Theirs was the "No posibility of getting out"... and like all the others, it failed. They were given everything they needed in the vault OTHER than a G.E.C.K. that would allow them to live outside. In the first game, they had a defective water chip and no replacements and no G.E.C.K. - they were given a real reason to send someone out and try and make it without the vault or tech to back them up. There was another one that had everything - Vault City in F2. They just turned into a city full of elitist snobs.
