You are alone.
The return elevators have stopped functioning. Trapped inside the Clockworks with no weapons, no allies, and no resources, you must use your wits to escape to the surface alive before the monsters find you.
That's not to say you're the only one in the same situation, though. Several other poor souls like yourself are lost down here; if you can find them, you stand a greater chance of surviving the journey back to the surface.
And if you're lucky, maybe you'll find out what the heck is going on before you die.
