Technically, there are no collectibles in The Evil Within 2 Chapter 15, but there are a couple of important, hidden items. In this guide, we’ll show you were to find them.
The Evil Within 2 is full of things to discover, seek out, find and collect. Some of them are useful, like ammo pouches or locker key statues (those knee-high statues scattered around). These get you something immediately(ish) helpful in your journey through Union. The other things you can pick up are just purely collectible. They’re not useful except to satisfy your completionist urges.
High-grade weapon parts
Head through the doorway to the left of the mirror. There you’ll find two high-grade weapon parts.
After you descend the stairs, turn left and follow the pathway around and to the right. You’ll find a Mobius crate with a couple of useful items. (And you’ll need all the items you can get for the fights ahead.)
