InFAMOUS Second Son

Infamous Second Son is an open-world action-adventure video game that follows the story of Delsin Rowe, as he attempts to save the people in his home town. The player can choose whether Delsin will "save the day", or be completely evil. The game has a morality gauge, labelled your "Karma Rank", which is increased through good deeds or bad deeds (depending on your path).
