Mod «Novum Vexillum» for Hearts of Iron 4 (v1.16.1 - 1.16.5)
Last update: 13.05.25.
Reason: Update mod to version: 07.05.25
This project aims to be a modern era total conversion, starting where Millennium Dawn Classic left off. This mod will initially contain nearly all existing features in MDC, as well as several new features and many graphical improvements. Over time, this will diverge until the point in which all original features from MDC are replaced or overhauled. While we will be adding complex features, such as advanced economy and political systems, many of the significant gameplay changes are planned to be optional or low-impact. We understand many players of modern era mods prefer a military sandbox experience over geopolitical adventures, and we want to cater to both demographics, where possible.
Current Features:
- Starting decisions for customizable gameplay;
- Fully integrated and extended MTG naval tech tree;
- Streamlined tech trees, including new carrier variants for fighters, attackers, and naval bombers;
- Significant graphical enhancements and better tech icons;
- About a dozen new decisions, with many more to come;
- Newly balanced land units and vehicles;
- Completely integrated fuel system;
- New industry tech tree.
Plans:
We have many planned and in-progress features on the way, as we expect the development time of this mod to be many months or years. Our end goal is to create an interesting and accurate depiction of modern geopolitics, international trade, social cohesion and unrest, and warfare. The plans which follow are not necessarily all that will be added, as there are too many to list here.
- New focus trees to replace all existent ones;
- Abstract economy and political systems;
- Advanced internal politics;
- Social cohesion and unrest;
- National personalities, adding new possibilities for international conflict;
- International trade and political agreements;
- Realistic naval combat and configurations;
- Extensively accurate vehicle and equipment icons and names;
- Helicopters;
- Interactive space program;
- New 3D models for all in game units.

Could you make a National Foucus in Czech and Slowak Focus Tree to Reunite Czechoslowakia Please.
Thanks !
The Mod Creator/Team are clearly focusing on the naval aspects of this mod which is fantastic but please do not go in to the direction of millennium dawn. It has a lot of stuff but it comes off as shallow. Please add a theocratic Ideology and a fundamentalist/Extremist religious ideology as opposed to Islamist.
bro, millenium dawm just turned into shit, game lags if you dont have a nasa pc, lot of complexe and unnecessary stuff, its impossible to undestand how all things work, unplayabe
nice mod lol
can you but a real generals in palestine with thier photos
Finally Pakistan is Nuclear!!!!
can you update this mod to accomodate 1.10.8 version?
The mode is good, but the icons are a bit problematic, I hope it will be fixed in the future
They updated the mod today, can you guys update it here too ?
update

Is this mod updated to the latest version of hoi4?
My grandfather used to be لواء ركن in english it meant lieutenant general in the iraqi army (before 2003)
His name is Sadoon Hashim Al Maliky
Update please
Guys can someone help? I use various mods and they all work, but when I try to use total overhauls mod (such as Novum Vex) i always get the map definition error? What can I do?
Guys, I only have one thing to ask, don't turn this into a millennium, don't follow that millennium dawn path. That mod is over. That mod has a lot of useless things that are very hard to understand. And besides, that mod crashes a lot if you don't have a NASA PC, it's impossible to play. But this mod came to change that. I'm already finding it much better, precisely because of the lack of complexity. It's basically the hoi 4 vanilla, but with a modern times mod, it's very good like this, just keep updating the game with focus tree and updates in the countries that will be successful. Hugs from Brazil!

Hello,
It crashes, has missing lines, for example, «common/decisions/POL.txt:208: UCO: Invalid Scope, supported: State|Country|Character|Combatant|Ace|StrategicRegion|Operation|Unit|Military Industrial Organisation|Purchase Contract|Raid Instance|Special Project, provided: None»
or
common/units/equipment/tank_chassis.txt:342: has_idea: BUL_army_restrictions is not A valid Idea
etc.
I fixed one, then others appear… some files are corrupted i assume, that trigger crashes in some events. I tryed the game without dlcs and still crashed.
