A fallout shelter is designed to allow its occupants to minimize exposure to harmful fallout until radioactivity has decayed to a safer level. Much of this highly radioactive material falls to Earth, subjecting anything within the line of sight to radiation, becoming a significant hazard. The fallout emits alpha and beta particles, as well as gamma rays.

When this material condenses in the rain, it forms dust and light sandy materials that resemble ground pumice. Many such shelters were constructed as civil defense measures during the Cold War.ĭuring a nuclear explosion, matter vaporized in the resulting fireball is exposed to neutrons from the explosion, absorbs them, and becomes radioactive. When a creature is of a higher level than normal, a skull ( ) will appear next to their health bar.A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Dwellers are able to inflict critical damage against creatures found during quests. The further the dweller(s) go into the wasteland, the more dangerous the creatures become.Ĭreatures encountered in quests can be seen, unlike creatures encountered while exploring the wasteland.

If the dweller is too weak for killing the creature and must escape, they still gain ten percent of the score. Killing these creatures gives the exploring dweller experience. They repeat the process until killed or leave after an extended period of time.Ĭreatures can also be encountered by vault dwellers while out exploring, but will not physically be seen in the game. Instead, they transverse to a random room if they are not killed quickly enough in the previous room. Unlike mole rats and radroaches, radscorpions don't multiply. An average dweller level inside that room may also be a factor.Īllowing the intruders to multiply will likely result in the vault's destruction. Mole rats' and radroaches' strength depends on the level of the room in which they spawn. Mole rats and radroaches multiply into adjacent rooms if there are no targets in the infested room(s), or if none enter the room within a short time after they spawn. This can also happen after failing a rush.

General information Creatures attacking the vault Ĭreatures will randomly attack the vault in the form of incidents.
