If you are looking for the rules and lore inside, here is what it covers:
1. Major Alien Factions (The "Big Guns") The book provides deep-dive stat blocks and tactical advice for fighting the primary enemies of the Imperium:
2. The "Minor Xenos" (Unique Creatures) This is where the book shines for lore fans. It introduces or expands upon lesser-known alien races from the 40K universe, including:
3. Game Master Tools
The book concludes with a full, ready-to-play adventure titled The Silence. A Deathwatch Kill-team is dispatched to a dead world where a Necron Tomb World is awakening, only to find that a third, unclassified xenos species has begun hunting the Necrons themselves. It is a masterclass in atmosphere and paranoia.
Released in 2010 as a sourcebook for FFG’s Deathwatch RPG line, Mark of the Xenos is not just a monster manual; it is a hunter’s dossier. While the core Deathwatch rulebook provided the tools to build a Kill-team, Mark of the Xenos provides the prey.
The title itself is a double-edged reference. In the lore, the "Mark of the Xenos" refers to the Inquisitorial seal placed upon a world condemned for alien infestation—a death warrant signed by the Imperium. Within the pages of this book, it becomes a field guide to the biological, psychological, and tactical breakdown of the galaxy’s deadliest xenos species.
In addition to the major races, "Mark of the Xenos" often shines a light on lesser-known species mentioned in 40k lore but rarely given full model ranges. These might include:

The Great Rift has split the sky!), this book serves as a reminder of the eternal, static horror of the alien.
Whether you are a Game Master looking to terrify your players with a Lictor that uses actual stealth tactics, a lore master researching the lost races of the galaxy, or a collector seeking the final piece of your Deathwatch library, finding a clean, readable copy of this PDF is a rite of passage.

The Mark of the Xenos
In the grim darkness of the far future, the Imperium of Man was beset on all sides by threats. The unending wars against the alien, the heretic, and the mutant had taken their toll on the Imperium's resources. On the remote planet of Molech, a world on the edge of the Segmentum Obscurus, the Imperium's grip was tenuous at best.
Brother Arcturus, a battle-hardened Space Marine of the Cadian Shock Troops, had been dispatched to Molech as part of a scouting party. His squad had been tasked with investigating strange energy signatures emanating from the planet's long-abandoned underhive. The rumors spoke of an ancient xenos artifact hidden deep within the hive's tunnels, one that could potentially tip the balance of power in the Imperium's favor.
As Arcturus and his squad descended into the underhive, they were met with an eerie silence. The air reeked of decay and corruption, and the walls seemed to whisper with the psychic residue of long-forgotten civilizations. Their auspex devices began to pick up increasingly strange readings, like the ghosts of technologies long past.
Suddenly, the squad was ambushed by a wave of twisted, humanoid creatures. Their bodies were distended and elongated, with long limbs that seemed to defy the laws of nature. Arcturus recognized the markings on their foreheads – the telltale sign of the Genestealer, a xenos species infamous for their ability to infiltrate and subvert human societies.
The Space Marines fought valiantly, but the Genestealers seemed to be everywhere. Arcturus found himself facing off against a particularly massive specimen, its eyes glowing with an unnatural intelligence. As he clashed with the creature, he felt a sudden jolt of insight – the Genestealers were not the only xenos threat on Molech.
Deeper in the underhive, Arcturus discovered a hidden chamber filled with ancient relics. At the room's center lay the artifact: a crystalline orb etched with strange, Eldar glyphs. As he reached out to claim it, the orb flared to life, imbuing him with a vision of the distant past.
In the vision, Arcturus saw the Eldar, ancient and proud, as they forged the webway – a labyrinthine network of dimensional tunnels that crisscrossed the galaxy. He witnessed the birth of the Great Rift, a catastrophic event that had shattered the webway and plunged the galaxy into darkness. I cannot provide a direct link or copy of the PDF
The vision faded, leaving Arcturus stunned and disoriented. As he stumbled back to his squad, he realized that the Mark of the Xenos – a symbol of the Genestealer's corrupting influence – had been impressed upon his power fist. The taint of the alien was now a part of him, a constant reminder of the dangers that lurked in the shadows of the 41st millennium.
The Cadian Shock Troops would have to be cautious, for on Molech, the line between friend and foe had grown perilously thin. The Mark of the Xenos had been claimed, but at what cost?
