The frontier survived the horrors of Red Mercy Canyon.

But beneath the earth, the dead were building railways.

One year after sealing the Hollow Below, legendary bounty hunter Elias Vale — feared across the Duskland Republic as The Hollow Gunman — returns from death itself when an abandoned railway station is consumed by creatures crawling from beneath the world.

Ancient ghost trains now roam the frontier.

Dead passengers whisper in the dark.

And deep below the badlands, the forgotten Black Road awakens once more.

Armed with twin red-plasma six shooters, a lever-action repeater, a brutal scatter gun and the ancient blade known as the First Fire, Elias is dragged into a war older than civilisation itself — a war between the Ferrymen of the Roads Below and the starving cosmic horror known only as the Hollow Below.

Joined once more by the monstrous mountain hunter Gideon Crow, the fearless Abigail, and the ghostly First Passenger, Elias descends beneath the frontier into buried rail kingdoms, endless dead stations and ancient underground empires where forgotten souls wait for trains that never stop.

But the deeper they travel, the more horrifying the truth becomes.

The Black Road was never evil.

It was a refuge.

A final road for the forgotten dead fleeing the Deep beneath the world.

Now the Hollow Below is infecting the Roads Below themselves.

Passenger trains across the Republic vanish into darkness.

Entire rail lines collapse beneath the earth.

And if the Heart Station falls, death itself will belong to the Deep.

As ancient ferrymen make their final stand beneath the world, Elias Vale must decide whether to save himself… or become the last ferryman and burn the roads forever.

Because some roads lead home.

Others lead below.
