What are the best Hearts of Iron 4 mods? Which of the 28,000+ available HoI4 mods should you choose when looking to spice up your time in World War II?
Just like Paradox's WWII grand strategy game continues to receive content five years after launch, the collection of existing Hearts of Iron 4 mods also grows, offering players a plethora of potential choices which can be a bit daunting to go through.
Our list of the best HoI4 mods aims to highlight a small portion of player-made modifications that are particularly worth giving a shot if you're looking to enhance or completely overhaul your Hearts of Iron 4 experience.
The Best HoI4 Mods
Installing the best Hearts of Iron IV mods is made particularly easy due to the available Steam Workshop integration that lets you add most mods to your game by simply subscribing to them.
Coupled with the Paradox launcher that lets you easily search your mod collection, you can easily find mods you want to turn on or off before heading into a game.
Our list of the best HoI4 mods starts off with a handful of total conversion and alternate history mods but will grow in the future with other picks, as well.
One of the most popular Hearts of Iron IV mods out there, Kaisereich proposes an alternate history in which Germany won World War I. As expected, given the circumstance, the mod reworks the world map by adding new states and provinces, while also overhauling the game's political system which now includes party popularity and ministers. Players will have over 100 Focus trees to explore when playing as different nations alongside new 3D models to further enforce the feeling of alternate history. Subscribe to it on Steam Workshop.
Old World Blues
Old World Blues is a total overhaul mod that brings the Fallout universe into HoI4. Featuring a custom-made map of North America that includes 11300 provinces, 866 states and 146 nations, the mod also comes with a dynamic war system that makes the different active factions capable of exploiting an opponent's weakness and striking at the right time. Detailed 3D models for robots, power armor and unique infantry models for factions like the NCR, Legion, or Vault City, alongside impassable mountain ranges and navigable rivers, ensure immersion as you take the helm of more or less known factions from the Fallout universe. You can travel to the year 2275 by grabbing the mod from the Steam Workshop.
Hearts of Iron IV's Expert AI mod is aimed at those players who're no longer challenged by the game's vanilla AI. Acting as a (mostly) complete AI overhaul, the mod significantly raises its efficiency when dealing with division designs, division production, diplomacy, naval invasions and more while also adding new features including a scripted AI focus system that lets computer-controlled opponents select the strategies that best suit their situation from a pool of over 400 options. In addition, players will be able to customize more elements pertaining to difficulty alongside the AI's behavior and military focuses. If you're up for an extra challenge, grab the mod from Steam Workshop.
The Road to 56
One for alternative history enthusiasts looking to play past the end of World War II, The Road to 56 lets you take your nation all the way to 1956 (surprise, surprise) while adding new Focuses for names that include Argentina, Armenia, Croatia, Cuba, Honduras, Sweden and more. If you choose to dip in, you'll also find an expanded tech tree alongside new units, laws, releasable nations, and other new additions. Find it on Steam Workshop.
The Great War
As its name suggests, The Great War is a mod that moves Hearts of Iron IV's action back a few decades to when World War I began. Featuring three starting scenarios in 1910, 1914 and 1919 respectively, the mod lets you control both the European powers at the center of the conflict but also take part in events like the Mexican or Xinhai Revolution. The mod has been built to follow the dynamics of The Great War in terms of technology, infantry being the dominant force before airplanes and tanks begin appearing on the battlefields. You'll have access to several reworked National Focus Trees, trench systems, gas and more than 500 technologies. That being said, there's plenty of potential to create alternative scenarios as you're not forced to retrace the actual course of the war step by step. Subscribe to it on Steam Workshop.
Millennium Dawn: Modern Day Mod
A collection of mods rather than a single one, Millennium Dawn's most obvious change is that of bringing the modern-day world map into Hearts of Iron IV. Naturally, its set of changes go much deeper than the surface, also introducing new economic and political systems alongside new technologies and focus trees that better suit the modern world. Players will have to deal with national taxation, debt and internal political factions, while new 3D models better reflect the change in period. Grab it from Steam Workshop.
Endsieg: Ultimate Victory
The Endsieg: Ultimate Victory mod adds five scenarios to HoI4 starting with World War I, continuing with 1941's Operation Barbarossa and ending in 1945 with the scenario that gives the mod its title, seeing Germany on the brink of defeat. Aside from a reworked AI, the mod also adds Rations and Fuel as resources to increase the level of realism. Find it on Steam Workshop.
Paradox grand strategy games are notorious for their overwhelming UIs that require a serious amount of patience to fully understand. The Coloured Buttons mod, although small, is an extremely helpful addition to your collection that adds color to several important buttons, not only making the UI easier to read but also resulting in quicker reaction times thanks to the color-coding. On top of that, the mod simply makes the UI look a bit more alive. Grab it from Steam Workshop.
BlackICE Historical Immersion Mod
BlackICE Historical Immersion is a HoI4 mod for those seeking a greater challenge combined with added historical accuracy. It adds multiple new units and equipment types, including country-specific armor, aircraft and ships for the game's major nations. Laws and politics have also received some love, being expanded to offer players greater levels of freedom in terms of how they govern their nation, while factories can be specialized to lower production costs. Subscribe to it on Steam Workshop.
Total War is a Hearts of Iron IV mod that provides its own different take on a more challenging and historical approach to gameplay. It makes building different types of equipment more expensive and, subsequently, more important to the player. Managing your economy and building proper relationships is also much more vital, while multiple AI improvements, the addition of combined arms logic and hundreds of new events, leaders and focuses further add to the reasons why it's worth giving it a try. Grab it from Steam Workshop.
