Just got the game..some issues

[Emp]

I got to agree here with my fellow ghouls.
Cycle the zombie cards and check the rulebook again. Like Mqstout said, you might have misinterpreted the fighting rules.

Helping to remind the hero players that when the hero card pile is empty that it's game over for them also helps
It put's of those lazy campers who keep searching and searching

And camping...well...in my experience there is only one scenario that has an advantage by doing that and that is the Die Zombie Die one. All the others will have the hero's running around. They have to or they will nog find anything or reach their objectives.
Ignore the campers, that is what I do and I play zombies 99% of all the games we do.

Good luck and don't give up!
