A complete guide of where to find all 8 hidden Bethesda collectibles (also known as Mysterious Objects) for Sebastians office.
Other The Evil Within 2 Guides:
Corvo’s Mask / Dishonored
In chapter 3 you can find Corvo’s mask from Dishonored. The mask is located on a seat inside an abandoned train cart.
Panzerhund / Wolfenstein
You can find the Panzerhund from Wolfenstein in the back of a truck located in the far back of the Treadwell Trucking area.
Rocket Launcher / Quake
You can find the iconic rocket launcher from Quake on the roof of a house in the residential area, to get on to the roof you must climb up via a shed in the backyard.
Bobblehead / Fallout
You can find a bobblehead of Vault Boy in chapter 6 – On The Hunt in The Marrow: Facilities, behind two crates in the corner of a room after you first encounter The Hunter (In the room before you encounter The Hunter a second time, if you miss it you can backtrack back to it).
Action Figure / DOOM
You can find the action figure of Doomguy (also found in DOOM) in chapter 7 laying inside a big bin next to a fallen female Mobius soldier in the Union Business District.
Trophy / The Elder Scrolls
In chapter 12 inside of Sebastians home office you can find a The Elder Scrolls trophy on a cabinet.
It’s located in-between the horse and the box, I took the screenshot after taking the trophy.
Mug / Prey
In chapter 13 you can find a Prey mug behind the reception desk in the Sanctuary Hotel. It doesn’t spawn there until chapter 13, so you can’t find it in chapter 7.
It’s located on the counter, I took the screenshot after taking the trophy.
Bobblehead / The Evil Within
And last but not least you can find a bobblehead of The Keeper from The Evil Within 1 in chapter 17 on a shelf in the living room inside of Sebastians house.
