Downtown/Construction site

First Drain Deimos in the game appears in the cutscene here. Also, Brain Suckers may appear here, when Jill returns to the Uptown. Wooden box hanging on the rope in that area is destroyable object and can be shot, so it'll take damage to the enemies if it falls to them. Exploring dead body of the mercenary, Jill can find Gun Powder A.

Also, there's inactive elevator in that room. A Battery must be set to the slot to activate it.
