Bethesda’s Creation Club service, which the company announced at this year’s E3, is now available in Fallout 4, letting players buy new weapons, armor and gear for the 2015 game.

Creation Club offers a collection of “new official content” developed by Bethesda and its development partners that players can purchase with credits (which can in turn be purchased with real-world money). Creation Club content differs from gameplay mods, which are typically created by fans, by being “fully curated and compatible with the main game, official add-ons, and achievements,” Bethesda says.
