Fallout 4 - All Mission Achievements In One Playthrough

How to obtain All the Achievements with only one save / reload

About Guide

While the other guides are helpful, they are rather chaotic, so I made a chart that shows how to obtain all the achievements with only one save / reload. My guide shows how to unlock "The Nuclear Option" while aligned with the Brotherhood, but I also indicate when to diverge from these steps, if you want to play the Railroad or Minutemen endings.

What about DLCs Mission Achievements?

Achievements from the Far Harbor DLC are not missable so if you just continue with your playthrough you will get them all.

Achievements ("Raiding for a Living" & "Hostile") from the Nuka-World DLC however are missable if you become enemy with raiders (murdering any gang member after you've exited the Gauntlet). So in short do not do not become enemy with the raiders before completing Story achievements and "Raiding for a Living" & "Hostile Takeover" and you will get them all! :)

Thank you very much for reading this guide!

Just used this myself, thank you!

very confused on the underground uncover part in the center section. I don't see where is says "Continue working for father". It's asking me to kill guards in the mining bay and if I do, then the Synth Retention Fails. What am I doing wrong?

its sad you cant earn achivements with mods

[VanBongh]

yeah bro optional is optional

[ChupaChup]

Coming back to say I just completed this following the instructions to the T and got all of the achievements. So glad I didn't have to do the optional saves for "Nuclear Option" after doing the Brotherhood ending.

For anyone curious, it's the same achievement no matter who you decide to destroy the Institute with.
