[blckeagls' Real Zombies v0.0.5]

1st Posting here - managed to get the script running like a charm, but the zoms seem to be very easy to put down.

The section of code below increases the number of Zoms, but how do I make them harder to kill - increase HP - Hit Points 

Thanks in advance.....

while {_num < 5} do {
                        _coords = [_pos,5,150,5,0,50,0] call BIS_fnc_findSafePos;
                        _num = _num + 1;
