DarkRP Zombie Survival?

Alright guys idk if i posted this in the right section but it is about a gamemode, and its just a question. What/Where can I find that one Zombie Survival RP gamemode that had the F4 Menu like DarkRP?? I looked all over garrysmod.org and its not there -.- So dont flame/troll this thread just give me a simple answer. All answers would be appreciated, thank you.

Make your own DarkRP edit, it’s not hard.

I believe it’s just a map.
