Trapped deep beneath the earth in an underground complex, you wake to the beep of a countdown. Explosives have been armed. Lights flicker. Walls breathe. You don't know how you got here — but you know one thing: when the music stops, so do you. Navigate a looping, ever-changing labyrinth where nothing stays the same for long. Shadows twist wrong. Objects duplicate. Faces lie. You are being watched — but by what, and by how many, you cannot tell.
