Writing in a blog post today, Bethesda said: “Ever since we shared details about Fallout 76’s Steam launch earlier this year, we have received feedback from PC players in the community who would like to be able to explore Appalachia on both Steam and Bethesda.net. We want you to be able to play on your PC platform of choice. So, we’re happy to announce that if you already own the PC version of Fallout 76 on Bethesda.net, then you will also be able to claim a free copy of the game on Steam for a limited time.”
 
In order to claim Fallout 76 on Steam, you will need to link your Bethesda.net and Steam accounts between now and 11:59PM ET on the 12th of April. The game will have its official launch on Steam on the 14th of April, the same day the Wastelanders update drops. If you buy or claim a Steam copy of Fallout 76 before April 28th, you will also receive Fallout 1, 2 and Tactics for free. The Fallout Classic Collection will also be given as a freebie to those who already own the game on Bethesda.net. Finally, if you want to level/gear up in preparation for Wastelanders, Fallout 76 owners will get Triple XP for playing this coming weekend.
 
I think this is very good of Bethesda to do this. 

I like that they are allowing people to not use their launcher.

I did go and link my accounts, but will I play this game? Probably not, the game has always been complete garbage for me.
