Bethesda game launcher will be shutting down this year, but fear not games will be able to be played on the launcher until May. As well as, the ability to move games over to your Steam library starting in April.
Any games you own on the Bethesda game launcher will show up as free on Steam. Bethesda is saying that you won’t lose anything from your Bethesda account and “Many games will also have their saves migrated, with a few requiring some manual transfers. For games that require it, you will still use your Bethesda.net login to sign in to play.”
Even with the Bethesda game launcher shutting down “Your Bethesda.net account will not be lost and will still be accessible on our website and in-game, and we will continue supporting all Bethesda.net accounts with our future titles,”
Fallout 76 is a game with a bit more questions around it so Bethesda went out of their way to make a FAQ just for it!
