The Narrows is tearing itself to pieces.

This is just the beginning. If they hit the whole city with toxins, there's nothing to stop Gotham from tearing itself apart through mass panic.

How are they gonna do that?

They'll be using the train. The monorail follows the water mains along Gotham's central hub beneath Wayne Tower. If they get their machine into the station, it'll cause a chain reaction that'll vaporize the city's entire water supply.

Covering Gotham in this poison.

I'm gonna stop them from loading that train, but I may need your help.

What do you need?

Can you drive stick?
