Chloe's only weapon was a pistol she brought from home, which has barely any ammo left. Not that it works well against shadows. She's likely going to take Saul and Ico's method of "hit them with a stick" unless some one has another weapon she can borrow. She's not exactly skilled with anything but that hasn't stopped her in the past. She's just not content to sit on her ass for this one, even though these things terrify her.
