In Fallout 76, Caps serve as the primary currency for trading. They are widely accepted by standard vendors and players throughout the post-War United States, including Appalachia. Caps can be obtained through various methods, such as finding caps stashes, completing quests, and even drinking a refreshing Nuka-Cola2. These bottle caps are essential for acquiring goods, services, and other valuable items in the game world. So, whether you’re bartering with vendors or fellow survivors, Caps are your go-to currency!
