    hearts-of-iron-4-graveyard-of-empiresGraveyard of Empires Opens Host of New Alternate Histories

    Imperial ambitions collide in the challenging lands of Central and South Asia. The British Empire is secure in the Raj and Iraq, but has long held designs on influencing oil rich Iran and unconquerable Afghanistan – also targets of an aggressive Soviet foreign policy from the north. Rewrite the history of a region caught between bowing to a larger alliance and homegrown dreams of national strength. Can you defy the odds and possibly resurrect the glories of a far distant past?

    Choose the fate of a nation seeking a new destiny or ancient prestige in Graveyard of Empires, a new country pack for Hearts of Iron IV. Follow the historical path of Afghanistan, India, Iran or Iraq or explore dramatic alternate histories with the rebirth of old empires.

A large focus tree focused on the struggle of Indian Independence offers many alternate historical paths, including the revival of the East India Company as a corporate nation, as well as the possible freedom of the Princely States, restoration of the Mughal Empire and more.
  • Iraq: Take control of this British client state and try to chart your own path, embracing the calls for pan-arab nationalism and siding with the axis against the allies. Manage the many competing ethnic and religious factions in Iraq and develop the strategically important oil fields.
  • Afghanistan: The historic Graveyard of Empires, isolated from the wider war, offers many alternate paths. Continue the historical path of neutrality and isolation, or choose the road of rapid industrialization and building a new power in the mountains of Central Asia.

    • Hearts of Iron IV: Graveyard of Empires also includes new art, with more leader portraits, infantry models and unit models.
