Scrap items will bump up your carry weight a little bit, and cause you to become overencumbered if you have too much. All items of the old world that don’t serve a purpose anymore. This includes things like desk fans, duct tape, toasters, cameras, and much more.
This is essentially any kind of item you pick up in Fallout 76 that isn’t a weapon, piece of equipment, consumable or otherwise. Junk functions much like it does in any other Fallout game, and you’re going to come across a lot of it during your time. Part of the main hook of any Fallout game is scavenging the various abandoned buildings and wrecks, grabbing all the pieces of scrap and junk that you can. Life in the wasteland is never easy, that’s as true in Fallout 76 as it was in Fallout 3 and 4.
