To conclude, build and power 5 cages of the same type of normally hostile creatures. 5 deathclaws, because different animals are still hostile to one another even in the presence of beta wave emitters. I would also recommend taming 5 of the same creatures, e.g. NOTE: This achievement requires normally hostile creatures so domestic animals will not work, such as house cats, dogs or gorillas. To make this easier do not wire the cage and the beta wave emitter to the same power source otherwise the creature will be released and become hostile because the beta wave emitter was switched off at the same time as the cage.

It will take several seconds of remaining docile outside of the cage's confines (they do not spawn into the settlement until the closed cage is opened by shutting off the power) for the creature to count as 'tamed.' Creatures are counted as 'tamed' by releasing a trapped creature, in the presence of a beta wave emitter. For this achievement, you need 5 Tamed creatures in a settlement at the same time.
