I watched the qore preview once again and when the think tank called dr. mobius is talking to you in the background there is a sliding vault door and what looks like an atrium. I wonder if the facility has a vault. Thoughts?

Would be awesome if the DLC had a vault. But we shouldn't expect any one alive down there. Atleast not normal Vault Dwellers.

Would explain the plethera of Lobotomites if there was a vault with dwellers. Though another likely explanation is they've hired thousands before to help.

Either the Vault is protected by robots, or the Vault houses those Lobotomites.

As stated on the previous thread the presence of Repconn, H&H Tools, and RobCo, give strong credence to the possibility of Poseidon Energy, General Atomics, Vault-Tec, and any other major Robotics/Science/Weapon companies i forgot, all having labs in the Big Empty.

My guess is the vault is a headquarters for the think tanks and it's also where they perform their experiments
