Super mutant (Project V13)

Super mutants were supposed to be included in Interplay's Fallout MMO, Fallout Online (Also referd to as the original Project V13). From a screenshot as proof of concept one could see what seems like a peaceful super mutant. In The Armageddon Rag Vol. 3's short story On the Beach, the Guardian Brotherhood was fighting against seemingly hostile super mutants.
