Vault 77

Vault 77 is one of the Vaults created by Vault-Tec, and part of the Vault Experiment. Only one man entered this Vault, which also contained a crate of puppets, labeled "P13X U.S. GOVERNMENT ISSUE PUPPET RATION". The location of this vault is unknown.

Background
During the first months, the Vault 77 Dweller went through the initial panic and depression caused by being locked alone in a Vault while the world ended outside. He didn't actually open the puppet crate until one year, three months and twelve days after the lock-up.

After opening the crate, he takes particular interest in a dog puppet (which he named Reverend Hound, and also decided to make Sheriff), a king puppet, and a grandmother puppet.

These puppets appear to give him something to do and keep him company for a while, until he finds a Vault Boy puppet in the crate that he'd missed earlier. This puppet seems to have a mind of its own and to speak directly to the Vault 77 Dweller, which the other puppets do not; it is never specified if it truly does possess its own (evil) consciousness, or if this is just a symptom of the Dweller's further descent into insanity. One night, the king puppet is found "dead"; when the Vault 77 Dweller confronts the most likely suspect, the Vault Boy puppet tells him that in fact they did it together and must flee before Reverend Hound comes for them.

The Dweller opens the Vault door, only to find a gigantic radscorpion holding up a car in each claw. The Dweller decides they should sleep on the plan. Later, he somehow manages to leave the Vault, befriending a giant ant which he takes as a mount.

Some time after sharing a campfire meal with an unnamed but civil Ghoul (possibly from Necropolis, as he also wears the tatters of a Vault suit and hints he originally came from a Vault), he is captured by slavers who are uncertain whether to make him a slave or just eat him. The Dweller tries to warn them not to hang around him as his puppet is an insane killer. Later that night, the threat becomes a reality as the slaver home camp is razed, with the Vault 77 Dweller standing amid the carnage afterwards, both he and the puppet covered in blood.

The comic ends with a conclusion that Vault 77 didn't turn out so good but reminds the reader that "the Vaults were never meant to save anyone."

This vault has a very interesting setting. Like any other known vault it had a vault experiment. The vaults weren't infact never meant to save anyone, but test several experiments on human subjects. Many of these experiments were crazy and inhumane, like releasing psychoactive drugs into the air (see Vault 106). As in the vault 77 case, Vault-tec where obviously testing how long a man's psychic could last if he was alone with toys knowing that the world where destroyed above him. Eventually, the experiment was a success.
