About Hearts of Iron IV

You take command of a nation during World War II and build it into an industrial and diplomatic power that can fight its ideological opponents. The game is more than a historical simulation: nearly every decision opens alternate paths, from where to attack to whether to restore democracies or long-forgotten monarchies.

You plan the war in fine detail. You work out division templates for each army, develop new weapons and production methods, give your factories their orders and pursue political goals. Few parts of the war are left untouched.
