KNIFE BEATS CHAINSAW
Kill the Chainsaw Boss In The Barn With a Knife
The Evil Within KNIFE BEATS CHAINSAW – Achievement / Trophy Guide
Before taking on the boss in the barn, climb the tower and get the flash bolt. It’s also a good if you search the town for ammo.
Once you face him, weaken him with explosive bolts or other weapons and then switch to the flash bolt and shoot him. That’s your chance to sneak attack him from behind. Depending on how much you damaged him before, you might have to repeat once or twice. You can also craft flash bolt if you run out of ammo.
