You'll need to download the zombie survival gamemode from the workshop. Once that's done, change the gamemode to zombie survival when should be somewhere in the bottom right of the main menu. Rounds are done automatically and spawns and items are already in the map. Maps don't have many items since you'll mostly use the buy menu. The spawns are for multiplayer so they don't work with npcs.

I know all that but in like the source sdk. I mainly use source multi tool. Its like the best tool. I just dont understand. The gas clouds for z spawn, the zombie spawns. its just confusing lol.

Just look. ive released only 2 maps. but i have 1 map waiting in my folder to be finished.

If you want the map file, that i have in the folden then ask me... the map was first meant to be a zs map

You'll need the zombie survival fgd. The newest one is under noxiousnet's mapping section somewhere.

ok.
