This guide shows how to find The Evil Within 2 Flamethrower Location and repair it in chapters 11-13.
Step 1 (Chapter 11):
After the Flamethrower boss fight, pick up the broken flamethrower next to the corpse of the boss.
Step 2 (Chapter 13):
The flamethrower is broken and you must find two fuel tanks to repair it. You can collect the tanks from Harbinger enemies that are roaming around chapter 13. There are 3 of them in the business district (it’s literally impossible to not notice them, you go there to the next main objective). Sneak attacks deal a ton of damage to them. You can run away after a successful sneak attack and repeat. This way you don’t have to waste ammo on them. Sniper headshots and close range shotgun hits also work well. Just loot two Harbingers that you’ve killed to receive their fuel tanks.
Step 3 (Chapter 13):
Head to the safehouse and enter the mirror. At the workbench you can combine the fuel tanks with the broken flamethrower to repair it.
And that’s how you get the Flamethrower in The Evil Within 2!
