Earthshock

You have journey long across blasted plains, through the ruins of old cities, and past the salt dunes, remnants of the oceans. Now your destination is at hand.

Mutants have trailed you for many days but you have always managed to keep one step ahead of their grossly radioactive bodies. As you neared the plains of ash, the tall ventilation shafts began to appear, the dark towers jutting from the black ash like a hand, clutching the granules of dust drifting through other, unseen drowned fingers.

As you explore, you find yourself trapped when a ledge collapses.
