To Kill Boaz You need to shoot her face with quick shots to avoid her devasting attack on you.Then when she starts shooting green acid balls, run around to her side and press square to reaim at the acid throwers.Shoot at one of them until she jerks.Continue to do this until all the of the acid throwers are blown out.She will roll over and appear to be dead.... THEN she will re-emerge as a fly.This boss is relatively easy to kill.Her attacks are easy to dodge but just stay away from her and shoot.To prevent losing health from the first Boaz avoid the acid at all costs.Don't step or jump in it.
