One hundred years ago, a war in Europe erupted which would change the world as we know it. Men were forced out of their homes, from their farms and apartments, to fight in seemingly neverending trenches, gaining meters and meters of ground a day at the cost of massive casualties.

Hearts of Iron IV: The Great War, an overhaul mod for Hearts of Iron IV, puts you in the position of one of the countries of the world in World War One's time period. In an era where the stakes were high and risks even higher, you'll have to tread lightly when it comes to diplomacy. A single mistake or a single bluff gone too far could mean the deaths of millions.

Of course, that's not to say that the Great War is the only thing on anyone's minds. Revolution is flaring up in China and Mexico, Italy is rumored to have designs on taking Libya, and the Balkan States seem to be banding closer against one of their foreign targets. With all this conflict across the world, the Great Powers alone won't be having all of the fun.

The War itself has been modeled to match more closely the flow and style of war of World War I. Infantry virtually alone will rule the Battlefield at the beginning of the Conflict, before Planes and Armored Cars will take the field in good numbers. Trench Systems will see construction throughout Europe, until a mad engineer's dream, the Tank, rolls out of the factory and onto the Battlefield. All the while, massive fleets of massive Dreadnoughts will fill the Oceans, with all sides vying to wrest control of the waters.

With elaborate National Focus trees that delve deep into Alternate History, you may find two games with the same country end up completely differently. What if the Zimmermann Telegram had never been sent? What if Italy decided to go hardline and fight with the Central Powers? In this Mod, the smallest divergences can change everything.

The Great War Mod, of course, is designed to attempt to emulate how Paradox themselves would have designed the scenario, so veterans of the World War II scenario and of the Hearts of Iron franchise will have no trouble adjusting. Even the new animations and models are designed with Paradox's standards in mind. You may just settle into the game so quickly, you'll wind up with trench foot and shell shock before you realize it.

Anyone know a mod, similar to this, but which also works all the way into the 1936 campaign? This does not. Versailly Treay never kicks in

Peace conference complete... no Versaille event happens. Tried the console option... but that only brought up an event, but nothing realy happened. Still cant use the options in the focus tree

Supernerd12 you need to beef up your history. World War One planning started in 1866 when crown prince Edward of England was approached for a war alliance with France to fight Prussia, since there was no German Empire at that time. The planning proceeded to include Britain, France, Belgium, Russia, the USA and Japan. In 1914 too much money and effort had been expended to stop the project. If Belgium for whatever reason would have abandoned its secret alliance with the Entente, the war would have gone ahead anyway.

I was playing as Canada and went the monarchist route and after using the national focus "Forging an Empire", that became my country name. Also, the regency council never ends despite finishing the focus to put Prince Albert on the throne.

yyo, where is the suez canal

There aren't really any alternative paths for the major nations.
Also, the reasearch system should be adapted to cover the additional years - I had researched everything to 1914 tech already in 1913.
Further, there are some weird diplomacy bugs (Italy entering the war on side of the Central Powers, then suddenly switching without any notification and invading my territory).
Additionally, the representation of the British guarantee to Belgium should be implemented since that was the actual cause for entering the war.

osmanlı imp. oynayıp, balkanları ele geçirdiğimde savaş baya geç başlıyor. savaş başlayınca oyun çok fazla kasıyor. not: güncel sürümde oynuyorum.
