ONTOS is a sci-fi adventure about the search for truth in a space where reality itself ceases to be a reliable support. Aditi Amani arrives at the lunar complex "Samsara" hoping to understand her father's legacy, but instead of answers, she encounters a system of beliefs, experiments, and distorted memories. The past never sleeps here, and the truth is hidden beneath layers of delusions and deliberate distortions. Experiments and consequences Each challenge in the game challenges the boundaries of science, morality, and human choice. Experiments act as narrative tools, gradually peeling back layers of reality and leading to disturbing revelations. Solutions have no obvious correct outcome and often lead to unexpected results, forcing one to consider the price of knowledge and the responsibility for interfering with the fundamental processes of existence. The Samsara study reveals a complex labyrinth of meanings and spaces. Laboratories coexist with religious retreats, and technical systems are intertwined with philosophical symbols. Progress requires planning, attention, and a willingness to accept the consequences of one's actions. This journey is not about victory, but about understanding, which can be devastating. Features of the game An existential story about the nature of reality and personality. Systemic gameplay with experimentation and consequences of choices. A surreal lunar base with a deep history. Research without single correct solutions.
