And by Steamy we mean that the publisher has announced that it's upcoming games, in addition to Fallout 76, will be making a return to the Steam storefront and ecosystem. The announcement made via a Tweet specifically calls out it's upcoming list of titles including RAGE 2, Wolfenstein: Youngblood, Wolfenstein: Cyberpilot, and DOOM Eternal - all coming to Steam.
Which means that all new Bethesda releases won't be exclusive to the Bethesda Launcher on PC. And of course, the announcement wins a few extra points for being the first bit of news like this in a while that isn't all about Epic Games Store exclusivity.
In terms of Fallout 76, there's no word yet on whether accounts or copies will be transferable. When brought up by a member of the community the response at this stage points to this not happening - with Steam and the Bethesda Launcher being two separate platforms.
