Fallout 76’s titular vault will open Nov. 14, 2018, publisher Bethesda Softworks announced today during its BE3 Showcase ahead of E3 2018.

Bethesda Game Studios game director Todd Howard said the company will conduct a beta for Fallout 76 — it’s an online multiplayer game — although he did not give a time window or platforms for the beta. The beta will be “run” by Vault-Tec, the company that constructed the vaults in Fallout’s fiction, as the “Break-it Early Test Application.”
