An unprecedented catastrophe enveloped young souls who were not lucky enough to find themselves in a series of tests for their survival. Constant pain, their aspirations for life. Suffering that they will have to get used to. Anxiety that has become a part of their lives. Too much testing, isn't it? Our heroes, having managed to pass the first level, will be forced to endure and overcome the nuclear ash that has settled on their shoulders. But they weren't the only ones who survived, were they? There is only their faithful companion, who has become a potential salvation - this is a steam locomotive. The locomotive that gave hope to the surviving pioneers. But survival in the scorched earth is only part of what they will experience. Hope is what will guide them.
One by one... their lights... they will go off if you don't find a way to save them. Trapped in the abyss. Will you find a way to escape? Or will you disappear into the darkness forever?
