Matthias and Ryan lead the two civies to a commercialized street and then to the middle of an intersection. They stopped at a manhole. Matthias moved out into the intersection and kept spinning to make sure no one could sneak up on them. Ryan, meanwhile, dropped his pack and picked up a crow bar. He peeled back the manhole and put the crow bar back on his gear. He dropped his pack down the hole and started to climb down after it. Matthias turned around and motioned for the civilians to follow. The smell of the sewers were bad, but there was no running water there.
