A new Fallout title that’s not a mainline title in the series, and a teaser that provides very little info. A rumor is that the title will feature an online component, multiplayer, a renewed focus on the settlement building mechanic from Fallout 4. It’s even been called a Fallout themed Rust (an online player-versus-player survival video game) clone, according to some sources.
Of course, we’ll have to wait until this year’s E3 to see how much of these rumors are true.
