Cabin Fever

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

Walkthrough
Possible enemies in the first room include radroaches, two feral ghouls or a single deathclaw, depending on your dweller's level. When you come across the dialogue options from the raiders, you can have your dweller pretend to not see or hear them to avoid a fight. You are rewarded with rare loot whether you fight them or not.
