How do I made Zombie Survival maps?

I just wanna know:
-What the zombie and human spawns are called
-Any special things
-Ideas are fine too

So if you’ve made a ZS map or are making one, It’d be great if you helped me. Thanks!

Check out this thread:

ZS uses custom entities, and you can load them all into Hammer by extracting this FGD file that someone made into your (don’t quote me on this) sourcesdk/bin/ep1 or orangebox/bin folder. There should be several FGD’s there already.

TYVM! that was fast!

Do I do anything for Zombie Escape?

I thought I was very terrible at English but should it not be" How do I make a zombie survival ma?".
