around before climbing up, and take down the operator

With the Operator down, you simply have to kill the remaining three henchmen to free the hostages. Simply follow the path back and use Stealth Takedowns as you encounter each of the three guards (just make sure to wait for the first to turn away before approaching). After freeing the hostages, check a nearby bench for an Interview Tape.

Now you have to look for the lab's hidden entrance. Use Detective Mode to follow Quinn's fingerprint trail up the first ledge (directly opposite the the freed hostage's location) to find a hidden panel that can be ripped off revealing a console. Use the Sequencer on it to discover a hidden doorway, leading into the Production Facility.

Inside the Production Facility, you'll have to take on two of the Joker's roided-up brutes. Although you'll initially battle them like Bane before--that is, quick-toss a Batarang at them while they charge at you, then dodge out of the way and punch them when they hit the wall--there's a new technique you can use. After a few punches, they'll fall over stunned--run up to them and press the attack button again to climb up on their back and ride them around! Simply steer him toward the other one, where he'll begin to pummel his friend--sweet! Just keep alternating between the two to inflict an even amount of damage.3
