How do you change zombie damage?

[GateDiggers]

I have this mod for BO1 (I forgot where I got it from) but I want to port it to BO2. I want zombies to do 25 damage that way it takes 4 hits to kill (8 with juggernog). Increasing the max health causes juggernog to reset the health back to default, instead of boosting it.

#include common_scripts\utility; 

init(){ thread infected_dmg(); }

infected_dmg()
{
	while(1)
	{
		infected = GetAiArray( "axis" );
		
		for( i=0;i<infected.size;i++ )
		{
			if( is_true( infected[i].meleeDamage ) )
			{
				infected[i].meleeDamage = 25; //This value is amount each infected will inflict damage to a player
			}
		}
		wait 0.05;
	}
}
