|The following is based on Fallout Shelter or Fallout Shelter Online and some details might contradict canon.|
This quest takes place in a standard, randomized vault. Most of the rooms will contain minor enemies, limited to mole rats and radroaches with the occasional broodmother or irradiated radroach respectively. These are at a comparatively low level considering the requirements, causing minimal danger to the party.
One room contains a major alpha deathclaw which deals extreme amounts of damage, able to one-hit kill even a level 50 dweller all leveled at max endurance in one hit if you're not near maximum health, taking well over half the hit points with each blow. It also has a very large HP pool, even three x5 critical hits will take less than half of it away.
Prepare for a prolonged battle and always double stimpack your direct enemy dweller after each hit is taken. It is therefore advised to bring with you the maximum 25 stimpacks for this quest and dwellers who were fully trained before leveling are preferable.
After finishing the fight you are free to collect the Mr Handy and the lunchbox from the next room and roam the rest of the vault for loot.
