About Abyssal Echoes

You play as Dr. Elias Ward, a deep-sea researcher descending into the abandoned Station Erebus deep in the Mariana Trench. Your mission is to explore the ruined underwater facility and uncover what happened decades ago. Move carefully through flooded corridors, manage your oxygen supply, and use your equipment to navigate the crushing darkness. Every action drains resources, so you must choose when to move and when to conserve energy.

Abyssal Echoes blends survival and psychological horror in a deep-sea setting. The pressure of the trench is constant, and strange phenomena challenge your perception of reality. Solve environmental puzzles, discover logs and clues left by the station's former crew, and piece together the mystery before your oxygen runs out. Poki Games brings you this tense underwater experience where light, air, and sanity are all in short supply.
