Horus Heresy: The Galaxy's Greatest Betrayal

In the dying light of the 31st Millennium, witness the most catastrophic betrayal in human history unfold across a million worlds. This is the age when demigods walked among mortals, when the Emperor's most beloved son turned the galaxy to ash and ruin in his quest for power.

Behold the Legiones Astartes in their prime - eighteen Legions of transhuman warriors, each numbering in the hundreds of thousands, their gene-forged might unmatched across the stars. Watch as brother turns against brother, as the very foundations of the Imperium crack beneath the weight of civil war. From the virus-bombed ruins of Isstvan III to the final, desperate siege of Terra itself, every battle reshapes the fate of humanity.

Command the loyalist Legions as they stand defiant against impossible odds, or embrace the dark glory of the Traitor Legions as they march toward their twisted destiny. In this age of legends, every Space Marine is a hero of myth, every battle a saga that will echo through ten thousand years of darkness.
