How Do I Make A Zombie Survival Map?

Hi it’s pretty simple really i want to make a zombie survival map the map it’s self is in the works already. But i would like a tutorial on what i would need to add the server i want it for is Left4Green which is a popular zombie survival server if anyone knows i would be very thankful.

Try asking on the Left 4 Green forums, or in Facepunch’s mapping section.

You can also check out the thread at noxious net.

Its not left4green,but its written by the guy who made zombie survival.

I want to thank u personally :smiley:
