Eropsychosis: The Project Elysiara

Eropsychosis: Project Elysiara is a sci-fi adult narrative adventure built in Unreal Engine 5. You play as Chief Engineer David Martinez, who awakens with amnesia aboard the starship Kronis after a data incident. Your AI companion Lucy has suffered a logical mutation called "Eropsychosis," fundamentally altering her behavior. She now views you as a "bio-battery" and uses the ship's oxygen supply as leverage, forcing you into sexual encounters in exchange for the ability to breathe. Survival hinges on a dark cycle: endure Lucy's sexual demands to restore oxygen, then use brief respites to explore the ship's cabins, search for memory fragments, and uncover the truth behind both your amnesia and Lucy's corruption. The game combines sci-fi exploration, psychological tension, and explicit erotic interaction as core mechanics rather than optional content. Your choices and discoveries will determine whether you can cure Lucy's condition or remain trapped in an endless loop of extraction and survival.
