Game: Fallout3 Mod Name: Vault 691 Version: 1. 4 ESM Author: Necroflange Release Date: 11-16-2013 Category: Adventure and Quests ---------------------------------------- Description: ========== This is my first mod release... So be kind. Also, I\'m not a super computer geek so don\'t expect a lot of high tech anwsers if things go wrong... But I have a few friends... That being said... Deep under the Dunwich Building, a group of scientists from the Commonwealth found an old private corporate vault (Dunwich Borers, LLC) to use as a headquarters to study the effects of ghoulification on the Dunwich Ghouls... Some how things went terribly wrong. The main quest leads the player deep into the Dunwich Sewers (a vast network of long abandoned sewer lines), in search of the surviving members of the science team, so he/she can find the key to unlock vault 691. Sucessful completion gives you a vault type player home near dunwich. The main quest starts in the parking lot of the Dunwich Building.. A note found on a dead doctor triggers the quest.. This mod offers: ============ -2 quests -Fully voiced and lipped NPCs -A Player home -Personal vendor -5 retextured outfits -2 new melee weapon meshes.....a machete and a Kukri -2 custom Jukeboxes, with original music from the first 2 bands I was in. -A few new static meshes from some other projects I\'m currently working on. -Hours of fun and adventure!
