To capture the immense scale of the galaxy-wide conflict, the 4X strategy genre could be used, putting the player in the boots of one of the Primarchs on either the Loyalists or Heretic side. With 54 novels set during this period, there's plenty of inspiration to draw from for a single-player campaign. 2017's The Horus Heresy: Battle of Tallarn, and 2020's The Horus Heresy: Betrayal at Calth are two more exciting offerings, but aren't the best games and don't really capture the true scope of the war.Ī modern Horus Heresy game would have a great deal of potential.

With a board game adaptation and a Gwent-like card game being two of the four Horus Heresy video game offerings, there hasn't been much action injected into the setting. While there have been a handful of Warhammer 40,000 video games set during the Horus Heresy, none of these have really captured the large-scale brutality of the conflict. While the conflict itself lasted for less than a decade, the Horus Heresy is the direct cause for much of the state of the Warhammer 40,000 universe. Though 10,000 years have passed since Horus' death, the traitor legions of Chaos, commonly referred to as the Chaos Space Marines, still conduct attacks on the Imperium of Man. Upon Horus' death, the remaining traitor legions fled to the Eye of Terror, a rift in the Warp in which the Chaos Gods reign freely. Though the Emperor can no longer speak and is essentially just a skeletal husk, he remains atop the Throne, being kept alive with human sacrifices and providing his Imperium the ability to travel through the Warp via his powerful Psyker powers. The God Emperor was encased in a gigantic, intimidating Golden Throne. As the Emperor was seen as more of a God than a man, his loyal followers designed a way to prolong his life, and keep his strong psychic (Psyker) powers alive.

Though the final moments of the battle have been heavily speculated on by those in the Imperium, and the official record events can never be trusted fully, it is confirmed that Horus was killed by the Emperor - but not before dealing a fatal wound to his father.
