Escorting Ivy

Meet with Ivy at GCPD HQ: Drive to the GCPD building and park in the basement. Speak with Cash, then head to Poison Ivy’s cell to speak with her.

Scan the Cobra Drone: After a cutscene, you'll be in the Batmobile. Crawl under the garage door to find the Cobra Drone Tank. Use the Batclaw to grapple to high ground and use Detective Mode to scan the tank's weapons, sides, and rear to identify its weakness: the power core on the back. You can use the zoom function if you don't want to get too close.

Destroy the Cobra Drone: Exit the GCPD and use rooftops to scan the tank from various angles. Once its weakness is identified, return to the Batmobile. To destroy the Cobra, sneak up behind it and fire a single locked-on shot at the glowing power core on its back. Avoid its missiles by using the mini-map to track its orientation and its scanning lasers. Utilize Battle Mode for control and use alleys, buildings, and tunnels to stay hidden.

Equip Batmobile Upgrade: After destroying the Cobra, Lucius will contact you about your Batmobile upgrade being ready at the Clock Tower. Head to the objective marker, summon the Batmobile onto the loading zone, and enter the doorway to trigger a cutscene showing the upgrade being fitted.

Take Ivy to the Botanical Gardens: Drive to Miagani Island. Upon crossing a bridge, you'll be informed that three Cobra Drone Tanks have been deployed. Destroy all three tanks using the same method as before: sneak up behind them, lock on, and shoot their weak spots. Isolate each tank and take them down one at a time. Be aware that destroying one Cobra will alert others, so retreat and wait for them to resume patrol patterns before engaging the next.

Complete the Mission: Once all three Cobras are destroyed, drive to the Botanical Gardens on the western side of Miagani Island and park in the designated spot. A story scene will play. Select the 'City of Fear' main quest to proceed.
