Here's the Lower Hengsha sewer theme. Of course the scenery isn't much to look at so displayed is the abandoned noodle factory where the track also plays. But like Detroit's sewer theme, it's a great track.
Gameplay tips: It's fairly easy to get into the factory as there are only 4 guards in the sewer. Once inside, you can either bypass the guards or take them out via I&I by bringing one guy up to second level at a time. Just remember to turn off the cameras in the room with security PC.
