Resident Evil 4 Remake is more difficult than some boss battles because it requires fighting the Chainsaw Sisters in a tight space. Please see below how the Chainsaw Sisters fare in the remake of Resident Evil 4.
On Normal difficulty, there is a light bulb two steps ahead of this place.
I took the crossbow arrows, installed the crossbow bolt mines, and shot them at the light bulbs. Four of them were shot, and I had four.
You can cum two or three more, and they will trigger GG when they come in.
Because I only shot four, they were not powerful enough, and I wasted one extra grenade and two sprays.
