While they possess the imposing musculature and resilience of the former, they have a level of intelligence on par with the dumber examples of the latter. The super mutants of the Commonwealth are a different strain from Vault 87 super mutants and those created at Mariposa. if there is a god, may he have mercy on us all. Everything that we've done, the lives we've taken. Somewhere not even the Coursers can find me. After that.I know what I'm about to do will be seen as a betrayal.

Similarly, in Nuka-World, small bands of mutants can occasionally be found roaming the plains and foothills surrounding the amusement park, though they tend to stay outside its walls. In Far Harbor, a group of super mutants have traveled to the Island and are located in the Vim! Pop factory, National Park HQ and Aldersea Day Spa. They are most frequently encountered in central Boston, and can also be found in Fallon's department store, Fort Strong, Trinity Tower, Revere satellite array, Big John's Salvage, The Gwinnett Restaurant and several other locations all throughout the Commonwealth, most of which can be identified by the telltale signs of hanging meat bags, twisted girders protruding out of the ground, cages and gory waste piles with which they enjoy decorating their surroundings. They are large, muscle-bound creatures with innate immunity to radiation and disease. These mutants were created by the Institute by means of exposure to the Forced Evolutionary Virus (FEV). Institute super mutants are the variant of super mutant found throughout the Commonwealth, Nuka-World and the Island in 2287.
