ZAVOD plunges you into the post-industrial darkness of dead factories and silent machines. Beneath the great factory lies a labyrinth of underground passages where all light has gone. Once, life ran at full tilt here. Now there are only rats scurrying through the remnants of what was left behind. Or is there? Go deeper into the factory, learn its systems, find what you need to survive, follow every safety instruction — and stay alert for whatever is hiding in the depths.
