Following a 24-hour livestream on Twitch, Bethesda Softworks unveiled the next game set in the Fallout universe. It’s called Fallout 76, which refers to the vault where it takes place.

The teaser trailer, embedded above, includes scenes set inside a relatively well-maintained fallout shelter. The vault looks decked out for a party, with balloons and confetti all over. A sign says that the occasion is called “Reclamation Day.” A Pip-Boy makes an appearance during the teaser, but there’s a conspicuous lack of weapons of any kind. The entire setting looks extremely domestic, set inside a child’s bedroom and a family living space.

The only character shown on screen is a single vault dweller, donning a blue Vault 76 suit and wearing a Pip-Boy with a date that reads Oct. 27, 2102. A broadcast in the trailer features an official saying, “When the fighting has stopped and the fallout has settled, you must rebuild.”

The teaser trailer’s musical score is a cover of John Denver’s 1971 hit “Take Me Home, Country Roads,” which could indicate that Fallout 76 takes place in the state of West Virginia. Files on Bethesda’s press site appear to refer to the game by the codename “Mountain,” which could also be a hint that the game will take place in or near the Appalachian Mountains.

Kotaku reported that Fallout 76 will be “an online game of some sort.” Polygon has also heard the game will feature multiplayer.

A press release sent out by Bethesda said Fallout 76 is in development at Bethesda Game Studios on PlayStation 4, Windows PC and Xbox One. We expect to learn more during this year’s E3 in Los Angeles. Bethesda has its own press conference, called BE3, scheduled for Sunday, June 10, at 6:30 p.m. PT. It’s the publisher’s fourth dedicated E3 event.
