The beta wave emitter is a constructible item that was added to Fallout 4 by the Wasteland Workshop add-on.


Beta wave emitters capable of pacifying normally hostile wasteland creatures and animals captured in cages. Any released creature under the influence of an active emitter will refrain from attacking the Sole Survivor, their companions, and any resident settlers, however they can still occasionally attack other tamed creatures that are not of their own species. Any survivors will then prowl the area and defend it against outside aggressors, adding a race-specific value to the settlement's defense rating without taking up a settler slot. The creatures can therefore be used as a mobile defense force of varying power.

It is important to note that hosting captured non-domesticated creatures of any kind in a settlement will make that settlement the target of regular attacks by other members of the captured species or faction.

A beta wave emitter requires 1 unit of power to work, and is effective throughout the settlement in which it was built.

Creature defense ratings

These numbers are independent from the respective creatures' subtypes; a mythic deathclaw adds the same value to a settlement's defense rating as a standard deathclaw, but will of course be much more powerful in actual combat.

Radstag variants "yearling" and "doe" give no defense rating, however, "standard", "albino", "rabid", and "glowing" variants add 2 defense.

Note that these values' comparability to those of turrets is somewhat debatable. A heavy laser turret for instance provides a defense rating of 12 but will have serious trouble with taking down most mid to high-level attackers on its own, especially during the later game stages. A powerful levelled deathclaw variant on the other hand can wipe out an entire raiding party of the same level single-handedly, despite boasting a lower defense rating than the turret. Conversely, creatures such mutant hounds and even most mirelurks usually will not make it very far despite their good ratings.


  • Tamed creatures are still susceptible to Animal Friend or Wasteland Whisperer pacification attempts. Doing so is almost guaranteed to succeed but will not give the player actual control over the creature regardless of perk level. The pacified creature will turn hostile as soon as the Sole Survivor holsters their weapon, however, thus making it ill-advised to use any of those perks on already tamed creatures.
  • In addition, taming a creature will only affect the relationship between a creature, settlement members, the Sole Survivor and any companion. It will not make a creature friendly towards creatures of a different kind which it is ordinarily hostile - even if both creatures are tamed (e.g. a radstag doe will attack any insect until one of the insects kills it; a yao guai will eliminate all radstag does).
  • All tamed creatures will become hostile towards the player and their companions/settlers should the emitter be turned off. For the same reason.
  • Captured Gunners, raiders and super mutants are not affected by this device, and will attack the player, settlers, robots, or companions on sight when released from their respective cages.
