Condemned 2 Walkthrough

Press the conveyor belt on-switch and the doll boss will approach you. Club her a few times and she'll retreat upstairs. Get to know your surroundings while she does: there is a box of dolls on one side of the area opposite her catwalk, and a first aid kit on the other.

To stop her you'll need to toss the doll grenades at her. She'll always be on one side of the catwalk or the other, and it's easiest to hit her on the left. Time your throws so that she heads right into them.

Eventually, after three or four direct hits, the boss will run off and the catwalk will give way allowing you to reach it. Go up and follow the linear path to the elevator, minding the two blokes on fire. Don't enter the elevator, instead activate the Study Evidence prompt.
