First, you need to download the right version of dedicated server ( it's not the one that comes with soldat) from here :
http://www.soldat.pl/down-s.htmlThen you will notice a 'scripts' folder, thats were you unzip the scripts to, (if the script isnt in a zip file, ask the aker to put it in one).
To change gamemode etc. edit the soldat.ini file, after a while, you will understand how to use it, if not just ask us what you r problem is.
To play it, you have to double-click on soldat server
before you start soldat, then start soldat>join game, change it at the bottom to LAN and request, your server (if not changed) will come up as 'soldat dedicated server' ,and will be the only one, join it.
To add bots ingame, type /addbot <bot name> (make sure you get the capitilization right)
e.g /addbot Kruger
To add to alpha, use /addbot1
to add to bravo, use /addbot2, and so on
You can use /gamemode <#> to change gamemode in-game
Ask for any other commands.
Hope that helped, have fun!
