Not every failed human experiment is disintegrated in the process or reduced to a sentient mass of quivering flesh. Some failed experiments grow bestial, monstrous, and highly effective at causing destruction among the enemy ranks. Like faithful canines, these failed experiments are given simple commands and sent howling at the foes of the Crucible Guard where they will cause unimaginable havoc. Whether they live or die in the process is irrelevant, as this secondary experiment is almost always a smashing success.
