While Bethesda has decided that Fallout 76 won’t be gracing Steam with its presence – instead being delivered directly to gamers via Bethesda.net – the firm has clarified that this doesn’t mean it’s abandoning Valve’s online games store completely.

Pete Hines, senior vice president of global marketing at Bethesda, clarified to IGN: “We did not announce ‘all future Bethesda games will not be on Steam.’ That is not what we said. We said ‘this game will be available exclusively on Bethesda.net.’”
