In Hearts Of Iron IV history can be fully relived or rewritten from the perspective of a global superpower attempting to change the world, or a small nation simply trying to survive. World War II is at your fingertips as you guide your nation, plan your research, build you forces and design sweeping battle plans that will put the world at your feet.

Take control of any nation in the world and guide it through humanity’s most trying hours. With a new and improved battleplan system, you will be able to direct sweeping movements of troops through steppes, deserts and jungles. Area and mission based systems take the micromanagement out of naval and air combat. Strategy fans will discover the most authentic real-time simulation of World War II to date, with authentic historical figures battling on land, sea, and air with period-accurate armies, vehicles, and newly discovered weapons of mass destruction – along with plenty of diplomatic and trade tactics.

In times of crisis, it is important to be nimble, especially when you are the weaker party. Pay attention to the swiftly changing winds of diplomacy, build an army that can take advantage of weather and terrain to outfox a superior foe, and find alternate paths to prosperity and security. Sometimes, Winter is your only ally. Even if you can’t retreat into the cold forests, there are tactics and techniques available to anyone who would take Arms Against Tyranny.

Arms Against Tyranny is the latest immersion pack for Hearts of Iron IV, Paradox Interactive’s best-selling grand strategy wargame about the years around World War II. In Arms Against Tyranny, players will encounter new alternate histories and National Focus Trees for the nations of Scandinavia and Finland, with a heavy emphasis on the Winter War and Finland’s struggle against Soviet invasion.

This pack also includes new ways to develop your armament industries, and sell weapons designs to warring nations.

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.

Features of Hearts of Iron IV: Arms Against Tyranny include:

• 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.
