InFAMOUS/Secrets Revealed

Your first job is to track the chopper through the Warren. Instead of watching the chopper, watch the mini-map and the full map and use every wire you can find that goes in the general direction of the marker. When you get near the bridge to the Historic District, you'll have to fight a Conduit trashbot.

You won't take that much damage from the tank explosion, if you're worried about following the Heroic path. You then have to destroy the Conduit, which is much easier now that you have Polarity Wall to use against its machine gun.
