"Styxton" is a nonlinear black-and-white visual novel in the horror genre. The year is 2018. A small town is gripped by panic: over two weeks, three young women have been brutally murdered. Each victim bears the same mysterious brand and has had her tongue cut out. The investigation has hit a dead end, and fear has become a part of everyday life. Three victims, one brand—and you are the living proof. Why did the maniac spare you?

You are Artem, a student whose dreams of becoming a filmmaker and starting a new life died along with your father and a personal tragedy, leaving you stranded in this backwater town. Your world has long been devoid of color due to achromatopsia, and after the attack on the banks of the Styx River, your memory of that night was erased. You are the only surviving witness. To uncover the truth, you will have to investigate a series of brutal murders, relying on your distorted perception of reality and the fragments of lost memories from that fateful evening. Your decisions will determine whether you unravel the mystery and discover who or what is behind this nightmare.
