BlackICE Historical Immersion Mod (Total Conversion/Immersion).End of a New Beginning (Total Conversion).Cold War Iron Curtain: A World Divided (Total Conversion).Trying to pick and choose the best mods through this vast white-out of choices can be as daunting as Operation Barbarossa (or learning the ropes of HoI4, which can be just as scary without the right tutorial).Īnd yes, there is a Battle Royale mod. With each of Hearts of Iron 4’s many DLC updates, the gargantuan family of mods has grown further, with players turning Paradox’s every new addition to their own creative ends. Naturally, there’s also a smorgasbord of mechanical tweaks and fiddles to choose from, adding new systems for AI, textures, music and more. On top of the base game’s famously deep and complex set of systems and interactions, its open-ended sandbox version of World War Two has proven extremely fertile ground for modders to create alternate histories, ultra-detailed scenarios covering later (or earlier) conflicts, and even transport you to other game worlds entirely. Still, let’s ride this tiger of selection, and focus on four salient categories to encircle some of the best mods out there. Of all the Paradox titles to deploy massive mods libraries, none might compare with the whopping collection of over 20,000 Hearts of Iron 4 Mods.
