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.
