About Patent9
Patent9 is a noir sci-fi mystery visual novel set in a neon-lit, rain-soaked deco city. You follow Lang, a bioengineer plagued by strange visions of unknown origin. They drive him to create artificial life forms called Patents, hoping to make an ultimate being that could change his life for better or worse.
Lang's mystery
Dark forces that control the City have their own plans for Lang's work and use their vast resources to advance their agenda. As Lang tries to solve the mystery behind his visions, he encounters intriguing and alluring, but also dangerous characters across the City's shadowy sprawl.
The story explores how far someone might go to escape the darkness of daily life, and whether salvation can rest on otherworldly visions and seemingly depend on one person born from them.
