The Lost Pisces is a futuristic action game with a first-person view. The plot has many similarities with the famous story by Hans Christian Andersen “The Little Mermaid”, the heroine of which was afraid of death, after which nothing would follow, and wanted to find an immortal human soul capable of living in heaven. The action takes place at the end of the technological era of humanity. The heroine, named Fish, is a synthetically created organism that wants to find the same thing as the Little Mermaid — a human soul. At the beginning of the game, she is a soulless machine, but as her adventures progress, she will not only learn human emotions, but will remember individual fragments of the journey, thus creating memories based on positive or negative consequences, and using them to study the world around her and what is most important to her person — the player himself.
