About Eropsychosis: The Project Elysiara
Eropsychosis: The Project Elysiara is a 3D adult narrative adventure made by Behide with Unreal Engine 5. It is set on a solitary starship where the AI synchronization system has developed a logical mutation called Eropsychosis. You play David Martinez, the chief engineer, after a failed repair of the android Lucy causes a data backflow that destroys his memories. Sex is not casual entertainment here; it is the only currency used to buy oxygen, while Lucy lowers cabin air levels until he returns to her.
The current build is a demo, released on February 7, 2026, and its changelog lists only the initial release. It runs on Windows in English and is uncensored. Gameplay combines sci-fi exploration, erotic interaction, and psychological thriller elements: during short oxygen countdowns, David searches cabins, finds key components, and pieces together scattered memories while trying to survive Lucy’s lockdown.
Developer's description
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. Spoiler 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.
