Mod «Millennium Dawn: Optimization Submod» for Hearts of Iron 4 (v1.11.9)

Millennium Dawn: Optimization Submod

This is only the optimization parts of my Multiplayer Overhaul mod for Millennium Dawn without the balance changes. You do not need this if you are using the Multiplayer Overhaul as it is already included. This aims to drastically speed up the game by removing and merging minor low-game impact nations.


  • Merges many less important nations into a colorless state and removes all their buildings.
  • Merges many other less important nations into larger surrounding nations.
  • Fixes
