The squad confronts a homegrown terrorist threat from a previously unknown group of mutant supremacists. Can they learn the truth behind the Mutant Revolutionary Front – one that remains shrouded even from its own suicidally indoctrinated followers? Content Warning: terrorism, suicide. In Mutant City Blues, players take on the roles of super-powered police officers solving crimes committed by or against other mutants. MCB scenarios blend a street-scaled take on the supers genre with the mood and tropes of television cop shows.
