Mod «Unification Wars» for Hearts of Iron 4 (v1.10.7)


The light of civilization gutters and fades as the Long Night threatens to consume humanity!

As the thirtieth millennium draws to a close, it seems that any hope for humanity may be finally lost. A galaxy-spanning empire has been reduced to shattered and disparate pockets of men and women trying to scrape out a meager existence, easy prey for the alien, the mutant, and worse. Terra, the cradle-world and heart of this once great empire, has not been spared. Starved of resources, embroiled in conflict, and degraded by a thousand years of ceaseless war, cruel Techno-Barbarian Warlords call themselves masters of the broken ruins of mankind’s birthplace. The seas have been boiled by atomic fire, and the earth soured by the blood of billions. There is no peace here, only the pause between wars, the ragged gasp of nation-states before their petty tyrants can muster their broken subjects to die beneath the guns and upon the blades of one another again. So it would continue, until the last life is extinguished, but for a single man. Beneath the Himalazian mountains, a visionary sees the time to act is almost arrived. He makes ready his allies, and sets into motion great plans. He sees a great crusade launched across the stars, the scattered scions of humanity reforged again, but first . . . first Terra must be unified, and forged into world that will once again shape the fate of the galaxy.

Thus begin the Unification Wars, and the end of the Long Night.


The Unification Wars Mod attempts to give players a chance to step into the Warhammer 40k Universe at a pivotal moment, letting them shape the fate of Terra as the Emperor of Man builds the foundations of the Imperium. With custom national focus trees, unit models, world map, technology trees, and more, this mod seeks to completely overhaul the game into a unique experience. With careful attention to lore, and the game-play mechanics to back it up, this mod allows you take control as a number of key players.

This mod is currently in Beta and therefor is only a teaser of things to come. Soon you will be able to take control as a number of key players. Become the Emperor and dominate the Pan-Pacific, bring Ursh to heel, and crack open the island fortress of Albion as the Imperium. Try to maintain your iron grip on the Pan-Pacific as Narthan Dume, even as everything starts to crumble around you. Dedicate Ursh to the Dark Gods in a bid to crush the upstart Master of Lines before he can complete his “Angels of Death.” Try to throw the biggest party ever as the Merican Baronies!
