Fallout 76 official teaser trailer
The trailer begins with a closeup of a Pip-Boy 2000 Mark VI as it turns on and begins playing "Take Me Home, Country Roads," performed by Spank Live and written by Bill Danoff, Taffy Nivert and John Denver. As the camera pans out, it is revealed that the Pip-Boy is set to 6:34 AM on October 27, 2102, and a Vault 76 bedroom is shown. A television shows a conference held outside of Vault 76 before the Great War, explaining the need of the vault to help rebuild after the War. The atrium of Vault 76 is filled with party favors celebrating Reclamation Day. A man in a Vault 76 jumpsuit puts on the Pip-Boy as the narrator states "In Vault 76, our future begins."

Live Action trailer
Another trailer, featuring real-life actors portraying scenes and locations from the game, was released on October 28, 2018. It opens with a shot of a mega sloth as the Beach Boys' song "Wouldn't It Be Nice" plays. The camera pans over to a young woman spinning around, firing dual wield submachine guns at feral ghouls and Protectrons. The next scene takes place at Mount Blair, with two men in power armor fighting off a wave of Liberators. It then cuts to a shot of a frog in the Cranberry Bog looking at a group of four explorers. A C.A.M.P. set up around a Red Rocket station is shown, followed by three people sitting around the campfire, roasting marshmellows with a deathclaw and Mister Handy. Another scene in the Cranberry Bog follows, with a woman holding a laser rifle meeting another unseen person. The final shot brings all of the characters together to watch a nuclear explosion, from which a scorchbeast rises.

Vault 76 animated teaching shorts
Vault-Tec would produce several animated short films - the same animation style as the What makes you S.P.E.C.I.A.L. shorts - exclusive for Vault 76. These films would focus on the unique position and equipment Vault 76 would be in and have when emerging in 2102. Each of the films prominently feature Vault Boy either succeeding or failing as an illustrative lesson on the do's and don'ts of Appalachia, often with cartoonish gorey results.
