Bethesda has hidden some mysterious objects in The Evil Within 2 and the most awesome thing about them is the fact that they are objects from other Bethesda games.
Dishonored, Quake, Wolfenstein, Fallout, Doom, Elder Scrolls, Prey and The Evil Within (OG) all have items that you can find across a number of different chapters and locations.
MYSTERIOUS MASK – DISHONORED
Available in Chapter 3: You can find the Mask in one of the derailed trains along the western edge of the Union Residential District. More specifically, it is the second car just past the overturned van.
