Teaser On The Clouds Of Heaven - The Final Judgement Strange Sprite?

Hi People. I recently watched a video on the mod On The Clouds Of Heaven - The Final Judgement and I'm really confused as to what this Satan sprite is supposed to be? If anyone knows more than me please let me know. I feel like I'm very well educated on the Catholic and Orthodox faith and I'm confused as to what the hell this is supposed to be.

Discussion I am really excited for Pax Britannica

Thumbnail

33 Upvotes

I recently came across the beta version for Pax Britannica (I was informed it's already available to the public, the version I played is the beta for. Future updates) and the setting itself already sounded compelling enough, the idea of Queen Victoria becoming the Eternal Empress because Edison experimented on her for her survival, sounded like an intriguing premise.

Add on to that: a post Great War world with unique nations I hadn't seen before and creative ideas for different systems I immediately downloaded it.

I decided to play as my home country of Mexico to see what they were doing.

Mexico basically was the Ottoman of the Americas, once a powerful force that now has decayed and is slowly dying.

While right now it features limited content (only up to the reunification of lost lands of the empire) it's still a really interesting play through for all the events you get to see and the mechanic for managing loyalty of your states didn't feel too tedious but wasn't just a road bump either.

The big event you get as Mexico is the reclamation of your lost lands after you fix the Nation and sort of make it less horrible to live in.

When you pick the relevant focuses you immediately declare war on the North and South nations, whichever side you pick you get the bonus for it.

Honestly the war wasn't too difficult beyond California and Tejas.

Also another point I really like is the management of technology, given the unique setting you of course get some unique tech.

Featured in the second photo is the unique branch where you can research both chemical and biological weapons, plus stimulants for your troops.

The interesting thing is that for chemical weapons the damage is applied to whichever state you are targeting so it persists for a while which could be negative for you, the biological weapons have a unique feature as some can spread beyond the selected state quickly creating issues for you.

So they are essentially a double edge sword and have to be careful where you apply them.

In the third photo we see the tab of Augments and what I would call one of the highlights of the mod itself.

The amalgamates are essentially a hotpot of genes of animals put into a singular being that is then deployed in your front lines as divisions, they are decent ish and not too expensive (Australia has a nation where these creatures escaped and evolved and now haunt that side of Australia)

The other one I tested was the enhanced human and honestly I really liked the aesthetics of it.

The Razor maidens are essentially women who have gone extensive mechanical changes to their bodies making them an excellent special forces division and they are very fast as well plus can hit hard even punching through tank divisions with the right support.

I could keep talking on and on about various features such as the automatons, the space race between Russian and Britain, the Second Great War, the fractured America and the genuinely fascinating world build they are doing but this post has been long enough I feel and I would rather people experience that for themselves

ASEAN: A shattered paradise[Mod Concept] Reupload

Post image
• Upvotes

Hello everyone, I'm fairly new to Hoi4 in general and VERY new to Hoi4 modding. But looking at all these mod like TFR or Red Dusk(W for having Vietnam as a playable nation), I realized that I wanted to do something similar, But more closer to home. so I'll introduce to y'all, ASEAN: A shattered paradise.

Starting on January 1st 2025, The main point of divergence for the mod will be, what if the July 2025 Thai-Cambodian border conflict escalate into a full scale war. As communications fail between all countries, Thailand and Cambodia mobilized their nation. During this time, a covert Thai operation of them sneaking through the Laotian border to flank Cambodia, was busted. For that, Laos declare war on Thailand. Vietnam, seeing both of their neighbors are at war, secretly aiding both nation with equipments and troops, starting the fourth Indochina war.

During this time, Student-led riot in the Indonesia increases, which eventually lead to riots and heavy crackdown, which further fuel the flame. As the student demanded for the president to step down, the Indonesian armed forces attempted a coup in Jakarta. Subianto, the current president fled with his Loyal troops to Nusantara, Indonesia half-built new capital. This is the straw that break the camelback, which lead to the break down of Indonesia into multiple warlord state, and starting the Indonesian civil war.

Myanmar, seeing it's neighbor descended into major war, fuel each faction to increase their fight, in it's civil war.

In late 2025, Anwar Ibrahim, Malaysian Prime minister, was shot and kill at a rally. Which prompted the king to place Malaysia under a state of emergency, And for the king to dissolved the parliament and order a snap election.

With all of it's major member gone, It's headquarter in a war zone, on January 1st 2026, ASEAN is officially dissolved.

My mod is still on it's infant stage, with barely any progress because of school. But hopefully I can learn to be a better modder. But any help with the mod, no matter if you are coder, visual, gfx or writer, any help is welcome. Another thing, my mod draws heavily from TFR, so there will be a mix between realism and insanity. But other than that, feel free to ask anything, I will try to answer.

(Portrait picture will be in-game to comply with rule 8)

Teaser The capstone focuses and formable for democratic Iceland in my mod

Thumbnail

15 Upvotes

The capstone focuses and formable available to Iceland in my mod. Most of the focuses are about what type of government you'll get. You can have a bunch of types, even communist or fascist ones. But you also get access to a small foreign policy branch.

The foreign policy branch starts off by you determining if you'll be neutral or not. You can be historical and join NATO, or join any other available faction. And if that's not your speed, you can become neutral.

