Expansion Pass 3 revealed for Hearts of Iron IV

Dateline: 11/12/2026

Expansion Pass 3 for Hearts of Iron IV will include a rework of the United States nation with additional packs focused on smaller nations.

From Paradox Interactive:

Hearts of Iron IV brings the big guns in Expansion Pass 3, a new bundle of upcoming content for Paradox Interactive’s best-selling grand strategy wargame about the years around World War II. This Expansion Pass includes a long awaited reworking and updating of the United States and other American nations, as well as smaller packs focusing on smaller powers.

Expansion Pass 3 is highlighted by The Giant Wakes, the American themed expansion. Lead the industrial giant out of the Great Depression, build an Arsenal for Democracy that can stand against international aggressors and direct the future of the post-war world. This pack will also have new content for Canada and other countries in the region. The first content to be released will be To The Bitter End, a Focus Pack about Romania, coming next week.

The Hearts of Iron IV Expansion Pass 3 includes:

  • Songs of Liberty: A collection of three classic American patriotic songs, newly arranged by Paradox Interactive. This pack is immediately available to all who purchase Expansion Pass 3.
  • The Giant Wakes: This expansion focuses on the Americas, with a special dedication to the United States and its entry into the wider World War. Guide the United States through the Depression to build an industrial giant that can take on the world or guide Canada through this tumultuous era and carve out a place for themselves with their reworked content. If you are looking for something a little more tropical, jump in as one of the Central American or Caribbean nations and forge your path ahead in the USA’s backyard. Additionally there will be changes to Industry, Army Building, and Air landings.
  • To The Bitter End: This focus pack is centered on Romania and its particular challenges as an oil rich minor power, often swayed by the giants around it.
  • The Price of Peace: This theater pack offers new diplomatic options, including the League of Nations, as well as new national content for Burma, South Africa, Yugoslavia and Venezuela.

On the eastern edge of Europe, Romania faces both domestic and foreign challenges. Ruled by a king who would rather party than govern, and divided between would-be dictators and democratic forces, the nation’s oil fields would make it a valuable ally or conquest for any of the ideological factions competing for power in Europe. Decide the future of Romania in To The Bitter End, a new Focus Pack for Hearts of Iron IV, coming on 19 November.

Created in collaboration with modders Marijn ‘marijn211’ Vroegh, Vlad Alexandru Catalin, and Daniel 'Norrman' Norrman, To The Bitter End brings new attention and historical detail to an often forgotten front of World War II.

The content for Hearts of Iron IV: To The Bitter End includes:

  • Dictatorship and Monarchist Focus Paths: Rein in the hedonistic King Carol II and enforce a military dictatorship, or embrace the Romanian Monarchy and reinforce its position on the world stage.
  • Democratic and Communist Focus Paths: Oppose Royal meddling with state affairs and form a coalition to reform Romania's constitution and democracy, or entice the masses, start a revolution and form a new red government to lead your nation into the future.
  • Two Flavours of Fascism: Overthrow the sitting government with the help of the Iron Guard and decide how to rule the nation. Sideline the hardliners and exert your control over the Balkans, or empower them and start your crusade against Communist influence.
  • Romanian Industry: Rely on your agricultural backbone and your domestic oil, or make the choice to modernise your nation and build up your own arms industry.
  • Entente Diplomacy: Call on the shared history from the previous war to build new partnerships with former allies.
  • International Cooperation: Invest in international relations with different countries and align with them for deeper co-operation.
  • New 3D and 2D Art: A new model for Romania’s ‘Vânători de Munte’ mountain troops, and a 3D depiction of the Romanian Arcul de Triumf, as well as the addition of many new and updated character portraits and focus icons.
  • Music: Two new themed music tracks that will round off the experience.
