Expanded Mods - Hearts of Iron IV
4 items

This mod does the following:
  • Pushes all technologies into the 1950s
  • Adds numerous new features and expands others
  • Adds Steel, Aluminum and Rubber production options
  • Creates some new tabs to hold all the fun


If two or more mods that change tech trees, the ui, or unit equipment come together, it will cause a portal to open unto the very depths of hell. This may adversely effect your game’s performance, and start the apocalypse.

In all seriousness, this is a big mod. It changed a lot of files and there’s no way around that. Trust me, I’ve tried. So with that in mind, please know that if you use other mods aside from the ones I’ve made – I cannot guarantee that things will work.

Also! Road to 56 includes this, so if you have that you do not need to have any of the Expanded mods.

Included Mods
  • Armored Cars by Admiral Caon
  • Escort and Light Carriers by Pinback
  • Equipment Conversion Enhanced by CrouchingLemur
  • Improved Equipment by Jamryl [I.D.S]
  • Jaeger Units by Herman Lindqvist
  • More Variants for R56 by Vydazy and 3ntf4k3d
  • Realistic Air Missions by Aerodil
  • The War at Sea


You’re messing with me, right?

If you like this mod, you might also enjoy one of the other things I made. Go ahead and check the collection if you’re feeling dangerous.

Thanks a lot for your permission. We've provided a link back, and are working to translate it now.

Yeah, of course. Please give full credit and provide a link back to my mod - and good luck! If you have quests contact me on Discord and I'll be happy to help.

Currently I am engaged in totally rescripting the entirely technology tree from scratch for Road to 56 - and this is likely to take some months. I appreciate your patience with the lack of updates, but please know that this will be a total overhaul of the mod as well as the basic vanilla systems too. Please look forward to it. :)

Hello, I am one of the authors of Touhou World War mod. Could you please permit our mod to use this mod and translate it into Chinese?

Hi, I'm the creator of the Alternative History MOD.

Can I use some of your created MOD?

Of course, this will be reflected in the credit.
