From Bethesda itself as well as third parties
Bethesda is breathing life into some old classics in the form of Creation Club, a “collection of new game content for Skyrim and Fallout 4” that includes new weapons, armor, accessories and other things made by both Bethesda employees and outside creators. It’s all totally sanctioned by Bethesda so it will definitely work with your game — whereas mods can cause some problems with existing save data and things like that.
Creation Club is coming this summer to PS4, Xbox One, and PC.
