Hearts of Iron IV

Hearts of Iron IV puts you in command of any country during the 1936-1948 window, and the simulation runs deep enough that you can fight the war from the factory floor up. National focus trees give every major and most minor powers branching political and historical paths — restore the Habsburgs in Austria, push Britain toward a fascist coup, or have the Confederacy rise in the American second civil war.

Division templates let you specify the exact composition of your infantry, armor, mountaineer, or marine units, then mass-produce them on the factories you build and assign. Military planning happens on a strategic map where you draw battle plans, set offensive arrows, and let your generals fight under broad doctrine settings — or take direct control of every army when you want to.

This package includes four expansion packs: Death or Dishonor for eastern European middle powers, Together for Victory for the British Commonwealth, Waking the Tiger for the China-Japan theatre, and Man the Guns for naval and American alternate history. Alternate paths open up at almost every decision point — restored monarchies, surviving democracies, or unexpected coalitions.
