Mod «Armed Forces Overhaul» for Hearts of Iron 4 (v1.10.3)


Armed Forces Overhaul is a ongoing project to completely overhaul the tech trees to become more challenging and historical. Right now it features a massive expansion to the tech trees, large improvements to the ai, and numerous small changes that improve the gameplay experience. The project itself is a branch off my total overhaul mod World Ablaze.

Each Nation has a customized tech tree and AI all with a unique flavor. (e.g. The tiger tank is what it always was, one of the most deadly tanks of WWII)

Also this mod closely follows historical statistics and dates but a few concessions have been made for the sake of balance. It also assumes the war can go up to 1948 therefore some post war techs have been included even those after 1948 to take into account the arms race that occurs during war.

Major Features:

  • A much more robust and dangerous AI (more so when going down historical paths)
  • unique artwork for all new technologies including vanilla ones
  • Expanded tech tree’s for all nations
  • Unique tech tree’s for each of the major nations and some minor’s
  • A complete rebalance of the game mechanics
  • more division icons with color
  • More research bonuses using Army XP
