How to unlock the Nuclear Family achievement in Fallout 4 - Definitive Guide

This is the last achievement in the Institute questline.

While the other solution already shows how to get this achievement, I wanted to share a chart I made with the way of getting all the story achievements with only one save / reload, and also the best point to save in order to obtain all 4 endings (not necessary for achievements).

Scroll down for a more detailed explanation (inside the Spoiler Tag, as it is an awful lot of text).

For starters, keep in mind a thing: having high charisma will help you when you'll have to balance several factions at once. I recommend having at least 6-7 points of charisma, and using "charisma-enhancer" gear like Glasses, Hats or Suits, or even using, when neccessary, beer or some drugs as Grape Mentats or Day Tripper that give charisma points for a few minutes.

Open this thing for the full explanation:

START MAIN MISSIONS

As soon as you're out in the Commonwealth, you'll be able to explore freely. Follow the main quest for a while, and, after completing the quest "Reunions" the Brotherhood of Steel will be available. That moment, or a little later (after "Shattered", for example), is a good time to join the available factions and advance on their questlines. I recommend advancing until your current mission is "The Glowing Sea", that way you'll have a higher level to face these missions.

The Unlikely Valentine achievement in Fallout 4 worth 26 pointsComplete "Unlikely Valentine"

The Reunions achievement in Fallout 4 worth 27 pointsComplete "Reunions"

The Dangerous Minds achievement in Fallout 4 worth 28 pointsComplete "Dangerous Minds"

JOIN THE FACTIONS

You'll probably have met the Minutemen already as you came out of the Vault. Their questline starts with "When Freedom Calls".

Once you complete the mission, make sure you complete "Sanctuary" too, as it isn't necessary for progression but it has an achievement.

The Sanctuary achievement in Fallout 4 worth 25 pointsComplete "Sanctuary"

"The First Step" is the mission in which you join the faction, and it unlocks a series of secondary missions related with helping settlements.

The The First Step achievement in Fallout 4 worth 12 pointsJoin the Minutemen

Do three of these secondary missions, and the next mission, "Taking Independence", will be available. Do it, and then the next one, "Old guns". Upon completing these, you'll have all Minutemen achievements, and you can forget of this faction for the rest of the game if you wish.

The Old Guns achievement in Fallout 4 worth 45 pointsComplete "Old Guns"

Time to join the Brotherhood. You'll find a military radio channel that will lead you into a police station, where you find some Brotherhood members. You'll have to complete a few missions until you become a member. "Reveille", "Fire Support", "Call To Arms", and, finally, "Semper Invicta".

The Semper Invicta achievement in Fallout 4 worth 13 pointsJoin the Brotherhood of Steel

You can do a few more quests for them, and I reccommend to do it. These are available after you complete the main mission "Reunions", and are "Shadow Of Steel", "Tour Of Duty" and "Show No Mercy".

Railroad time. You'll only be able to do a couple of missions for them at this point. These are "Road to Freedom" and "Tradecraft", in which you join the faction.

The Tradecraft achievement in Fallout 4 worth 15 pointsJoin the Railroad

Okay, time to continue the main missions.

CONTINUE MAIN MISSIONS

After "The Glowing Sea", you'll complete "Hunter / Hunted"

The Hunter/Hunted achievement in Fallout 4 worth 29 pointsComplete "Hunter/Hunted"

And here the decisions start. In the next mission, "The Molecular Level", you'll need to

Make sure you choose the Railroad, to ensure you can access everything later.

The The Molecular Level achievement in Fallout 4 worth 31 pointsComplete "The Molecular Level"

Next mission is "Institutionalized". And here, you are offered another choice. You need to

The Institutionalized achievement in Fallout 4 worth 15 pointsComplete "Institutionalized"

CONTINUE WITH FACTIONS

Time to deviate from the main quests and work in the factions again. As soon as you complete "Institutionalized", start "Underground Undercover" for the Railroad, and advance in the quest until your objective is

Then, switch to Brotherhood missions. Complete "From Within", "Outside The Wire" and "Liberty Reprimed". Now "Blind Betrayal" will be available, but DON'T COMPLETE IT. If you do, Railroad quests will turn unavailable. So, let's get back to the Institute.

