Story Overview
Set in the 22nd century, you play as Ryley Robinson, the sole survivor of the crash of the spaceship Aurora on the alien ocean planet 4546B. With your lifepod barely functional, you must explore the vast underwater world, gather resources, build habitats, and craft equipment to survive. As you delve deeper, you uncover the mystery of the planet—the ruins of an ancient alien civilization, a devastating infection, and the fate of a previous expedition. The story unfolds through environmental storytelling, audio logs, radio messages, and encounters with massive leviathans.
