On the ruined agri world of Moroch, amongst prefab colony habs, archeotech mines, and fronteris compounds, the ambitious Traitor Guard of the Blooded have all but overthrown their shocked Imperial overseers. Yet loyalist reinforcements have arrived in the form of an elite Phobos Strike Team, whose Space Marine operatives have commenced a hit-and-run campaign to take down the traitor forces one bloody gunfight at a time. Now, transhuman warriors battle degenerate, Chaos-worshipping renegades through the ruins of Moroch’s blasted frontier, each seeking nothing less than the wholesale annihilation of their enemies.
