📋 About This Mod

Deep below the Yangzte memorial lies Vault 121. For more than two centuries it has been a safe haven for the devoutly religious and a veritable playground for the unscrupulous scientists who seek to twist their faith into a means to further their research into human testing and ultimately into an army of genetically enhanced, unquestioning, and ruthless soldiers.

More Details....

This mod adds a new quest that takes you through Vault 121 which is buried close to the Yangzte Memorial. The vault is overrun by Feral Vault Residents thanks to the radiation testing that the vault scientists have been putting the residents through. You will enter into a scene of carnage and have to fight your way through.

The scientists have also been working on some formulas for a genetic enhancement serum that you will ultimately get your hands ( adds new perks ). All of the residents have modified Vault 121 suits, as do the ghouls (new/modified textures). This game also adds the combat shotgun back into game along with a more powerful unique version of it. (w/ modified texture)

Another cool thing is that you will find Vault Soldiers wearing the "Vault 121 Mark I Combat Armor" (New texture for the Reinforced Combat Armor).

Disclaimer...

I haven't found any conflicts with other mods yet, but if there is a mod that alters the area around the Yangzte Memorial, the that will probably conflict.

I made this mod because I love modding, and I hope you all enjoy it.