You then get focuses where you send demands to Denmark about its Atlantic territories. You can demand Faroe's independence, which is the same regardless of government type. However, the Greenland focus works a little differently. If you have a left-wing government, you will demand their independence. However, if you go any other government type, you will demand its annexation. This is to represent how the Icelandic communists were the only party that supported Greenlandic independence and opposed the Icepandic claim to Greenland.

Then you get a choice on what to do with your Atlantic neighbours. You can form an alliance with them, the West Nordic Council. Or you can united with them into the West Nordic Federation where you propose a unification of the three islands. Greenland is less likely to accept than Faroe for historical reasons.

And then you also get an option to buy Jan Mayen off of Norway.

Teaser Update on the HOI4 mod I've been working on!

Thumbnail
gallery
51 Upvotes

I've been working on this mod for a while now and here's an update since my last post!

The whole world map is now filled in and I've started working on some of the lore for the nations. I also finished the Nova Empire's flag and leader.

Lore:

In this timeline the Black Death was way worse than in our world, killing around 90% of Europe's population and around 95% of Asia and Africa. This caused many governments and empires to collapse and over time new nations started to form.

By 1936 technology has recovered to around the same level as our world but the politics are completely different.

One of the biggest empires to form was the Phoenix Imperium which was the largest empire in the world and had many colonies. But in 1890 the Phoenix Wars started when a coalition of nations teamed up to take down the empire. This eventually caused the Phoenix Imperium to collapse into many smaller nations.

Even by 1936 many of these nations were still struggling economically because of the wars. Because of this the Nova Empire managed to bring the former Phoenix nations together into a faction called the Phoenix Union.

Discussion [Mod Concept] Hearts of Iron IV: A Century of Alternate History (1910–2026)

1 Upvotes

Hello everyone!

I'm looking for feedback and potentially collaborators for an ambitious Hearts of Iron IV mod concept.

The idea is to create a century-spanning alternate history experience, with multiple starting dates:

- 1910: The age of empires and the road to the Great War.

- 1919: The aftermath of the First World War.

- 1920: Revolutions, reconstruction and political instability.

- 1936: The rise of new international blocs.

- 1939: A world approaching another major conflict.

- 1945: The beginning of a possible Cold War.

- 1950: A changing international order.

- 1991: The transition towards the modern world.

The long-term goal would be to allow players to continue their campaigns towards 2026, with evolving technology, national focus trees, political systems, diplomacy and alternative historical outcomes.

The initial inspiration comes from my own Great War Redux campaign, in which Germany won the First World War in 1915.

By 1922, Germany dominates much of continental Europe through the Reichspakt, Austria has reorganised into a multinational Habsburg monarchy, France is divided between a syndicalist Commune and a republican government in exile, Britain has established an Imperial Entente, and the Russian Republic has survived a Bolshevik uprising.

One possible 1936 scenario would feature four major factions: the Reichspakt, Imperial Entente, Danubian Federation and Third International.

This is currently a concept and planning-stage project, not a playable mod. I'm new to HOI4 modding and would like to learn while helping with historical research, worldbuilding, national focus design and project coordination.

I'm interested in meeting people experienced in scripting, focus trees, map editing, graphics, technology systems and balancing.

The intention is to develop the project in manageable stages, starting with a small playable prototype rather than attempting to build the entire century immediately.

I'd love to hear your thoughts, suggestions and whether anyone would be interested in helping develop the concept!

I'm playing as the Russian empire in The Great War mod but for some reason I can't produce new equipment. I've tried everything at first I thought it was because I was playing Russia so I switched to Germany real quick and I also couldn't produce new equipment. Also if I cancel the production line and try bringing it back nothing will show up. I even switched to version 1.19.0 but that didn't change a single thing. Any suggestions on how to fix this.

Discussion How do I get started making a vanilla expansion mod?

5 Upvotes

I'm very new to HOI4 in general, and I've never modded anything before. However, all I'm trying to do is add a couple expansion branches to a pre-existing national focus tree and change some country cosmetic tags. flags, etc (specifically for the battle for the Bosporus dlc Greece national focus tree). My end goal is just to give the Byzantine Empire more content. I feel it's quite lackluster, honestly, and I want to give you a choice to reform the Roman Empire as a whole as Greece, not just the eastern half. I also want to add in something similar to the Napoleonic France tree that lets you balkanize Germany if you conquer them, since a conflict with the Germans is natural for the reborn Roman Empire, and of course to be able to core all of the old territories of the Roman Empire at it's peak/move your capital to Rome if you want, since currently all you can core is Italy, the Levant, and the Balkans. I don't want to write a whole new tree, just add these new focuses as a branching path. Is there a visual tool that I can use to make these focuses, or do I need to write the code by hand?

I want to create a submod for Kaiserreich. I want to add an event where, if Germany has forced the surrender of all enemy nations in Europe and the United States is not at war with Germany, the Syndicalist British receive a 25% debuff to attack, defense, and recovery time which represents the collapse of morale.

I want to do this because the AI find it too difficult to launch a naval invasion against the British, and it's frustrating when they're the last enemy left and I have to finish the job.

2 Upvotes

I ask this because Germany is just too strong, to the point where, in the ten games where I didn't participate at the start of the war (leaving it as AI vs. AI), the Moscow Accord never manages to capture more than a few provinces before being pushed back and forced onto the defensive for the rest of the conflict. The Third International is even worse; even if Spain, Italy, Belgium, the Netherlands, and plenty of other countries join the war on the Third International's side, they never manage to take more than one or two provinces before being pushed back and forced onto the defensive for the rest of the conflict.
