Users will start a new adventure entirely separate from the main game. The scale of this project is closer to an expansion or DLC. We currently have many excited team members working on this project to the bring the Pacific Northwest to the world of Fallout. Inside the mod, players will find new quests that challenge them mentally and morally, locations that tell a story, and factions that are vying for control. Release Date TBA"
