Bleake Island: the first Riddler sweep

A Riddler sweep with no story steps: Chinatown from the broken ACE Chemicals bridge to the Clock Tower, then The Cauldron down to Falcone Shipping, then the grounds and roofs of Panessa Studios.

Mercy Bridge can wait: this stretch clears everything Bleake Island offers so far. You carry the Batarang, Remote Controlled Batarang, Batclaw, Explosive Gel and the Grapnel Gun with its Boost, and the Batmobile has its 60mm Cannon, Afterburner, Power Winch and Forensics Scanner. Left for later: anything that needs the Remote Electrical Charge or another gadget you don't own yet, and the challenges that only appear as the story moves on.

Riddler informants

Interrogate every Riddler informant you pass: each marks challenges on your map, and the map lists how many of each kind remain. One or two marked trophies will stay out of reach at the end of this sweep.

Stolen cars

On foot, you will see thugs driving stolen cars. Let one try to run you down and counter just before it hits to stop and disable it. The Real Deal needs 20 of these, so take them whenever they come.
