Hearts of Iron IV Wiki
Draw the front, fuel the tanks, and don't unpause into 1939 unready

The loop
Hearts of Iron IV is Paradox's WWII grand strategy game. You manage industry, research, and divisions, then unpause history — or rewrite it with a focus tree.
Build civs then mils, template a division that supplies, assign armies to a front, and fight when the logistics can take it.
First moves
- 1.Play Germany, Italy, or the 1936 tutorial-ish majors on Recruit. Micro-nations can wait.
- 2.Learn the production screen before fancy navy. Guns and trucks win land wars.
- 3.Use the battle planner as a teacher, then micro the important attacks.
- 4.Read supply maps. A beautiful encirclement that starves is a defeat.
