Bethesda Softworks announced the latest in the Fallout series this morning, Fallout 76. While most fans assumed the game would be a single-player entry like its predecessors, rumors circling the title point to it being focused entirely on multiplayer.

Three anonymous sources (via Kotaku) familiar with the project claim the game is an online survival RPG, much like DayZ and Rust, and that the game had started originally as a prototype for a multiplayer version of Fallout 4. As the game is set in the fictional Vault 76, which started with a large human population before the nukes dropped, it makes sense multiplayer is a focus.

Reportedly, the game has changed a lot in the past few years, but will have staples of the franchise like quests and a main story. There will also be base-building, like what you’ve seen in Fallout 4. There will also be other survival and multiplayer mechanics, however one of the sources warned that gameplay, like in other online or “service” sandbox RPGs, is changing quickly.

That’s all we have to go on with this rumor, however it’s worth pointing out the reveal teaser trailer does note that “when the fighting is stopped, and the fallout has settled, you must rebuild.”

The full reveal for the game, which is set for a PC, PS4, and Xbox One release, is set for the company’s showcase at this year’s Electronic Entertainment Expo, on June 10th.
