It may be beginner but im still proud.
i have 1 problem. When you send for help what does it do because i did it when i had no ammo.
It seemed to spawn a glitchy richtofen that hit me.
I didnt have enough points for ammo.

The game keeps crashing on the loading screen. Please help.

thanks it works now 

i do not have a mods folder or appdata i have it working with out a mod folder

Edit: i have appdata but there is nothing to do with steam on it

Zombies wont spawn it just says intermission 

Quick revive is in the floor

Where is the buyable ending?

I am having a error while loading the map. It goes through to the activision intro then the screen goes blank with a loading bar but its frozen then you can hear in-game sounds. I cant play this is also happened with me a few times.
