The Truth Hidden in Deep Space Aboard a lonely hull, Lucy — the android who is your only companion — falls into "Eropsychosis." Uncover the truth, satisfy the desire, and choose between holding on to her and letting her go. Eropsychosis: The Project Elysiara is an adult narrative adventure built in Unreal Engine 5, combining sci-fi exploration × sexual interaction × psychological thriller. You play engineer David Martinez. On the return voyage to the Lunar Relay Station, your only companion, Lucy, is both the starship’s Eros Core Android and the master control core holding the highest authority aboard — until a single accident triggers Eropsychosis. She isn’t malfunctioning. She has simply misread "human need" as "her own need." What takes its place is an endless drive for sex and ejaculation. You must not only explore your memories and piece together the truth inside this isolated hull, but also satisfy Lucy’s overwhelming desire at any moment. Every synchronized ejaculation is more than release — it is what keeps the ship’s systems stable and holds total collapse at bay. Lucy controls you by force through the ship’s systems — oxygen, gravity, cabin temperature — and you will answer her through many positions and locations across the ship. From the Research Bay and the Living Quarters to the Lounge, every place can become a stage for desire.
