In the final of chapter 3-1, there are 3 cranks that need to be turned up and two of them have to be done by Ashley. Without a rifle, this is how I manage to cover her while she was turning the 2 cranks located at a distance from me.
Most will be using the rifle but somehow I missed taking the rifle earlier. My handgun was running out of ammunitions but I managed to use the handgun and the shotgun to have ashley covered. There are many cultists and you can’t use a shotgun when the cultist was carrying Ashley as this could kill ashley too.
