The Evil Within 2 has a number of hidden Easter eggs stashed throughout its chapters, all of which are references to other Bethesda games; Doom, Prey, Quake, The Elder Scrolls, Dishonored, Wolfenstein, Fallout and the original The Evil Within.
And finally to top it all, there’s also a bobblehead of your old buddy The Keeper from the original The Evil Within.
Those action figures you found lying around in Doom also happen to be in The Evil Within 2.
You can pick this up during Chapter 6 – On The Hunt in The Marrow: Facilities, but it involves backtracking.
