The End of Days has come... but not for us. The UEC has been fighting a losing battle against the demonic hordes, forced to surrender more ground every day. But aboard the U.S.S. Shotgun Opera, the Overmaiden—a sixth-generation Ghost AI—has just forged humanity’s perfect weapon and best a supersoldier. The man he used to be is gone, lost with his family to demons on the mining world of Aonus. All that’s left is hate, rage, and unyielding power. Rip, crunch, gore, dismember—the unstoppable juggernaut will slaughter his way through Hell, driven by righteous fury and a singular drive. And he won’t do it alone. At his side are an exiled angel, a talented xenobiologist, and the Overmaiden herself—not to mention a battle-hardened squad of marines who've been doing this song and dance for years. Together, they’ll fight, bleed, and bear witness to his wrath. He is nameless. He is the Sword of Mankind. He is the Hellmarine.

The frozen world of Asarus, a critical lifeline for the colonies, is under siege by an icy demonic horde unlike anything humanity has faced. The Hellmarine and his squad are sent in to contain the chaos, but this time, the stakes are personal. As memories of a forgotten past claw their way to the surface, the unstoppable juggernaut finds himself haunted by more than just demons. With the Overmaiden orchestrating from the skies, Seraphiel watching his back, and a mysterious face from his old life stirring questions he’s not ready to answer, the Hellmarine must carve his way through legions of profane ice monsters to stop a Voivode powerful enough to warp reality itself. But this isn’t just war anymore—it’s survival. The cold burns, the ice corrupts, and the Hellmarine’s unyielding rage might not be enough to save Asarus... or himself. And that's only the opening chapters. Hellmarine 2: Neck Deep in Demon Blood takes the carnage and chaos to the next level with more action, more lore, and more Hellmarine fury. The fight for humanity’s future has never been deadlier—or more personal.

In a demonic plane beyond our own, at the bleeding edge of galactic battlefields, the Hellmarine waits. After being trapped in the merciless realm of Hellspace, the Hellmarine has killed time mostly by single-handedly decimating the Demonic legions that once threatened humanity. Clad in salvaged armor adorned with the skulls of his enemies, wielding weapons forged in the fires of endless combat, he is humanity's ultimate weapon against the forces that would consume the multiverse. And he's finally back. But his return to the SANS Midnight Sea comes hand-in-hand with new complications. Demonic insurgencies continue spreading throughout Alliance space despite closed Hellrifts. The ancient Zintari known as Kyn'Virak hunts his own kind with a singular, genocidal devotion. And a rogue colonel with terrifying otherworldly abilities has unlocked the secrets of Project Lazarus, creating an army of the undying. The Hellmarine and his allies must face down all this and more. Will they be up to the challenge? Who are we kidding? Of course they are.
