...and he came back.

I like this comic pretty much. And I really enjoy when game developers gives us little references in games. Since I wish in next fallout game there will be more information about other vaults.

"Vault 77 appears only in the official Fallout webcomic One Man, and a Crate of Puppets. The purpose of Vault 77 in the vault experiments was to be populated by only one man and a crate full of puppets.
A Vault 77 jumpsuit can be found in Paradise Falls in Fallout 3, alongside an audio recording of an obviously worried slaver, saying how it scares the others and it should be burnt, and that "he" may be back for it. The slavers obviously fear "him", hinting that it may belong to the vault dweller who killed the slavers who captured him". (c) Fallout wikia

Audio recording:
"Like I told you man. I don't fucking know where it came from. But it freaks the boys out. Some story from a while back, 'bout a stranger with no name.
Just...get rid of the damn thing. Ain't no good gonna come from keeping it around. Besides, if it is.. his. Maybe he'll come back for it. Comprende?"
