게임 정보

🔊 "End of the line. Please exit the train."

Experience a unique and personalized horror experience thanks to artificial intelligence.

An abandoned metro. A shifting labyrinth. A voice that knows your name.

You wake up alone in an infinite underground network, with no memory of how you got there. The tunnels whisper, the walls move when you're not looking, and something unseen is watching. But you are not truly alone—there are others here. Or at least, there were.

🚇 Will you reach the surface? Or will you become just another missing passenger?

Key features

• AI-Driven Storytelling – The game adapts to your choices, creating a horror experience that is uniquely yours.

• Your Journey, Your Choices – How you interact with others determines your path. Will you find the way out, or uncover something far more unsettling?

• Immersive Voice Interaction – Speak directly into your microphone to communicate with in-game characters—no typing required. (Text-based options are also available.)

• Full Localization – Enjoy the experience in your preferred language, with localized text, audio, and UI.

Compatibility disclaimer

LLMs (Large Language Models) in games are still new. These require a lot of computing power and cannot run on certain devices. Please keep the system requirements in mind. We aim to provide an optimized experience for any (supported) individual setup.
