Infested!

Infested! is a random encounter in Fallout Shelter. It can be triggered by any dweller who is exploring the wasteland.

Walkthrough
This is a rather simple encounter started by finding an abandoned cabin in the wasteland. Inside is a woman who has claimed the location as her home, though she has an issue with radroaches infesting her basement. The dweller will agree to help her with the problem in exchange for taking items out of the basement as a reward. The basement will have a small number of radroaches, led by a glowing radroach. Eliminate them and take the treasures from the cabin.
