A large atrium complete with tables, a diner and a soccer pitch in the middle. The upstairs levels of the atrium contain accommodation for the residents, complete with beds, color TVs and a wall-mounted Pip-Boy 2000 Mark VI for the player character to acquire as they leave. Several Mister Handies are positioned throughout the vault on the route to the exit and man stations at which the player character can acquire their C.A.M.P. and a few other basic necessities as they prepare to leave. The overseer's office is accessible via going slightly off route while following the trail of equipment stations.
To ensure that all dwellers leave the vault, the vault's main systems, including life support, were to be shut down shortly after Reclamation Day. Unlike other vaults which have a security checkpoint, blast door and elevator to head deeper into the vault, Vault 76 has its blast door level with many of the vault's more critical rooms.
