Ante Rebellum is a total overhaul alternative history mod for Hearts of Iron 4, made by a small group of internet friends for fun and to share our love of history and video games. AR's timeline diverges from ours in 1905, where the Russian-Japanese war destabilizes the Russian empire into a civil war that eventually causes the total collapse of the Tsardom.

Report any bugs here

Highlights of this timeline include:

•A cold-war conflict between a young Soviet-Republic lead by Trotsky and a sprawling Japanese empire lead by an increasingly liberal Diet.

•A global war in the late 1910s making Germany the dominant power in Europe

•A colonial race between Germany and Britain threatening to destabilize the British empire from over-extension

•A fragmented China torn apart by various warlords vying for control of the Republic.

•A massive red scare throughout the United States, leading to a decade of internal strife and a devastating war.

•A social-economic collapse of the established old order leading to a wave of radicalism throughout the world

Timeline of the lore from the point of divergence.

Will the old order manage to hold off against the tides of populism and dissent? Or will the onslaught of change wash over the entire world in a burst of fire and blood?

Planned Features for version 0.1:
-Hundreds of new events with diverging interactive paths

-Focus trees for several majors

-Complex event trees for many nations

-Dynamic wars and global conflicts

-Enhanced internal politics mechanic

-New soundtrack full of period pieces

Planned features for future releases:

-Hundreds more events and branching paths for all nations

-Focus trees for most nations with many diverging paths

-An overhauled internal politics and ministers system

-Graphics overhaul

And more!

All development on the mod takes place in our discord server

Ante Rebellum 0.1 Release

Here we are, ladies and gentlemen - Ante Rebellum 0.1 has been released. After some slight technical hitches and last-minute bug squashing, we feel that Ante Rebellum is full enough to go live to y'all - we hope you enjoy it

You can find the release on steam, if you so prefer, here -

What is there?

As of release, the mod contains the following:

Focus trees and events for - UK, Germany, Japan and the Soviet Republic

Events for - Syria, American state, USA, Austria, Hungary, France and parts of China.

We therefore recommend you play a country with a focus tree - namely the UK, Germany and Japan. Please note all focus trees are still being worked on are are liable to change, especially the Soviet tree.

What will there be?

We hope to bring a better Soviet tree along with improved localisation and bug fixes fairly soon.

After this release, we will work towards preparing the mod for the next Hearts of Iron 4 update, Cornflakes. The mod is fairly small at the moment, so hopefully we will be able to tightly integrate the new systems of war support and the huge decision system.

We will, as always, keep you posted.

And a big thank you to you!
