In Fallout 3 you could only collect all of the Bobbleheads if you played through the main story line missions. For example the Energy Weapons Bobblehead was located at Raven Rock and only accessible after being kidnapped by the Enclave – which was near the end of the main storyline.
I'm planning my second Fallout 4 character and I don't want them to engage with the main story line after leaving Vault 111, but I do want them to collect all of the Bobbleheads.
Is this possible?
What missions do I have to play to collect all the Bobbleheads in Fallout 4?
Best Answer
If you look at the bobblehead's location, you can see that all of them are located inside freely accessible buildings or areas, except four:
The Perception Bobblehead is located in the Museum of Freedom, and is accessible during the quest "When Freedom Calls", which is the third quest in the main storyline
The Charisma Bobblehead is inside Parsons State Insane Asylum, which can only be accessed when you start the side quest "The Secret of Cabot House".
The Speech Bobblehead is inside a vault, in the room you find a new companion during the quest "Unlikely Valentine", the fifth quest of Act 1. The room can only be accessed by killing a named NPC guarding the door, so is not available otherwise.
The Energy Weapon Bobblehead is inside Fort Hagen. Sadly, it is located in a part that is only accessible through an elevator that is activated only by starting the quest "Getting a Clue", the sixth quest in Act 1.
So in order to get all bobbleheads, you would need to go through the main storyline up to the sixth quest and complete the non-affiliated quest from Cabot. You would still be in Act 1, but the main story line would be pretty much engaged.
