Project Valkyrie is a game mod for the popular video game Fallout 4. It is a fan-made modification for the game using the game engine, not the actual game of Fallout. It is an expansion and, like all other fan-made projects, will work on any version of the game it was designed for. Unlike many other mods, this one has actually been produced by someone with experience in the game's creation, namely Obsidian. It features a number of features that are sure to excite and please the fan-created fans of the game and also includes some unique content not seen anywhere else.

Here is what the Project Valkyrie mod adds in the long-awaited follow-up to the vanilla game. As with all of the great things about the vanilla game, this mod is free and will add many new items and areas to the game, such as a new quest line focusing on a group of Vertigo survivors who are stranded in a post-apocalyptic bunker after a nuclear war. The mod features an interesting plot and gives you a lot more information about your favorite characters, such as the character of Harkins, who was left as a slave and became a master breeder of Vigors. Other areas include a power armor trainer, an ammo store, and a bunker, making this a very customizable game.

One thing that sets this mod apart from the other similar mods is that it adds four new companions to the game: Doctor Perkins, Arbiter, Bishop, and Stompin. All four companions have their own unique voice packs so you can customize them as you wish. In addition to having a companion, Project Valkyrie lets you use a unique skill tree instead of using the vanilla one, giving players a bigger choice when developing their character. This is definitely a more fun experience than just having to fight through the same quests over again.
