The Institute-Railroad Alliance Alternate Ending

Patch 4. 0B

fUe8NWo92QA

An immersive alternate Railroad and Institute ending that allows the reformation of the Institute and peace between the Commonwealth factions. Free the synths, end the kidnappings, stop the immoral experiments, pacify the Brotherhood of Steel with less violence. 4 new companions are available: Z1-14, Glory, Super Mutant Virgil, Synth Elder Maxson.

Requirements:

There are no special requirements beyond vanilla Fallout 4.

This mod is out for PC and Xbox One. There is no PS4 version, never will be.

Details and Features:

Let's face it, the Railroad ending is a mess and a huge disappointment. The Institute ending is also disappointing because you have no say in how things are run. So we are changing it up a bit.

Though it's possible to still do a typical boring vanilla run with this mod installed, this mod gives you extra options on how you want to end the vanilla campaign and this includes the ability to:

ignore Father's orders and spare the Railroad, warning them instead and bypassing the "End of the Line" quest

bypass the "Airship Down" quest by speaking to Father again and convincing him to deal with the Brotherhood of Steel by replacing Elder Maxson with a synth double loyal to the Institute instead of destroying the Prydwen, this is only possible if you have previously joined the Brotherhood and met Elder Maxson during the Prydwen introductory quest

if Danse is Elder of the Brotherhood ("Danse Dilemma" mod) you can ask Father to reset him and control the Brotherhood instead of destroying it

if Sarah Lyons is Elder of the Brotherhood ("Project Valkyrie" mod) you can convince Father to not blow up the Prydwen

use Synth Maxson to reinstate yourself into the Brotherhood of Steel faction following your betrayal at Mass Fusion and even promote yourself to the rank of Sentinel

convince Desdemona that taking over the Institute as Director and freeing the synths that way is better than destroying the Institute, this is possible even if you didn't join the Railroad before going to the Institute

regain some level of trust with the Railroad by warning them of the Institute's plan to eliminate them if you didn't join the Railroad before visiting the Institute

have a sit down with the Directorate and reform the Institute, end the kidnappings, grant synths equal rights, this involves finding synth sympathizers among the scientists, having armed backup, persuasion of scientists but also intimidati
