Find the custom map you want. (Note: Some maps no longer work)
For Example, I found this.....
https://steamcommunity.com/sharedfiles/filedetails/?id=252196727
See how the url ends with the numbers 252196727
Edit the file on your server
\AAPG\AAGame\Config\ClanHost\DefaultSteamUGCManager.ini
ADD
ServerSubscribedItems=(IdString=252196727)
AFTER
[SteamUGCManager.SteamUGCManager]
SAVE AND CLOSE THE FILE.... Reboot your server the server will download the maps
Now click "Edit Commandline" and add the below into CUSTPARAM1
FLO_UrbanAssault$76561198010782041_th
To get this map name I went to.....
\AAPG\Binaries\Win32\steamapps\workshop\content\203290\252196727\FLO_UrbanAssault$76561198010782041_th.umap
