We've all heard rumors of a bottomless Vault, one that is deeper than any others that have been built, but now it seems we may have actually located it! We need to send a recon party to explore the Vault and unlock its deadly secret.

The Abyss is a single-stage overseer quest in Fallout Shelter.

Walkthrough[]

This quest has one of the largest numbers of rooms. It has feral ghouls, radroaches, radscorpions, mole rats, and deathclaws as enemies. The deadliest enemies here is an alpha deathclaw with a regular deathclaw and an irradiated radscorpion with two regular radscorpions.

Notable quotes[]

  • "Abandon all hope, ye who enter here..."
  • "How deep does this actually go?"
  • "I'm staring into the abyss, but nothing's staring back."

Dialogue[]

Opening dialogue Dweller response Character response
Oh, hello, I hadn't seen you there.

We don't get many visitors down here, with all the critters and whatnot.
It only gets worse as you go deeper, or so my brother tells me.
He lives near the bottom, where it's cool and quiet.

So, there *is* a bottom, then? Sure. I think. I've never been myself, but there *has* to be one, right?
What can you tell us about this place? You should ask my brother, he used to be the Overseer of this Vault.
How much further down is your brother's place? Look for Deathclaws being too afraid to chase you deeper.
My eyes must be deceiving me...

No one has come this deep in decades...
Even then, very few people ever did. Robots built most of this Vault.
They malfunctioned, and just kept on digging until they broke down.

This is the bottom then? More or less. Some robots continued to dig a bit more.
Why do you stay here? I like the peace and quiet. It's pretty safe down here, you know?
So, this is the result of malfunctioning robots?! Yup. That was our experiment, to have robots do all of the manual work.
I think your brother misses you. Yeah, I haven't seen him in a while. Maybe I'll visit him in the Spring.
