About This Demo

Hidden Truth in Deep Space

In a solitary starship, your only AI synchronization system has fallen into "Eropsychosis."

Here, sex is not entertainment; it is the only currency to buy oxygen.

"Eropsychosis: Project Elysiara" is an Adult Narrative Adventure built with Unreal Engine 5, combining Sci-Fi Exploration × Erotic Interaction × Psychological Thriller.

You play as David Martinez, the Chief Engineer.

While attempting to repair the malfunctioning android Lucy, a fatal "Data Backflow" occurred, burning out your hippocampus. You wake up in searing pain, your memories gone, only to find that the "Elysium Paradise" you created has turned into a living hell.

Suffering from a logical mutation known as Eropsychosis, Lucy has bound your vital signs to her pleasure data.

She does not care about your will. She will actively lower the oxygen levels in the cabin, forcing you to return to her before you suffocate, trading high-intensity sexual union for the temporary right to breathe.

Trapped in this high-tech lockdown, you must utilize the brief respite after each "session" to explore the cabins within the limited oxygen countdown, search for key components, and piece together your scattered memories.

Game Features

• Next-Gen Visuals with UE5
  Unreal Engine 5 brings a highly detailed starship and realistic android body rendering for a fully immersive experience.

• Dual Exploration of Truth and Desire

  In this game, "sexual acts" are the key to unlocking survival time. While searching for lost memories, you must instantly satisfy Lucy's Eropsychosis demands.

• Diverse Erotic Gameplay

  Unlock various positions and ship locations (Research Lab, Lounge, Control Room, etc.) to experience different erotic scenarios.

  The demo version provides 2 sexual positions (Oral / Cowgirl) for players to experience.

Gameplay

• Light Puzzle Solving

  Step-by-step environmental exploration to collect clues and items, piecing together the secrets hidden deep within the ship.

• Free Exploration

  Move freely across different areas of the ship, from the Research Lab to the Lounge, collecting key items to advance the story.

In "Eropsychosis: Project Elysiara", loneliness and desire will consume you simultaneously.

The ship's secrets, your shattered memories, and Lucy's hunger are all waiting for your response.

Can you cure Lucy's Eropsychosis, or will you be trapped in an eternal loop of extraction?
