The Cobra tanks and the Botanical Gardens

The end of Heir to the Cowl, then Chinatown and the GCPD, the first Cobra tank and the EMP, a Bleake Riddler sweep down to Panessa, then Miagani's three Cobras and new militia sites, the Botanical Gardens, the Sonar and a Bristol sweep out to the Ferris wheel.

The airships are behind you and the story turns back to Chinatown, where you finish Heir to the Cowl first. You now carry the Remote Hacking Device, Disruptor, Remote Electrical Charge, Freeze Blast and Line Launcher, with the Power Winch and Forensics Scanner on the Batmobile, and this stretch adds the EMP and the Sonar. The story can wait: new Riddler Informants appear on Bleake here and on Miagani after the crossing, so interrogate them as you go. Left for later: everything that needs the Voice Synthesizer, the Two-Faced Bandit robberies, and the Kingston and Grand Avenue Riddler challenges, including the cage marked in The Cauldron, whose switch is on Miagani.
