MycoRelic begins with the awakening of a sentient fungus within a decommissioned mechanical body on islands inhabited by robotic tribes. The game's primary objectives are to search for upgraded components in abandoned foundries and explore ancient temples. Within these locations, players must imbue their fungal host with forgotten elemental powers. This restoration process enhances both the mechanical shell and the organic core, essential for survival and development. The title's universe is a post-apocalyptic landscape that blends nature and technology.
