Hi. I have to create a tutorial for that, but you can simply decompile a map to see how it's done.

E.g. zs_uglyfort is a nice one

There are specific entities you should use but in this version you can basically run any map on this gamemode and it will work fine but won't always be balanced lol.

But if you want to get technical the only entities you really need is info_player_human and info_player_zombie for setting up the team spawns.
You can also use info_player_undead as well it does the same thing as info_player_zombie.

Soo uhhh wrong mode, i meant to to make this post on a horde mode mod iv been playing on, iv never even really played zombie survival before sorry lol
