Eropsychosis: The Project Elysiara
A downloadable game
⚠️ WARNING: This game contains strong adult content and psychological thriller themes. Intended for audiences 18+ only.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.
