It's pretty simple to upload maps to the Garry's Mod workshop. You can follow this Wiki guide from the link at the bottom of this comment for step by step instructions. The only thing that's required is the BSP file of the map. You can find those in your GMod map folder located at "\GarrysMod\garrysmod\maps" if you've downloaded it from a server or the workshop. Otherwise jump right into the wiki! Just remember if the map is already on the workshop, you probably shouldn't upload it. This was my case with zs_ravenholm.

If you have anymore questions, fill free to ask.

I know this server where they used the Bioball infection where players who got turned can control a large horde of zombine npcs. No worries I try the older map :) BUTT is there any way I can re upload a very good zombie survival map? Thank you.

I'm sorry, but there aren't any AI nodes on this map. They're pointless for the Zombie Survival Gamemode so I didn't keep them in. Although the original version I uploaded does have the Ground Nodes and some NPC spawners. You could try that version. As for Zombines, that's a no. :(

If you would like Zombines, you would need to join a Zombie Survival server that has Zombines as a playable zombie. Although if you want to screw around with the Zombine NPC on Sandbox, you would have to use the original version of this map and then manually spawn them in.

Sorry about that! If you have anymore questions please ask!

is this optimised for AI nodes are there zombines?

No thank you for the feedback!

Great ! thank you so much ! :D

Mhm of course! I might need to rebuild the lighting from scratch but that's easy. :)

Oh that's nice :D Also, is it possible to make it a little bit darker inside that big house? That would be awesome :p

That's awesome! Soon I'll be pushing an update fixing the lighting and maybe even making the rain look prettier. :)

Me and my friend playing zombies on zs_deadblock_v6_fix :D https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=680944371 Much fun, much awesomeness, such good fixed map :p

No problem and thank you for trying out the map!

Pretty cool zombie map. Thank you for fixing those problems ;)
