Fallout 76 got a glamorous close-up at the Xbox E3 2018 keynote this afternoon in Los Angeles. Todd Howard of Bethesda Game Studios promised the game would be “four times bigger” than 2015’s Fallout 4, and will be set in the Appalachian Mountains of West Virginia, 20 years after the devastating nuclear strike that created post-apocalyptic landscape of the Fallout canon.

Fallout 76 was announced by Bethesda Softworks earlier this month. Howard called it the series prequel. In the game, players will emerge from Vault 76 in the Shenandoah Valley, tasked with rebuilding society a quarter-century after nuclear weapons have devastated the land.

Much more on Fallout 76 is expected from Bethesda’s own E3 keynote later this evening. The game is expected to have a heavy multiplayer component, unlike the other Fallout games since Bethesda took custody of the single-player RPG series, beginning with 2008’s Fallout 3.

Additionally, Howard announced that Fallout 4 would join the Xbox Game Pass subscription service. “We’ve had an incredible 16-year history with Xbox going back to Morrowind,” he said, referencing the 2002 classic from The Elder Scrolls series.

Bethesda’s E3 2018 keynote will begin at 6:30 p.m. ET. Fallout 76 and Rage 2 are expected to highlight the publisher’s announcements. Fallout 76 doesn’t yet have a launch date. Here’s everything we know about its story so far.
