I've seen people have zombie counters in zombie games and I would like one. I have been unable locate any mods or scripts that work for me. (I've been searching on and off for a day and a half)

How exactly do I add them? I don't have a single .gsc file in any of my folders for the game.

I have seen this link:
http://www.zombiemodding.com/index.php?topic=976.0

This link does not help me. I think I may also be missing other UI things like parts lists and objectives etc.

I need help. I'm so stressed. I've been trying to find this solution for the longest now and have yet to succeed.

I also am having this problem

You definitly made something wrong when you search one and a half day for a zombie counter tutorial.
Just type "cod waw zombie counter tutorial" into Google and you'll find many sites.
Anyway, here's a very easy zombie counter

You're trying to add a zombie counter to the base game, right? If you don't have the mod tools installed, that would be why you have no .GSC files.
