PC Modifying difficulty parameters

[DominionZA]

Is there a way to modifiy the difficulty parameter so that I can have all the effects of it without zombies' HP increasing to become bullet sponges? I'd like to play on insane but without having to fight for atleast two minutes to bring down a single zombie. I'd like a faster raise in gamestage I believe it was part of it

The difficulty no longer has any influence on the gamestage. To quickly rise the gamestage you would have to change the XP multiplier in the settings.

The rest would have to be done with modlets that increase the damage from zombies without reducing the damage from the player.
