When you start throw a stun at her follow her into the hallway and every time she stops to shoot at you trow more stuns at her,when the black smoke comes up run away,then use the ENV. solid eye to find her,When You Find her
use ur seepin dart pistol shoot her in the head,then she deploys the black smoke and then you run again she will come threw 1 of the windows then use ur stuns againand keep dodging and running from her attacks when she starts to roll get up on a desk or bed then stun her.Hope This Helps.
