"In MUTANT MONSTER MACHINE GIRLS, you play as a member of "The Girls", a group of queer misfits fighting against an oppressive anarcho-capitalist state ruled by The Corporation.
Each of you fights against them because all your lives have been ruined by The Man Responsible, a dangerous and cruel servant of The Corporation. Because of his actions and the nature of your evolutions, you can no longer return to your previous lives and the people you love.
Your only solution? Exact your ultraviolent revenge on him and bring peace to the city by force!"