REACH THE DIVISION POINT

Complete "Synth Retention". Then, in "The Battle Of Bunker Hill", you'll have two optional objetives. Choose to

and, at the end of the mission

Complete the next mission, "Mankind - Redefined".

The Mankind-Redefined achievement in Fallout 4 worth 18 pointsComplete "Mankind-Redefined"

This is the DIVISION POINT where the different paths to the ending start. I believe this is a good moment to get all miscellaneous achievements done (Bobbleheads, Miscellaneous Quests, Secondary Quests, Giant Enemies, Settlement Hapiness, etc) so you can then pick tne ending you want and conserve all of the benefits of these tasks.

And here's the important point. As soon as the next mission, "Mass Fusion" asks you to make a choice, MAKE A MANUAL SAVE. I'd create 3 or 4 saves in that moment, for precaution. Write the location and time of the save in a piece of paper so you can recognise it easily later on.

And now, you'll have 2 different paths to the ending.

PATH 1: RAILROAD + INSTITUTE

In "Mass Fusion", choose

This will turn you into a permanent enemy of the Brotherhood, making their quests dissapear. But you can still work for the Institute and Railroad.

Complete "Pinned" and "Powering up" for the Institute.

The Powering Up achievement in Fallout 4 worth 20 pointsComplete "Powering Up"

As soon as you finish "Powering up", you can finally complete "Underground undercover" for the Railroad. Do so.

The Underground Undercover achievement in Fallout 4 worth 25 pointsComplete "Underground Undercover"

Continue with the railroad questline. Dependind of the secondary missions you have done for them, you'll have to do a quest named "Operation Ticonderoga", or you may jump directly to the next mission, "Precipice of War". Anyways, complete those and the next one, "Rockets' Red Glare", for the last Railroad achievement.

The Rockets' Red Glare achievement in Fallout 4 worth 76 pointsComplete "Rockets' Red Glare"

Stop here, because the next Railroad mission ends the main questline. Time to go back to the Institute and complete their missions (You can make another save here and go back later for the Railroad ending, if you wish). "End Of The Line" will turn the Railroad hostile, and, because you already did "Rocket's Red Glare", you'll skip "Airship Down" and jump directly to the final Institute mission, "Nuclear Family".

The Nuclear Family achievement in Fallout 4 worth 66 pointsComplete "Nuclear Family"

And if this is your fist "final mission", you'll get the achievement for completing the main storyline.

The Prepared for the Future achievement in Fallout 4 worth 86 pointsDecide the Fate of the Commonwealth

PATH 2: BROTHERHOOD

In "Mass Fusion", choose

This will turn you into a permanent enemy of the Institute, making their quests dissapear. You'll be able to work for the Railroad at this point, but we won't do that.

As soon as you finish "Mass Fusion", "Spoils Of War" will be available. Complete it (make a save here if you want to do the Minutemen ending later), and go on the next quest, "Blind Betrayal". Now we can complete it without messing the other achievements.

The Blind Betrayal achievement in Fallout 4 worth 20 pointsComplete "Blind Betrayal"

Why do I say that? Because, as soon as you complete this quest, the next, "Tactical thinking" will start automatically... and it will block the Railroad quests, making them unobtainable. But at this point tat doesn't matter, because we will obtain them in the other path.

After "Tactical Thinking", complete "Ad Victoriam"

The Ad Victoriam achievement in Fallout 4 worth 67 pointsComplete "Ad Victoriam"

And, finally, "The Nuclear Option".

The The Nuclear Option achievement in Fallout 4 worth 57 pointsComplete "The Nuclear Option"

Railroad and Minutemen have their own "Nuclear Option" too, but only one of those is required for the achievement. So if you don't want to end the game with the Brotherhood, reload one of the two optional saves I mentioned, and complete the game with either of those factions to get the achievement.

Hope it helps!

I won't be spoiling anything story wise just going what you have to do. Just trying to get everyone one play through and 1000g

Here is the link for key info and I hope everyone is following this.

The Hunter/Hunted achievement in Fallout 4 worth 29 pointsComplete "Hunter/Hunted"

The The Molecular Level achievement in Fallout 4 worth 31 pointsComplete "The Molecular Level"

So this mission is very easy if you sided with the Institute during Instutionalized also i pray for you that you made the saves like I said..

