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?
