Developed by Paradox Development Studio · Published by Paradox Interactive






Take command of a nation during World War II and guide it through the conflict. You decide how to pursue national objectives while responding to shifting wars and alliances.
Develop industry and direct factories toward military production, research new equipment, and build diplomatic relationships. Political choices can also open different paths for your nation.
Plan campaigns by organizing army divisions and choosing where to attack. Decisions across politics, production, research and warfare can lead to alternate historical outcomes.
Players who enjoy the game often point to its strategic depth and the many ways to shape a World War II campaign, including alternate historical paths. Some describe it as highly replayable and absorbing once its complex systems begin to make sense; others say the learning curve is steep and criticize the cost or completeness of DLC.
Take charge of history’s greatest war machines in Hearts of Iron IV, a grand strategy wargame that challenges your strategic abilities and political insight. Refight World War II at the head of nation from the time period, building up an industrial powerhouse and a diplomatic alliance that will effectively wage war on ideological opponents.
Hearts of Iron IV is more than a historical simulation. Alternate historical paths open up with almost every decision you make, from small ones such as where to launch your attack to crack open Fortress Europe, to large ones, such as whether to re-establish democracies or long forgotten monarchies.
In Hearts of Iron IV, you can plan the military strategy almost down to the rivets, as you design division templates for your armies, research new modes of production and means of destruction, set out factory instructions and pursue political objectives. Almost no part of the war goes untouched as you guide a nation of your choice through humanity’s darkest hour.
