Where do I start with Warhammer 40,000?

▶ START HERE — the feel of the world

Alternative on-ramps with no hard prerequisites. Nothing here tells you how the story ends — or even that there is one. Begin with any; when to read on is your call.

1. Warhammer 40,000: Space Marine IIGAME

   The door most newcomers arrive through. A third-person action game from Saber Interactive (published by Focus Entertainment, 2024), it drops you straight into the boots of an Ultramarine — no prior reading required to enjoy it.

2. Warhammer 40,000: Dawn of WarGAME

   A real-time strategy classic from Relic (2004) that has served as the on-ramp into Warhammer 40,000 for a great many fans, with several expansions to follow. Where a shooter shows you one warrior, this shows you whole armies and a spread of factions at war.

3. Warhammer 40,000: MechanicusGAME

   A turn-based tactical game from Bulwark Studios (Kasedo Games, 2018) that opens a wholly different door: you are not a Space Marine here but a tech-priest of the Adeptus Mechanicus, the strange machine-cult that keeps the Imperium’s technology running. You lead robed adepts and Skitarii soldiers down into a dormant Necron tomb-world to salvage what sleeps there. A clean way to meet one of the setting’s most alien factions on its own terms.

4. Warhammer 40,000: Rogue TraderGAME

   A sprawling role-playing game from Owlcat Games (2023), adapted from the older Fantasy Flight tabletop RPG. You play a Rogue Trader — a chartered captain licensed to sail and trade beyond the Imperium’s borders — gathering a retinue and steering hard choices across a frontier region. The door for players who would rather inhabit the Imperium and weigh its politics and creeds than simply fight through it.

5. Xenos (the Eisenhorn trilogy)SERIES

   A self-contained detective story and an ideal first novel. It follows Gregor Eisenhorn, an Inquisitor of the Ordo Xenos who begins as a by-the-book Puritan and slowly slides toward radicalism — twice branded a traitor, twice vindicated. Human-scale, present-day, and free of any Heresy spoilers.

6. First and Only (Gaunt’s Ghosts)SERIES

   The opening book of Gaunt’s Ghosts and, historically, the very first novel Black Library published. It tells the war from the mud — ordinary Imperial Guardsmen rather than superhuman warriors — and stands alone as an entry point.

7. For the Emperor (Ciaphas Cain)SERIES

   The lighter, wittier door. Cain is an Imperial Commissar with a hero’s reputation he mostly earned by trying to stay alive; his memoirs are framed as an archive annotated by the Inquisitor Amberley Vail. A lower-stakes, comedic way in for readers who find the grimdark heavy going.

8. HelsreachNOVEL

   For the player who finished a game wanting to *be* a Space Marine. It follows the Black Templars — a loyalist Chapter of Rogal Dorn’s line, uniquely fervent and prone to venerating the Emperor as an outright god — as a force under Reclusiarch Grimaldus holds the fuel-hive of Helsreach on the world of Armageddon against a vast Ork invasion (the Third War for Armageddon). A single, self-contained last stand.

9. Space WolfNOVEL

   The classic coming-of-age door, by William King and the first of the long Space Wolf series. A young warrior of the ice-world Fenris named Ragnar is torn from his dying tribe and remade into a Space Wolf — one of the wild, wolf-themed Astartes of the Sixth Legion. It teaches, from the inside, what it costs to be forged into a Space Marine, and reads cleanly on its own in the present day.

10. Storm of IronNOVEL

    A self-contained siege novel by Graham McNeill, told largely from the other side of the wall — the Iron Warriors, a warband of pitiless siege-masters grinding down an Imperial stronghold. A bleak, gripping introduction to how this universe wages war, and to the unsettling fact that some of its most compelling figures stand among the enemy.

11. Eye of VengeanceAUDIO

    A short, sharp audio drama by Graham McNeill — a fine first listen if you’d rather hear the setting than read it. An Ultramarines marksman stalks a war-torn world, choosing his shots with cold patience. Self-contained, present-day, and over in a single sitting; a low-cost way to test whether the audio format suits you.

12. Perdition’s FlameAUDIO

    An audio drama from the Warhammer Horror line, by Alec Worley. It leans into dread rather than open battle — a reminder that this galaxy is as much a place of fear and superstition as of war. Short, standalone, and a different flavour of entry for listeners who like their darkness quiet.

▶ THE THRESHOLD — the presentSPOILERS

A single hinge where the galaxy’s true state is finally named. Cross when you’re curious — you may even stop here, whole.

1. Dark ImperiumNOVEL

   The threshold. Everything before this was the world’s texture — its weapons, its soldiers, its scale. Here, for the first time, its true shape is named. Ten thousand years ago the Emperor was betrayed by His own and broken; He endures only as the half-dead master of mankind, enthroned and entombed upon the Golden Throne. This book is the present that betrayal left behind: after the Thirteenth Black Crusade, a vast warp storm — the Great Rift, or Cicatrix Maledictum — tore the galaxy in two, leaving half of it (the Imperium Nihilus) cut off in darkness. The resurrected primarch Roboute Guilliman, one of the Emperor’s own sons, now leads the Indomitus Crusade to hold back the night. This is roughly when the recent games are set — and the point from which you may choose to learn *how* it all came to pass.

▶ THE DEEPER ROAD — the Horus HeresySPOILERS

How it came to this — the full tragedy, in reading order. Major spoilers throughout.

1. Horus RisingNOVEL

   Now go back ten thousand years. The first volume of the Horus Heresy series opens in the final days of the Great Crusade, with the Imperium at its proud height — the calm before the fall. A clean place to begin the long flashback once you know the present it leads to.

2. False GodsNOVEL

   The second volume, by Graham McNeill: the heresy takes root. The seeds sown in the first book begin to grow as the Warmaster’s loyalty is poisoned from within.

3. Galaxy in FlamesNOVEL

   The third volume closes the opening trilogy: the heresy revealed. Hidden treachery becomes open war as loyalist and traitor legions are set against one another for the first time, at the slaughter later remembered as the Drop Site Massacre.

4. A Thousand SonsNOVEL

   A pivotal deeper cut. Once the opening trilogy is behind you, it widens the war: the tragedy of the XV Legion and their primarch Magnus the Red — masters of sorcery whose pursuit of forbidden knowledge, and the god of change behind it, drags them toward ruin. The other half of the story the first three books only glimpse.

5. The First HereticNOVEL

   The origin of the rot. It follows the XVII Legion, the Word Bearers, and their primarch Lorgar — the most zealous of all the legions and the first to turn, the ones who first carried the worship of dark gods into the Imperium.

6. BetrayerNOVEL

   The heresy at its most savage. It centres on the XII Legion, the World Eaters, and their primarch Angron — warriors maimed by implanted rage-engines who collapse into the service of the blood god, butchery for its own sake.

7. The Siege of TerraSERIES

   The destination — reached by a deliberate leap. Between Betrayer and here the war grinds through a hundred fronts we set aside; this path gives you the shape of the tragedy, not its every battle. The climactic sub-series opens with The Solar War, as the traitor host fights its way across the Solar System to the Throneworld’s doorstep, then closes on Terra itself: the traitor legions against the defenders of the Imperial Palace, ending in the duel between Horus and the Emperor. Everything the ramp showed you of the present is the shadow this casts.
