It is possible to have your own weapon set on your server, but for that you'll have to create it. For that, browse to your GE:S folder on SourceMods (understeamapps) and look for a folder called scripts. Inside you'll find another folder named loadouts. In there you have to text files; the one you want is weapon_sets_custom.txt. Then it is just following the instructions inside the file. The pathway is
C:\Programs\Steam\steamapps\SourceMods\gesource\scripts\loadouts. Change anything on the adress when it applies. To choose your weapon set, you have to write its name (the one you gave it) on the appropriate field on the "Create server" option on the GE:S main menu.
Here's and example of a custom weapon set (how it looks in the file):
"km"
{
"print_name" "Killer Monkey's Favs"
"weapons"
{
"1" "DD44"
"2" "PP7_SILENCED"
"3" "KLOBB"
"4" "AR33"
"5" "RCP90"
"6" "GRENADES"
"7" "REMOTEMINE"
}
}
This set is already shipped with the mod and is called Killer Monkey's Favs, as you can see from tehe text above.About the weapon set and map cycle, I can't help you because I'm not knowledgeable enough on that to give you proper instructions; I don't make my own servers except for testing purposes.
Hope what I said helped in any way.
