Take on the role of Jan Dolski, the sole survivor of a cosmic catastrophe, who fights for survival on an alien, threatened planet. Using the mysterious Rapidium and a quantum computer, Jan creates his alternative versions – Alters. Each of them is shaped by different decisions from the past, offering different skills, personalities and perspectives. Make difficult moral choices and manage a complex crew, made up of different variants of the same person. The relationship between the Alters shapes the course of the story, and each choice affects the fate of the mission and possible endings. Explore the surface of the planet in search of the resources necessary to expand your mobile base and produce tools. However, each expedition is associated with the risk of radiation, deadly anomalies and extreme weather conditions. Only proper planning and vigilance towards the day and night cycle will allow you to survive. Expand your base with new modules, such as laboratories or common rooms, and decide whether to use the resources you gain for the needs of the entire crew or to support a specific Alter. Every decision has consequences, and trying to please everyone can lead to conflicts. Traverse diverse biomes, uncover the mysteries of the planet, and face dangerous phenomena that often hide out of sight. The Alters is not only a fight for survival, but also a deep reflection on the impact of choices on people's lives.
