Hearts of Iron IV: Arms Against Tyranny

If you pre-order Arms Against Tyranny, you will receive a special bonus music track, a new arrangement of Säkkijärven polkka, produced by Magnus Ringblom. This Karelian-Finnish folk song was famously used by Finnish troops to prevent the Soviet army from detonating radio-activated mines. Played on repeat from radio vans, the Säkkijärven polkka jammed the Soviet radio transmitters to such an extent that the Finnish army was able to clear the minefields. Ringblom’s new arrangement is a tribute to ingenuity of the Finns as they tried to repel a larger foe.

Hearts of Iron IV: Arms Against Tyranny

Four Northern democracies are seemingly helpless against nearby predatory dictatorships. Despite their size, Finland, Norway, Denmark, and Sweden have a chance to avoid conquest through clever diplomacy or fierce resistance. Write a new history of the Nordic countries in Arms Against Tyranny, a new expansion for Hearts of Iron IV.

This expansion to Paradox Interactive’s celebrated grand strategy wargame about the tumult of the years around the Second World War adds new focus trees and alternate histories for the northernmost nations of Europe, customization of weapons manufacturers, and new ways to take advantage of neutrality to profit your own citizens.

The Winter War

Relive the defining moment of Finnish history, defying the odds in a war against a much more powerful Soviet adversary. Though disadvantaged in air and amored forces, Finnish forces have a strong advantage on homeland defence, so you should prepare an army specifically designed for Finland’s terrain to fight invaders. Or, if you prefer, write your own history, strengthening Fascist sympathizers who want a Greater Finland or pursuing a socialist path - with or without Soviet support.

A Powerful Sweden

The richest of the Nordic nations, Sweden is well-suited to a path of vigorous neutrality and to serve as both an arms designer and arms trader. Strong unions risk crippling unstable governments unless you can provide enough work. In a world on fire, Sweden must also upgrade its obsolete forces so it can defend itself. Can the Swedish democracy avoid taking the side of its occupied neighbors, or will the government collapse in favor of monarchist or Fascist alternatives?

Norway

Relive the historical challenge of a young industrializing nation trying to stay neutral in the face of German aggression or prepare for war by quickly arming to resist the war that is coming to your doorstep. In alternate historical paths, unscrupulous domestic fascists may take advantage of domestic complacency and pursue Nordic union through betrayal, or a Communist revolution can choose to stand with or against Stalin’s regime.

Denmark

A long-standing policy of neutrality leaves Denmark unready for a continental war. Pursue the course of domestic harmony through a strong welfare state and agile diplomacy, or throw in with the democratic Allies, rearming for the coming storm. Alternate paths include chasing the dream of a united Scandinavia, reviving the old Kalmar Union.

A War Machine of Your Design

To make sure you have an industry that matches your ambitions, national manufacturers and weapons designers can specialize their craft, improving the production and research of various items through the course of the war. Military Industrial Organizations will offer new ways to streamline production lines or develop high-performance weapons systems with advantages on the battlefield.

Guns for Butter

In the new International Market, you can become an arms exporting powerhouse, selling weapons to other nations in return for civilian factory output, increasing your own industrial production at home while fueling the fires of war abroad. This is a new way for rich and advanced neutral nations to stay viable and active in a world war.

New Military Options

Many updates and changes to the design and organization of military divisions, including customization of special forces units, divisional specializations, and more.

New Art and Music

New unit art, including Finnish snowmobile brigades, and 10 new songs inspired by the key cultures in Arms Against Tyranny.
