📋 About This Mod
"Fallout 4 is definitely not worth beating twice".
- Forbes magazinepkXGaYFTzkMThank you Nexus for voting Project Valkyrie Mod of the Month for August 2018.
Mod Overview
- Twenty quests, with a story that lets you finish the vanilla game in new ways. Want to imprison Preston and execute Desdemona while brokering peace between the Institute and the Brotherhood? Kill everyone? Let the four major factions co-exist in harmony? Or something in between? Now you can. Here's a detailed example of what's possible.
- Four custom and fully-voiced companions to choose from, plus seven vanilla-based companions (details below). You meet each companion in the course of the adventure as you progress through the mod's main quest line.
- As Director of the Institute, you can actually direct the place: free the synths, kick out the bad guys, do new types of missions, give the building a new look, add vendors, new areas, and open the place up for trading with the Commonwealth.
- Challenge Elder Maxson for control of the Brotherhood of Steel and take Liberty Prime along as a follower to spread murder and democracy throughout the Commonwealth.
- Convince Desdemona to chill out. You're the Director of the Institute now. You can free the synths. No need to turn Cambridge into a crater.
- Use persuasion instead of violence to resolve disputes between factions (or vice versa), choosing who lives and who dies.
- A hopefully more engaging approach to the fate of Sarah Lyons and the other BoS main characters from Fallout 3 instead of a single, unsubstantiated terminal entry that she "fell in battle", with no further explanation.

The mod works regardless of what point in the game you're at or which factions you've sided with. You can play on a new save or any existing save. However, if you want to play 100% of the content, the Prydwen and Institute will need to be intact. If both the Prydwen and Institute are ashes, two of the main quests will be an hour shorter.
Required Files and Installation
Outcasts and Remnants version 1. 5 or higher is required. The game will not load if Project Valkyrie is installed without Outcasts and Remnants, and most of the content won't work unless you have at least v1. 2 of Outcasts and Remnants (i.e. if you're running v1. 1 or earlier, update to the latest version).
If you've completed the quest "Heir to the Throne", and the next quest, "Wag the Dog", doesn't start, it's beca
