For me, the fundamental aesthetic challenge in creating the Supermutants was this: how do you make an oversized, musclebound green man NOT look like The Incredible Hulk? The Concept Artist Adam Adamowicz - who passed away not 6 months after he designed the look of the redesigned Supermutants (he’d also concepted the ones from Fallout 3) - came up with a great aesthetic which I carried through into the final 3D model. He imagined barrel-chested men, lanky, hairless and warted... men whose muscles hung like cow fat, and whose green skin folded and ran like warm taffy... So this is what I made.
