Mod «Finlandia Focus Tree» for Hearts of Iron 4 (v1.10.1 - 1.10.3)


Finland was a extremely active country during WW2, fighting a fairly successful defensive war against the Soviet Union in the winter of 1939. Then in 1941 joining Germany in the Operation Barbarossa against Soviet Union and then finally, in 1944 signed an armistice with the Soviet Union and being dragged into one last war against Germany.

Almost none of this is seen in Hearts Of Iron 4 though. Only the Winter War exists. Which is why I sought to make this mod in the first place. With this mod Finland has the option to join Germany against the Soviet Union and leave it if Germany is being pushed back.

There are also options to reform into a fascist or communist nations and achieve their goals of either creating a Greater Finland or spreading the revolution to other Nordic nations. The democratic path on the other hand allows you to form a faction with Sweden, Norway and Denmark while non-aligned path will be the most historically accurate path. In addition there is a monarchist path that allows you to change Finland into a Kingdom and be lead by one of three houses. House Hesse, Romanov or Bernadotte each with their own focuses and leaders.

The focus tree also contains ways to increase one's industry, mining, military tactics, manpower as well as paths for improving Finland's air and sea capabilities.

All of the branches have been made to be fairly realistic and to not make Finland overpowered while also taking into account Finland's real world actions and events pre- and post WW2.

    • Democratic, non-aligned, fascist, communist and monarchist government branches
