what is a beta emitter
The beta wave emitter is a constructible item that was added to Fallout 4 by the Wasteland Workshop add-on. Beta wave emitters are meant to control 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.
