I'm in the sewers, searching for Poison Ivy's second plant. There are three drones I have to disable with the remote hacking device while on foot so I can open a door to let the Batmobile through. However, I can't seem to disable the second drone. It is around a corner and I've died five times trying to find a vantage point.
How do I disable the drones in the sewer so I can open the door blocking the Batmobile?
