Hey everyone! This is just a short guide on how to use modded maps in Project Zomboid for both solo and locally hosted multiplayer.

Since this guide was built specifically for my collection of compatible map mods, I'm going to say there. However, you can find plenty of map mods on the steam workshop.

1. Subscribe to either the entire collection of map mods, or pick and choose which maps you would like to play with. Great thing about this collection is that all of the maps are entirely compatible and don't overlap each other (excluding a few connecting roads, hence the load order). Be mindful of any individual dependencies each map has, they are all included within the collection.

It's recommended to use Mod Manager: Load from Collection for this step.

1. Go into mods, enable all of the map mods and their dependencies.
   
2. Where there is more than one mod available, select the following mods:
   
   • Bunker: Last Minute Prepper Reloaded
     
   • ExtraNoise's Flag Tiles
     
   • ExtraNoise's Flags Tiles: Craftable (optional)
     
   • Muldraugh Checkpoint Safehouse
     
   • Research Facility, KY
     
   • Research Facility, KY (Access Road)
     
   • Shelter 22 28 - Spawnpoint Enable
     
   • Shelter 41 25 - Spawnpoint Enable
     
   • Shelter 49 12 - Spawnpoint Enable
     
   • Shelter 22 38 - Spawnpoint Enable
     
   • MK Hospital Area_Normal
     
   • Uncle Red's Bunker Redux
3. Click Load Order and move the following maps to the top of the list in the following order:
   
   1. Fort Knox linked to Eerie Country
      
   2. Road between Fort Knox and Bedford Falls
      
   3. Road to Bedford
      
   4. Bedford Falls
      
   5. New Albany
      
   6. Jasperville to Louisville Wilderness
4. Click Accept, wait for the LUA to reload and start a new game.

Skip any steps outlined for solo above.

1. Select Host and create a new server by going to Manage Settings > Create New Settings. Give your server a name, click next, save and then quit Project Zomboid.
   
2. Open your file explorer and navigate to C:\Users\User\Zomboid\Server (be mindful your username may vary). You should see a list of files that look like this:
   
   
   
   
3. Right click the .ini file (your server config file) and open in Notepad or another text editor.
   
4. Open the Cells and Multiplayer Data[docs.google.com] file linked in the description of the collection. Go to the Multiplayer Data tab and copy and paste the following:
   
   • Mod ID into Mods=
     
   • Map Folder into Maps=
     
   • Workshop ID into WorkshopItems=
5. If you are subscribed to the entire collection, or are using a map dependent on Aquatsar Yacht Club, you will need to disable anti-cheat type 12. Navigate to the line "AntiCheatProtectionType12=" and replace true with false.
   
6. Save file and close.
   
7. Right click the spawnregions.lua file and open in Notepad or another text editor. From Pastebin[pastebin.com], copy and paste the entire contents underneath:
   
   { name = "West Point, KY", file = "media/maps/West Point, KY/spawnpoints.lua" },
   
   and before
   
   }
   end
   
   Save the file and close.
   
8. Load back into Project Zomboid. Go to Host, select your server and start. I recommend a minimum memory of 6GB for 2 players. Add an additional 500MB per additional player. If you are running other mods, assign more memory again.

Note: multiplayer can take a very long time to load and the game may appear unresponsive while it is initializing. Be patient and give it time, it can be upwards of 10 minutes.

If you are having issues with multiplayer, try the following:

• Check you have followed the guide completely, put all of the data in the right places and set AntiCheat Type 12 to false.
  
• Give the server enough time to initialize and don't quit if it's unresponsive (unless it's an excessive amount of time).
  
• Check you have allocated enough memory for the maps, number of players and an extra mods you are running.
  
• If you're playing with other mods, try creating a new server with just the map mods.
  
• Start a new server, don't modify an existing server.
  
• Try starting a server without any maps or mods.

If you continue to have issues, try reaching out on Discord[discord.gg]. I'm no expert on multiplayer and can only help so much, but the community is very helpful.
