STOCKHOLM - 17 August 2023 - The wartime histories of Europe's four northernmost nations make captivating reading. There are tales of resistance and collaboration. Some advocate for neutrality while others fight against the darkness. Heroes are everywhere as they stand with the oppressed, or take arms against an overwhelming enemy. On October 10, you can relive or rewrite these stories in Hearts of Iron IV: Arms Against Tyranny.

When the world cannot help you, sometimes winter is your only ally.

Arms Against Tyranny is a new expansion pack for Hearts of Iron IV, Paradox Interactive's critically acclaimed and best-selling grand strategy wargame set in the years around World War II. In Arms Against Tyranny, players can explore deeper historical immersion when playing Denmark, Finland, Norway and Sweden. The Finnish Winter War against the Soviet Union takes center stage as you try to mobilize a sparsely populated nation to defend the homeland against almost impossible odds.

• New Finnish National Focus Tree: Walk the diplomatic tightrope of a democratic nation trapped between threats, develop a capable defensive army, or pursue alternate historical paths of collaboration with the neighboring tyrants.
• New Swedish National Focus Tree: Resource rich and fiercely independent, Sweden can be the center of a unified Scandinavian resistance, or a game-changing ally in the ongoing battle of ideologies.
• New Danish and Norwegian Focus Trees: With the benefit of hindsight, can you prepare these small nations for the storm of war that is about to wash upon their shores?
• Military Industrial Organizations: Customize your armaments industry by encouraging national corporations to specialize in the types of weapons and technology you desire for your armed forces.
• International Arms Market: Become the quartermaster of the world by selling arms and equipment to the warring nations, receiving civilian factory capacity in return.
• And more: New unit art, 10 new songs, customization of Special Forces units and greater divisional specialization.

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.

The release of Arms Against Tyranny will be accompanied by a major free update to Hearts of Iron IV, available to all Hearts of Iron players. This update includes free changes to Finland's historical National Focus tree.

Hearts of Iron IV: Arms Against Tyanny will be available on 10 October 2023 for the suggested retail price of $19.99/£16.75/€19.99.
