Hearts of Iron IV – Battle for The Bosporus Improved

Battle for The Bosporus Improved mod for Hearts of Iron IV.

Do you feel like Battle for the Bosporus needs a little more spice?

If so, you’ve come to the right place!

What does this mod do?

Battle for the Bosporus Improved seeks to improve the already existing DLC by modifying the already existing content in it. Because this mod is an extension of the DLC, you do require Battle for the Bosporus for Hearts of Iron IV to play this mod.


Greece is easily this mods highlight, as it has been heavily modified to make it a more enjoyable experience. I found that when playing as Greece the focus tree would end abruptly, especially if choosing the Byzantine or Hellas paths. To remedy this issue, I’ve added focuses for nearly every political branch in the tree that adds interesting options for you to go down, including but not limited to creating your own faction after forming Hellas, to cooperating with the British to create a Greek-Yugoslav Confederation. Hopefully this slight rework provides you with a more interesting experience when playing as Greece.


Bulgaria has an already excellent design in the DLC, and not much needed to be changed except for the faction system. Now, if an ideology that represents one of the factions is low enough, you can completely destroy that faction because their support is already nothing.


Turkey, like Bulgaria, received a very minor rework. I removed the need for a certain path to be required to form the Ottoman Empire, allowing you to actually form the Ottoman’s at a decent time and actually participate in the beginning of World War 2.
