Today, Paradox Interactive announced Hearts of Iron 4: Expansion Pass 3, a new content bundle for its World War II grand strategy game that will overhaul the United States and other American nations, along with several smaller content packs. Priced at $43.99, the Expansion Pass is available now.
Hearts of Iron 4 Expansion Pass 3 includes three upcoming content releases, plus an immediate music pack featuring newly arranged versions of three classic American patriotic songs. The centerpiece is The Giant Wakes, an upcoming expansion focused on the Americas, with particular attention to the United States and Canada.
Players can guide the United States out of the Great Depression, expand its industrial capabilities, and build an Arsenal of Democracy capable of confronting international threats as the wider World War unfolds. The expansion will also add updated national content for Canada, along with additional opportunities to play as Central American and Caribbean nations. Further changes will address industry, army building, and air landings.
Hearts of Iron 4: Expansion Pass 3 also includes To The Bitter End, a Romania-focused pack scheduled to launch on November 19, 2026, for $5.99. The content explores Romania’s political instability and strategic importance during World War II, with players deciding the nation’s future under King Carol II.
Despite its internal divisions, Romania’s substantial oil reserves make it an important potential ally or target for the competing ideological powers across Europe. To The Bitter End introduces several political paths, allowing players to establish a military dictatorship, strengthen the Romanian monarchy, pursue democratic reforms, or embrace communism.
Additional fascist routes let players overthrow the existing government with help from the Iron Guard, choosing between consolidating their own authority or empowering hardliners to pursue an aggressive campaign against communist influence. Romania’s economic and diplomatic development will also receive attention, with options to strengthen its agricultural foundations and domestic oil production or modernize its industrial and military capabilities.
Players can pursue diplomatic partnerships with former allies through the Entente, deepen international cooperation, and build relationships with other nations. The pack will additionally introduce a new model for Romania’s Vânători de Munte mountain troops, a 3D depiction of the Arcul de Triumf, updated character portraits, new focus icons, and two additional music tracks.
The final major content release included in Expansion Pass 3 is The Price of Peace. This theater pack will introduce new diplomatic options, including the League of Nations, alongside additional national content for Burma, South Africa, Yugoslavia, and Venezuela.
Completing the bundle is Songs of Liberty, a collection of three classic American patriotic songs newly arranged by Paradox Interactive. This music pack is available immediately to everyone who purchases Expansion Pass 3.
To The Bitter End was developed in collaboration with modders Marijn Vroegh, Vlad Alexandru Catalin, and Daniel Norrman, bringing additional historical detail to Romania’s role in World War II.