*Edit 1* So during Mass Fusion for Institute before you use the relay save as this quest makes the BoS hate you. So... Up till this quest you're good to do everything for all three factions. If you are about to make a faction hate you, you will get a notification. cancel and save before.

And you're good up until End Of the line for the Institution for the Railroad

That being said you can obtain this and ASquishyHamster but only if you save before EITHER mission and if you sided with the railroad. So if you sided with Railroad you can do their quests and Institution quests, BUT NOT THE BoS.

You will need to have completed these quests for the Institution to get to this point. I will explain each mission to an extent.
1. Synth Retention - Synth went rouge now you have to retrieve it.
2. The Battle of Bunker Hill - You're going to a settlement of Synths to deal with them. After you're done talk to father again
3. Mankind Redefined - You're just going to attend a meeting
4. Mass Fusion - If you're loyal to the Institute and side with them you will fail BoS quests.. Or you can tell the BoS and this begins Spoils of war. (side with Institute for progress to listed achievement.
5. Pinned - Make sure you're friends with the Minutemen before this because you can ask them to stand down, you tell them it's and order.
6. Powering Up - Record Father. Give tape to Diamond city. Fast travel back. Initiate core start up. You get to decide whether they build up man power or weapon power (doesn't matter)
7. End of The Line - Speak to Father, kill Desdemona and Railroad leaders.
8. Airship Down - Infiltrate the airport, destroy the three generators. (bring a missile launcher for the Vertibirds and plenty of missiles) reach Liberty Prime protect the Synth as it reprograms Prime.

Then you will be at Nuclear Family as the final quest for the Institution

Anyways this is very easy.. Talk to the old man... Like I said if you've followed my other guides this will be the easiest one you've ever done. But this mission is after you've done Airship Down. Talk to the old man and BAMM 30G

I think some people were confused. Its a bit tricky to follow your solution if you just know the names of the missions, just guessing. Keep up the good work :)

By Notarzt on 14 Nov 2015 16:51

Thanks for the guide. I... What a great ending. Maybe my favourite.

By THEpaynexkiller on 15 Nov 2015 04:45

Unobtainable if you follow right through with the brotherhood of steel and nuke the life out of those slimy institute bastards

By Nuka Cola Cap on 14 Nov 2015 08:33

For those that gave negative feedback please explain why you did.

By The Hodge XBL on 20 Nov 2015 20:12

Thanks man! This worked perfect for me. I saved right before the mass fusion one, and by following your guides I am able to go back and do each faction.

By Clownz on 22 Nov 2015 06:13

This was much better than your other F4 solutions. The only confusing thing was that the Institute mission "Airship Down" was completely skipped. It went from "End of the Line" directly to "Nuclear Family". +1

By justG0Twicked on 25 Nov 2015 04:12

nice its because you must have done something for one other faction that the institute wanted but you already did

The final institute main quest. This is quite simple, albeit a bit touching, of a quest.

1. Make your way to the Institute, and navigate to Father, who is in his deathbed

2. Speak to him and offer your son some final parting words

3. Shawn passes away, and the ending cutscene for the game begins

Notes:
Once this quest is completed, Father's memorial will appear in the Institute in front of the Robotics division, and Institute synths will patrol the Commonwealth's military checkpoints.

If the player kills Father before his natural death, the player will become enemies with the Institute, and this quest will still complete.

MISSABLE! - One of two endings. You can only get this ending if you went through all the quests for the Institute, and didn't cause them to banish you. You will get banished if you help other factions to the point where it makes the institute hostile. See the Roadmap for more information on what can lock this quest out. The game will tell you prior to an action if it will make the Institute hostile so don't worry too much.

This trophy can be achieved by finishing the final quest for The Institute. See the spoiler below for more information. The reason this trophy is missable is you can cause the Institute to banish you if you advance too far into one of the 3 factions (Minutemen, Brotherhood of Steel, Railroad). The game will tell you when it's about to turn a faction hostile so do not worry about it randomly happening.

The Institute is the only faction that will lead you to this achievement. This is the endgame achievement that runs opposite of "Nuclear Option." Simply follow the Institute's storyline until the end to unlock this ending.

I got the trophy with the support of the Underground. If I had listened to the hints above, I would have gone through the story from the Molecular Level in vain once again. So, there is no need to give up the Underground.
