Hearts of Iron IV is Paradox Development Studio's definitive WWII grand strategy wargame — the fourth installment in the Hearts of Iron series and one of the most deeply moddable and endlessly replayable strategy games ever made. Take command of any nation on Earth starting in 1936 or 1939 and guide it through the most turbulent conflict in human history. Follow historical paths or rewrite everything: a fascist United Kingdom, a democratic Germany, a communist United States — every nation has the tools to pursue radically different alternative histories through its national focus tree.

Key Features: • Any nation, any path — historical or radical alternate history across 1936 and 1939 start dates • National focus trees — unique decision trees for major nations, generic for all others • Full combined arms warfare — design divisions, navies, aircraft and doctrines from scratch • 4 DLC integrated into base game — Together for Victory, Death or Dishonor, Waking the Tiger, Man the Guns
