Locate Scarecrow

Meet Oracle at the Clock Tower: Grapple to the Clock Tower roof, use Detective Mode to find the secret entrance, and enter. Inside, use Detective Mode to find a retinal scanner on a bookshelf. Activate it to alter the room and use the computer console.

Use the Panessa Studios antenna: Use the Batclaw to exit the Clock Tower. Travel to Panessa Studios to the east. On the roof, interact with the marked circuit board to attach a Remote Access Device. After speaking with Lucius, the Batmobile's Power Winch upgrade will appear by the lighthouse southeast of the studios. Go to the ground-level objective marker and trigger the upgrade scene.

Power up the Panessa studios antenna: Enter the Batmobile's battle mode and use the Power Winch on the nearby sign's anchor point. Drive backward to pull it down. Drive up the ramp and use the Afterburner to jump to a nearby rooftop. Enter Battle Mode, use the Power Winch on the raised section of roof to create a ramp, and reach the next level. Follow the path to the western side of the roof and use the Power Winch on the anchor point to swing to another building. Drive up the wall to access a balcony and return to the panel where the Remote Access Device was inserted. Use the Power Winch on the panel and complete the mini-game by pumping the accelerate button to keep the needle in the orange segment.

Use the antenna at the Falcone Shipping Yard: Head to the next objective marker to the south. You'll encounter Scarecrow's men guarding the antenna. Use Detective Mode to scout the five armed enemies inside the building. Throw a Batarang to lure two enemies out, then perform silent takedowns. After dealing with them, retrieve a new Batsuit and unlock optional AR Training sequences. Return to the building, enter the grating, and crawl beneath the thugs. Initiate a Fear Multi-Takedown to eliminate up to three enemies at once.
