It's not much, but you can probably bet we'll get more details during tonight's Bethesda press conference, starting 1130 AEST today.
"Fallout Shelter" is a free-to-play sim game where you build a vault, fill it with dwellers, and go on quests in the Wasteland. Weapons appear more dated than previous Fallout games, as a gameplay sequence featured a single-shot pistol, complete with the player having to refill the gunpowder after every round.
We already saw the Fallout 76 teaser during Microsoft's presser, but now Bethesda has announced that the game has online multiplayer - it's a sort-of MMO. Tell us in the comments.
Then they rolled the trailer and we got to see the Vault 76 in action. Previously, Fallout Shelter was available on iOS and Android, Xbox One, and PC. There'll be six distinct regions across the expansive world - some four times the size of the one found in Fallout 4 - and within that world you'll also find a number of nuclear missile sites that anyone can access.
A closed beta is available to players who pre-order the game after June 15, as Bethesda stress-test the servers before a wider release. Or, solo. Online functionality works in a similar fashion to Sea of Thieves, instanced with limited players and the ability to group with friends.
Fallout is going online with Fallout: 76.
You'll find yourself in West Virginia in 2102, with a vast wasteland to conquer, and a wide array of monsters and other threats to contend with. Drop $0.76 into the Mement-o-Matic coin machine to receive a special Fallout 76-stamped commemorative penny.
Like previous Fallout collector's editions, it's not cheap. Be the talk of the town when you emerge from Vault 76 fully prepared and patriotically styled in the new American frontier! "That's right, one of the many things players will be able to do in Fallout 76 is discover nuclear launch codes and use them to decimate their enemies" strongholds.
