Mod «Special Research Division» for Hearts of Iron 4 (v1.10.3)


Hi everyone and welcome to the Special Research Division, SRD for short. Here you will find all the Technologies, Equipments and Buildings that Normal people would call NOT FITTING IN A WW 2 GAME.

His Mod will explore 4 different types of strange technologies:

  • Cyber/Sci-fi with Mechas, Cybernetics, Drones/Robots
  • Holy/Theology with Angels, Knights, Mages and Church Tanks
  • Bio/Hell with Zombies, Bio Weapons and Hell Spawn mixed with Machines
  • Wunder Weapons with Crazy Building, Tanks, Guns, Airplanes.

A big Emphasis will be placed on balance and compatibility with other mods (See: Balance, Compatibility).

This mod wasnt build to be a power trip. All stats for units/equipment are near vanilla Stats. With this mod you still wont be able to conquer the world with Albania before 1945 (Trust me, I tried). But playing majors/major minors will be a bit easier.

There is a Difficulty event build in if someone wants to feel an artificial challange even with the new units.
