Mod «Doomsday series: Zombies» for Hearts of Iron 4 (v1.10.1)


I know there are a few zombie mods out there, so what makes this one so special? This mod has everything one could want from a zombie scenario.

First let’s begin with the zombies:

The horde is made with realism in mind. These zombies won’t use planes, tanks or ships. Instead of landing somewhere via ships, I’ve added a lot of events to simulate this behavior with unique decisions to go with it. Instead of gaining manpower instantly, they consume state population. So after a while many states won’t have any population left. The Zombies are also unable to build buildings. Last but not least, nations consider Zombies a global threat and won’t send them any volunteers or anything. The zombies will also delete any equipment they get from capitulated nations. They also have unique 3d models and sounds.

As zombies don’t have a government of some sorts they don’t have a focus tree. This is also to prevent them from improving relations.

The next big feature is ZCOM:

It is a nation focused on defeating the zombies. ZCOM comes with a unique focus tree with about 90 focuses. ZCOM has a very unique playstyle: It needs other nations to produce men/weapons, but it buffs every nation fighting the zombies. Here are a few key features for ZCOM:

  • A completely unique focus tree with about 90 focuses and 3 different Paths: Help, Dominance and Colonial defense.
  • Over 40 Events only dedicated to ZCOM
  • 14 decisions
  • A scripted gui for special weapons
  • 15 unique ideas (with icons)
  • Unique Portraits


The next part that is very unique for a zombie mod are flavor events and decisions for nations around the world. There are about 30 flavor events for various nations including Germany, Italy, India and Great Britain to name a few. Some even have a pretty big impact on the world around them.

The fourth big part of this mod are different rules:

There are for different types of rules:

  • A completely new spawning system with three options:
    • The normal spawn point in India
    • A (somewhat) random state in the old world
    • An Infection spawn as a Tribute to the now dead Infection mod.
  • The possibility of changing the strength of the zombies at the beginning of the game from normal, hard, extreme and insane.
  • The Path ZCOM should take for their focus tree.
  • The possibility to deactivate the global alliance. Now you can choose between a global alliance and the normal alliances.

Another big part of this mod is that it is compatible with any other mod on the workshop. I know, crazy. Please notice: Compatible doesn’t mean balanced or anything else. It just means this mod can be loaded with any other mod on the workshop. All mods except Kaiserreich worked without any problems.
