Evolutionary Experimentation Program

Evolutionary Experimentation Program (EEP) is the experiment run in Vault 87 to create improved soldiers. Subjects were reported as an "unknown death" and then exposed to a modified FEV virus. After exposure, the subjects undergo physical and mental changes. Their form becomes asexual and muscular, however their mental facilities diminished and they became overly aggressive. They became the Super Mutants found on the East Coast. The mutants found in Vault 87 mention that they capture humans and dunk them in the green stuff to make more Super Mutants, continuing the program.
