Scare Tactics

Scare Tactics is an overseer quest and the final part of The Mystery of Vault 31 multi-stage questline in Fallout Shelter.

Walkthrough
The player's dwellers have acquired ghost costumes and are set on scaring the raiders haunting Vault 31.

The dwellers must fight through the vault, encountering mole rats, radroaches in groups of three to six, feral ghouls in groups of three, and radscorpions. A glowing radscorpion may also be encountered within the radscorpion groups.

Depending on the layout that was generated, the raiders will be found on the third floor or higher. The encounter may be completed without combat if the first dialogue option is selected, by using the ghost outfits to their full potential. All other dialogue options lead to a fight to the death.
