You play from the perspective of Zoe, an 18 year old university student at home for the summer. Under the influence of a friendly if not rather pushy alien parasite, she embarks on a lust-filled quest to corrupt and infest the members of her immediate family. As the player, you will get to steer Zoe through her quest, helping her find ways to seduce those close to her, set up a harmonious and efficient breeding machine, and dominate the home, the street, the city and then, who knows … maybe the world?
