About this game Read the full description
Hearts of Iron IV: Arms Against Tyranny
Four Northern democracies are seemingly helpless against nearby predatory dictatorships. Despite their size, Finland, Norway, Denmark, and Sweden have a chance to avoid conquest through clever diplomacy or fierce resistance. Write a new history of the Nordic countries in Arms Against Tyranny, a new expansion for Hearts of Iron IV.
This expansion to Paradox Interactive’s celebrated grand strategy wargame about the tumult of the years around the Second World War adds new focus trees and alternate histories for the northernmost nations of Europe, customization of weapons manufacturers, and new ways to take advantage of neutrality to profit your own citizens.
