Hearts of Iron IV

About Hearts of Iron IV

Hearts of Iron IV is the kind of strategy game where you don't just control an army - you run an entire nation during World War II. Released in 2016 by Paradox Development Studio and Paradox Interactive, it lets you take charge of any country in the world starting in 1936 and decide how history unfolds. You manage diplomacy, industry, military production, and battlefield strategy to try to win the war or completely rewrite it.

Hearts of Iron IV feels like a massive WWII sandbox. Want to lead Germany to victory? Turn a small country into a global power? Or change history entirely? The game gives you the tools to do it.
