NOTE: Make sure the first time you level up, you take the Science Perk at Level 1. Bottle Caps act as money in the world of Fallout 4 and the best way to make money in the game is all around your first settlement in Sanctuary, the river and lake but more on that in a moment.Īfter you help Codsworth rid the neighborhood of a few pesky Bloat Flies, your main focus should be set on scrapping everything in the neighborhood.
