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.

I have to say Arms Against Tyranny left me disappointed. The focus trees for Finland, Sweden, Norway, and Denmark are okay on paper, but in practice they feel overly niche and don’t really make the game more exciting.

Pretty cool. Great focus for Denmark and Finland and good ones for Sweden and Norway. The market mechanics are great which gives small and non aligned nations a little bit of immersion in the war and not stay standing still.
