Aboard a scientific mini‑submarine barely 3×2 meters in size, equipped with archaic systems typical of the 1930s, you must manage real parameters such as pressure, battery, oxygen and temperature while solving escape‑room‑style puzzles and confronting abyssal anomalies capable of distorting reality, the senses… and even your memories.

Your main objective is to extract, using the mechanical arm, a sample of the inexhaustible energy source hidden within the core. As secondary missions, you can explore and scan unknown abyssal life, expanding the expedition’s scientific record.

The experience blends claustrophobia, constant tension, and John’s emotional breakdown, as visions of his lost family are twisted by the abyss to strike where it hurts most.

In 1938, the classified expedition codenamed “Last Breath” sought to achieve the deepest manned descent in history. No one agreed to participate… except John, a man devastated by guilt after an accident that destroyed his life. For him, this mission is not science—it is penance.

The descent to 10,000 feet drags him into a hell of pressure and heat comparable to that of a star, where he must tear from the planet a sample of inexhaustible energy with the potential to reshape humanity’s future.

But before that, John must survive the most hostile journey ever attempted, facing not only the cold, hostile abyss but also anomalies that twist his memories of what torments him most.
