Parasite Inside

A silent ship in deep space. An unknown alien parasite. And only one person can face the truth. Parasite Inside is a third-person adult sci-fi horror adventure starring engineer Oni Lim, set aboard the massive colonization vessel COLOS-8. Explore silent corridors, uncover terrifying secrets, and face the evolving threat that reshaped the ship. This experience blends psychological horror, sexual themes, and mature biological concepts, all driven by the parasite’s influence on human bodies and minds. Every step brings you closer to a truth far more disturbing than death. COLOS-8 Once humanity’s drifting hope—now its silent prison. A colossal interstellar colonization vessel designed to carry thousands of sleeping settlers toward a distant world, the COLOS-8 was humanity’s fortress against the hostile emptiness of space. But after a catastrophic impact allowed an unknown alien organism to infiltrate the ship, that fortress became vulnerable. Now damaged and eerily quiet, COLOS-8 continues on its programmed course through the void—filled with unanswered questions. ONI LIM Chief engineer. Reluctant survivor. A mind the parasite cannot break. Oni Lim serves as the chief engineer of the COLOS-8, a brilliant specialist whose life was shaped by logic, structure, and machinery long before the disaster. Unlike soldiers or trained operatives, she survives through knowledge, caution, and ingenuity—not combat experience. Awakening from cryosleep, Oni finds herself caught between duty and fear. She is determined to reach the truth behind the infection and save the remaining crew, despite the seductive whispers in her mind growing stronger with every step. THE PARASITE A whisper that spreads. A hunger without shape. It moves unseen through metal and bone, twisting the human form into something unrecognizable. No one knows where it came from—or what it wants. But every infected mind becomes quieter… and every heartbeat closer to surrender. Whatever this parasite is, it has already changed the future of the ship… and perhaps humanity itself. GAMEPLAY A tense, story-driven sci-fi horror experience where every step forward threatens the body—and the mind. Parasite Inside blends deliberate third-person movement, atmospheric tension, and narrative exploration aboard a vast interstellar ship. Progress is driven by discovery—unlocking new routes, revisiting earlier areas, and solving engineering-focused challenges woven naturally into the environment. Combat is dangerous and precise: a plasma sidearm, limited ammunition, and deadly encounters push players to think before they shoot. Boss fights demand spatial awareness and creative use of the environment to survive. The infection system erodes Oni’s mental stability. Lose enough, and the story turns—pulling you into the parasite’s perspective, where truth reshapes itself.
