Some of Fallout 4’s endings are better than others.
The Molecular Level is a dynamic quest that will forever alter the story upon its completion.
So let’s dive in!
Once you rip that chip from the dead courser, this quest starts.
The first step in this mission is tobring the Courser Chip to Dr. Amariat The Memory Den in Goodneighbor.
Once you arrive at The Memory Den, find Dr. Amari.
Of course, Desdemona is hesitant to trust you until Agent Deacon vouches for your encounter with the Courser.
At this point,she will invite you into the Railroad headquarters.
She explains to him that you have a Courser Chip to analyze and then engages you in dialogue.
She then demands that you hand over the chip.
Once Tinker Tom has the Courser Chip, he plugs it into a machine for analysis.
Desdemona says that she would love to work with you more in the future.
Failure to do so, she says, will jeopardize your relationship with the Railroad.
You will need his help tomake sense of the data collectedon the holotape, which looks like gibberish.
Virgil explains that while you were gone,hecreated Signal Interceptor schematics for you to use.
The schematics allow you to build a rig that will hijack the signal the Institute uses to transport Coursers.
The Signal Interceptor will allow you to travel as the Coursers do and teleport you into the Institute.
He also says thatyou promised to retrieve a serum from Virgils laboratory and return it to him.
Choosing one over another may alter future gameplay, especially if youre currently on good terms with every faction.
Below we will go over how this plays out with each faction.
The Minutemen
To seek assistance from the Minutemen,find Preston Garvey.
No matter which response you choose, Preston will ask what the machine does.
Regardless of how you answer,he will tell you to talk to Sturges.
When you talk to Sturges,give him Virgils schematics.
He will look at them for a minute and realize its for teleportation.
He says he can build it, but that he will need some time to get everything together.
In the meantime,you are tasked with building aStabilized Reflector Platform.
Once the Reflector Platform is built, return to Sturges.
Additionally,your map will now have three markersidentifying locations that have what you need.
If you dont have them, then head out to the places marked on your map.
when you’ve got all the equipment, head back to where you built the Stabilized Reflector Platform.
Now that you have those key pieces, you might build the other three items required for the mission.
Build separate generators just for this operation, rather than sucking power from your settlement systems.
If youre ready, he directs you to get on the platform.
The Molecular Level quest is completed once you safely land inside the Institute.
Once there,find Elder Maxonon the command deck.
Maxon will direct you to the Airport settlementjust below the Prydwento get started on building the Signal Interceptor.
Report to Proctor Ingram at the Airport, who is the BOS’s resident techie.
Proctor Ingram will hand you a list of supplies needed to build the Stabilized Reflector Platform.
The list includes the same items as before:ten Aluminum, three Circuitry, and five Steel.
From this point forward, the playthrough is identical to the Minutemen route.
Then,build the components in the Airport settlement.
As soon as the system is powered up, report to Maxon to move the mission forward.
Once Elder Maxon finishes his pep talk, report to Proctor Ingram.
The Molecular Level quest ends when youve arrived at the Institute.
To seek assistance from the Railroad,return to the Old North Church and talk to Desdemona.
She will elaborate on the mission of the Railroad and ask if you support their cause.
Answer as you see fit, but they may not help you if you rub them the wrong way.
After accepting the mission,meet Deacon on the old highway outside of Lexington.
This is the “Tradecraft” quest and must be completed before the Railroad will assist you.
It is also the mission you would do if you joined the Railroad outside The Molecular Level quest.
Once the “Tradecraft” quest is complete, meet Deacon back at the Old North Church.
When you arrive, Deacon will have just finished explaining what happened during the mission.
As soon as you accept, the “Tradecraft” mission ends.
Once she clarifies what the unit does, Desdemona will again direct you to Tinker Tom for technical assistance.
Here’s where things differ slightly from the other factions.
After choosing a place to build the Stabilizing Platform, report back to Tinker Tom.
He will also highlight places that have the items you need.
If youre lacking anything, follow the pin drops on the map to find those items.
Then,apply at least 27 units of electricity, and you are in business!
Desdemona then asks you to make contact with Patriot while youre inside the Institute.
you’re free to accept or decline, based on your preferences.
She also asks if youre comfortable acting as a double agent for them while inside the Institute.
The Molecular Level quest ends upon your arrival at the Institute.
