The Alters is a sci-fi survival adventure game that challenges players to navigate moral dilemmas and explore branching narratives. Set on a hostile planet, you play as Jan Dolski, the last survivor of a crashed expedition. Utilizing a substance called Rapidium, you can create alternative versions of Jan—referred to as Alters—each influenced by pivotal decisions from his past. This unique mechanic allows players to interact with different character dynamics and experience various life paths as they make choices that impact survival and relationships.

In addition to deep narrative exploration, The Alters requires players to manage a mobile base, gather resources, and face the dangers of the planet's environment. With a focus on the consequences of decision-making, players must navigate through challenging scenarios while considering the balance between personal and mission-oriented goals. The game emphasizes the importance of planning and strategy as players explore unique biomes, uncover secrets, and confront deadly anomalies, all while reflecting on the fundamental question of destiny versus choice.
