|The following is based on Fallout Shelter or Fallout Shelter Online and some details might contradict canon.|
The first enemy you come across is a mole rat broodmother and a regular mole rat. The next room has four mole rats. In the room to the right is a pair of feral ghouls. If you take the elevator down, there is another broodmother plus regular mole rat pair. To the left of that is another pair of mole rats, and in the room to the very left is a pair of ghouls.
If you take the elevator back up, there is a group of three mole rats before the next elevator shaft. The next floor has a pair of feral ghouls, and in the room to the right, is the glowing ghoul accompanied by two additional feral ghouls. Defeat the glowing ghoul group to receive a random legendary junk, and an objective completion. The next floor up has two pairs of ghouls, and the room to the left of these two has three ghouls. This room contains a legendary weapon recipe.
If you take the elevator down, you'll come across a pair of mole rats, and a pair of ghouls. The top floor has another pair of ghouls, and the room to the right of that is some civil ghouls who you can speak to for an optional fight and the last quest objective. The first dialogue option is the most diplomatic, the second guarantees a fight, and the third is a neutral response.

|What do you want, Dwellers?|
There is nothing of value in this place, only junk.
|We're just here to clean the gray goo off the machinery.||Really? Thanks! We were wondering how to get rid of it. We even tried this!|
|Not before we get what we came for.||All right, have it your way!|
|Our chef wants us to bring back processed cheese, and we will.||You guys actually eat that? We could kill you, but this actually sounds worse...|
