Every year, one of E3's biggest games gets pasted across the towers of The Hotel Figueroa in Los Angeles. We're going to assume that this prime advertising space costs quite a bit of cash to secure, so the fact that Bethesda's nabbed it for Fallout 76 is perhaps an indication that the publisher is going all-in on the supposed spin-off.
Snapped by the ever-informative @Nibellion, The mural itself features three Vault Boys happily striding out of their hole in the ground. What's more, the slogan reads "Our Future Begins". Further indication that this is going to be a multiplayer-focused title? We'll know soon enough when the game shows up at Bethesda's press conference.
