These locusts, known as the eighth plague in biblical terms, are genetically engineered mutants designed to consume other crop pests. Unfortunately, a secret military black budget project manipulated the experiment for a military purpose — a biological superweapon against all life.
Mutant locusts are actually fueled by pesticides. They are extremely bloodthirsty and will strip a living being to bloody bones in seconds. Although they were genetically manipulated so that they would die after just a few days, the locusts have proven capable of breeding, which makes them extremely difficult to exterminate. They create nests in large caverns, spinning giant coccoons that are unusual for locusts.
