Bethesda's Todd Howard stopped by the Microsoft E3 press conference to show off a new trailer for the upcoming Fallout 76, but that wasn't the only surprise. He also announced that Fallout 4, the hit open world action-RPG, would be added to the Xbox subscription service Game Pass. It's available today.

Fallout 4 was a critical hit according to GameSpot sister site Metacritic. It's had free weekends but on GamePass, it will remain playable with the subscription for the foreseeable future. Game Pass is a $10 subscription that gives players access to a wide array of all-you-can-eat Xbox One and Xbox 360 games, including all first-party titles.
