To protect his young family from merciless corporate tyranny, Samuel Hyst signs up for the hazardous life of a salvage marine, the foot soldiers of a militarized deep space operation. Hazard pay is high for a reason, and Samuel must endure grueling tours of duty in the abandoned scrapyard quadrants of a war-torn universe. Endless wars rage across every galaxy, leaving damaged starships, rusted factories, and broken planets in their wake, all ripe for plunder by the desperate and the daring.

Ajax answers the call of duty and becomes an Einherjar space marine, charged with defending humanity against hideous alien monsters in furious combat across the galaxy. The Garm, as they came to be called, emerged from the deepest parts of uncharted space, devouring all that lay before them, a great swarm that scoured entire star systems of all organic life. This space-borne hive, this extinction fleet, made no attempts to communicate and offered no mercy.

After seven years of bitter war, the end has come at last for the conflict known infamously as the Horus Heresy. Terra now lies within the Warmaster’s sights, the Throneworld and the seat of his father’s rule. Horus’ desire is nothing less than the death of the Emperor of Mankind and the utter subjugation of the Imperium. He has become the ascendant vessel of Chaos and amassed a terrible army with which to enact his will and vengeance. But the way to the Throne will be hard as the primarch Rogal Dorn, the Praetorian and protector of Terra, marshals the defences.

The year is 1989. America has just invaded Noriega's Panama. And Specialist Bennett's platoon of Cav Scouts are in country… with, frankly, not a whole lot to do. Until a freak rainstorm somehow transports the entire platoon—Humvees, weapons, and all—to another world. A world controlled by a wicked Aztec god. The Land of the Black Sun. In a heartbeat, the Scouts find themselves fighting for their lives against savage beasts, witches, zombies, subhuman tribes seeking sacrifices… and even themselves.

Cadia licks its wounds in the wake of the Thirteenth Black Crusade. The heretic forces retreat on all fronts. The day is won. But Lord Castellan Creed cannot rest easy. Something tells him the assault was a mere prelude to something greater, something more final. He is right. Out of the Eye of Terror comes Abaddon the Despoiler, at the head of a warhost unmatched in scale since the dread days of the Horus Heresy.

A great darkness has befallen the galaxy, and the armies of Chaos are rampant. To survive, humanity must retaliate and take back what they have lost. By the will of the reborn primarch, Roboute Guilliman, is the Indomitus Crusade launched - a military undertaking that eclipses all others in known history. From the Throneworld of Terra does the Avenging Son hurl his fleets, their mission the very salvation of mankind.

Bruised, battered, and barely standing, Vandal soon returns to the cockpit to bolster the ranks of a desperate defense force. As he and his fellow Chevaliers attempt to hold back the flood of turncoats, spearheaded by a legendary cadre of off-world mercenaries, Vandal must learn to master the fickle and deadly upright tanks if he wants to live to see the next contract.

After more than 20 years in special operations, USMC Gunnery Sergeant Wolf Mathison wasn’t looking forward to retirement when—implanted with an experimental artificial intelligence—he deployed on his last mission with a platoon of Marine Raiders being sent to the Jovian moon Europa. The USS Jefferson was destroyed en route, though, and only Mathison and three other marines survived. Trapped in stasis, they were hurled into the outer reaches of the solar system, where they wouldn’t be found for hundreds of years.

In the 20th century Earth sent probes, transmissions, and welcoming messages to the stars. Unfortunately, someone noticed. The Galactics arrived with their battle fleet in 2052. Rather than being exterminated under a barrage of hell-burners, Earth joined their vast Empire. Swearing allegiance to our distant alien overlords wasn't the only requirement for survival. We also had to have something of value to trade, something that neighboring planets would pay their hard-earned credits to buy. As most of the local worlds were too civilized to have a proper army, the only valuable service Earth could provide came in the form of soldiers....

On a hot July day on the plains of Kansas, a US Army mechanized infantry company from the First Infantry Division gets a very vague warning order, and the young troopers saddle up on their steel beasts to go try to control "civil unrest".

Dominic's world had been a fairly simple life. To live his life to the best of his abilities, gain experience, level up, and strive to enjoy himself as best he could in a backwater. Which, while tough on its own, was made infinitely harder by his father being the local executioner. All of that becomes infinitely worse when his entire family is murdered. Dominic is then thrust into a war between noble houses that had been put on hold for generations. A war that the royal family lost, and now only had one true heir and claimant: Dominic Randolph.

Convicted of a minor traffic violation, Rev Pelletier is conscripted into the Perseus Union Marine Corps...for up to a 30-year term of service. Anxious to get back to his civilian life and job, Rev opts for a shorter term as a Marine Raider taking the fight to the enemy. But with extremely high mortality rates, can he and his friends survive until their term of service is over? 

Somewhere in the toxic Bone Pits, where mechanical nightmares roam, an emaciated and wounded young wolf clings to life. Wracked with pain, driven by instinct, it crawls across the subterranean landscape, avoiding the unnatural horrors that dwell there and seeking sustenance while fending off rats, insects, and other vermin stalking it as prey.

When an elite Dark Ops legionnaire dies under suspicious circumstances, his former teammates suspect foul play. Favors are called in and the notorious bounty hunter Tyrus Rechs is asked to find out what really happened. When Rechs uncovers a sinister plot that is much bigger than a simple murder, he’s pitted against a powerful, hidden, and protected form of corruption.    

When a bunch of interstellar scavengers approach Earth intending to abduct a few dozen humans and sell them into slavery in the darkest, they make the mistake of picking on Steve Stuart and his friends, ex-military veterans all. Unprepared for humans who can actually fight, unaware of the true capabilities of their stolen starships, the scavengers rapidly lose control of the ship - and their lives.
