By Hook or by Cook

By Hook or by Cook is an overseer quest and the final part of the Food, Glowrious Food multistage questline in Fallout Shelter.

Walkthrough
The vault dwellers travel to a one-room Red Rocket to confront the Cook and two members of the Cook's gang, who all wear white officer outfits, presumably because of the resemblance to a chef's uniform in real life.

After a brief exchange of dialogue, Cook's group becomes hostile. The Cook will turn out to be a raider boss, as indicated by a skull beside the health bar. They will be armed with a flamethrower, butcher knife, and kitchen knife.

A Commander uniform will be awarded at the end of the fight. A butcher knife, as well as a random junk, can be looted from the room.

Behind the scenes
The title of this quest is a reference to the centuries-old saying, "by hook or by crook," meaning "by any means necessary."
