The Evil Within CH6: Cabin Fight - First Burning Room Strategy. No shock bolt WIP. NG/AKUMU/NoUg

Trying to find the best way to use the shotgun instead of the shock bolt, and save 4 parts. This video contains some examples quickly edited together. This is from a NG/AKUMU/No Upgrades save file, and very much a WIP (I still end up running in circles in a few attempts, and died quite a few times!) I've temporarily changed the FOV while learning how to do this.
Things to watch out for:
1. Distance is key with the shotgun - too close, and you will kill them with the bolt. Too far and the shot isn't going to slow them down. I need to find the sweet spot I can place myself each time.
2. Knifey Haunted - can duck if you aim at her outside. Possibly I was standing too close that time.
3. You can out-of-bounds knifey to the right, but the timing is easier to the left. So my gut tells me to shotgun knifey, bolt the 2 on the left, and wait for knifey to return and bolt to the left. Undecided on this one. Update to this: I am actually preferring shooting the 2 on the left, pivot without moving and bolt knifey to the right out of bounds, then deal with the left 2 with bolts.
I am probably sticking with a shock bolt for the time being, but I'll keep trying this. A better player will probably have no problem with the shotgun method.
