The Fallout 76 B.E.T.A. test was just held on Xbox One this week (you can check out our extensive thoughts on it here), and we used the four-hour window to capture some gameplay that might help you understand what's going on, including the crafting system.
This isn't a million miles away from what it was in Fallout 4, but the video below shows you the in-game tutorial, running you through the basics of crafting armour and weapons, modifying them, and getting scrap to use in these ventures.
Do you like the look of the crafting?
