Warhammer 40,000: Gladius - Chaos Space Marines

Warhammer 40,000: Gladius - Chaos Space Marines adds the Chaos Space Marines as a new playable faction to the base game. This faction utilizes unique mechanics including Boons of Chaos, where champions may be elevated to Daemon Prince or transformed into Chaos Spawn; Veterans of the Long War, granting combat bonuses against Space Marines; Unholy Rites, consuming population for temporary buffs tied to worship; and Marks of Chaos, providing permanent unit enhancements through devotion to one of the four Chaos Gods.
