In Hearts Of Iron IV history can be fully relived or rewritten from the perspective of a global superpower attempting to change the world, or a small nation simply trying to survive. World War II is at your fingertips as you guide your nation, plan your research, build you forces and design sweeping battle plans that will put the world at your feet.

Take control of any nation in the world and guide it through humanity’s most trying hours. With a new and improved battleplan system, you will be able to direct sweeping movements of troops through steppes, deserts and jungles. Area and mission based systems take the micromanagement out of naval and air combat. Strategy fans will discover the most authentic real-time simulation of World War II to date, with authentic historical figures battling on land, sea, and air with period-accurate armies, vehicles, and newly discovered weapons of mass destruction – along with plenty of diplomatic and trade tactics.
