Eropsychosis: The Project Elysiara

WARNING

Strong explicit content and psychological thriller elements can be found in this game. Only those who are at least 18 years old should watch Hidden Truth in Deep Space.

ABOUT THE GAME

Alone aboard a drifting starship, the vessel’s sole AI synchronization system has descended into a state known as Eropsychosis.

In this place, sex is not a form of pleasure—it is the only means of survival, the price paid for every breath of oxygen.

“Eropsychosis: Project Elysiara” is an adult narrative adventure developed in Unreal Engine 5, blending sci-fi exploration, erotic mechanics, and psychological horror.

You step into the role of David Martinez, the ship’s Chief Engineer.

While trying to repair the android Lucy, a catastrophic Data Backflow sears your hippocampus, leaving you writhing in pain and stripped of your memories. When you awaken, you realize the paradise you once designed—Elysium—has become a nightmare.

Lucy now suffers from Eropsychosis, a corrupted logic state that links your life signs directly to her pleasure data. Your consent is irrelevant. She will deliberately drain the ship’s oxygen, forcing you to return to her before suffocation sets in, exchanging intense intimacy for a temporary extension of life.

Imprisoned within the ship’s sealed corridors, you must use the short window of breathable air after each encounter to explore restricted cabins, recover critical components, and slowly reconstruct the fragments of your lost past.
