Alan Wake 2

In Return 2 - The Heart, after you turn the light on in the Witch's Hut you'll have to go to the General Store. From here, you should have your first encounter with a Cultist. After this, go into the room he broke out of & to the right below the Display Case where the Sawn-Off is, you should find a package type thing. This'll immediately upgrade your inventory.

Happy Hunting, Hunters. 💜
