Not so with Fallout 76.
Bethesda's online action role-playing game "Fallout 76" won't be available on Valve's Steam platform during beta or when it launches on November 14. In an FAQ, Bethesda noted that their plan for the upcoming test period will be to include the full game. A small taster to test online servers or game balancing.
Bethesda's first attempt at an online game (the developer, not the publisher who has released Elder Scrolls Online) will likely be a rough one given their track record with single player games.
Now the only way to get access to the beta is by pre-ordering Fallout 76, which you can do so from the Microsoft Store here.More news: West Nile-infected mosquitoes found in Wyoming

The change won't make much difference to anyone playing the game, other than being yet another new thing you'll have to sign up to and forget the password for. That's not to say it won't happen eventually, but it may be quite a wait if it happens at all-Fallout Shelter was released on Bethesda.net in July 2016, but didn't make it to Steam until March 2017. "We hope you join us!"
Obviously, none of this affects the Xbox One or PlayStation 4 versions.
When it comes to the PC version, Fallout 76 won't be available to buy on Steam, with Bethesda deciding to directly sell the game itself instead.
The BETA will start some time in October, so you've not got long until you jump into the biggest Fallout world yet. As PCGamer points out though, it took nearly a year for that to happen with the mobile-orientated game, so it could be that it takes some time for Fallout 76 to make the jump, if it ever does.
