Incidents are a game mechanic in Fallout Shelter.
Characteristics[]
Incidents can happen randomly, or when the rushing of a room fails. Incidents need to be dealt with quickly by dwellers or they will spread to adjacent rooms. During an incident, dwellers in the same room are damaged and will not produce anything until the incident has been resolved. Possible incidents include radroach, mole rat and radscorpion infestations, fires, and raider, feral ghoul, alien, or deathclaw attacks.
Notes[]
- Mole rat incidents will start in rooms touching dirt, including the "stone" on the edge of the build area.
- External attacks cannot be caused by failing to rush a room.
- The difficulty of the incident depends on the size and the level of the room it starts in.
- Raider attacks start appearing at a vault population of 14+.
- Feral ghoul attacks start appearing at a vault population of 40+.
- Radscorpion attacks start appearing at a vault population of 50+.
- Deathclaw attacks start appearing when the vault has 60+ dwellers.
- External attacks will often occur immediately after sending a dweller to the wasteland.
