Fallout 76 will do something rare for a PC game: It’s skipping Steam — at least at launch — and will only be available from publisher Bethesda Softworks’ own launcher. According to Bethesda’s senior vice president of marketing and communications, Pete Hines, that’s so the publisher can bypass the middleman and work more directly with players.

“In this particular case, it’s an online game and we felt like when it comes to the PC that being able to directly serve our customers,” Hines said, “and having that one-to-one relationship was hugely important and key to us being able to do the best game possible.”
