Oh i like this already, one of my grudges is that creature hunts are quite boring beyond like year 1, because it boils down to Napoleon war style firing lines of soldiers, against enemies that are stumbling randomly while they are getting picked off one by one. I like how zombies were changed to charge you, not only it makes missions shorter (Which is probably the biggest factor, too many enemies that often are hiding somewhere, but its too risky to go and explore given most creatures can destroy your agents in melee, even with decent armor so its back to firing lines), it also is the perfect scenario for short ranged weapons. When its zombie slaying time, i just give every single soldier a shotgun, because everything will be at shotgun range eventually.
I know i will regret activating this mod at some point, probably will have it innactivate for early game and activate it mid game onward.
