Hot Tub Slime Machine

Hot Tub Slime Machine is a single stage overseer quest in Fallout Shelter.

Walkthrough
This quest takes place in Vault 189, which will be generated with a random layout. The dwellers will mostly face feral ghouls in groups of three to five, but will also likely face mole rats in groups of two to three, and radroaches in groups of three. Further in there will be glowing feral ghouls that are accompanied by four additional feral ghouls. One of the glowing ghouls will yield three Nuka-Cola Quantums on its corpse, and the room it is in contains a legendary weapon recipe. Near the bottom of the vault is a dweller who will give the dwellers a lunchbox, and the room they are in contains a legendary junk item and a rare weapon.

Behind the scenes
This quest's name is a reference to the 2010 comedy movie Hot Tub Time Machine.
