Question about instagib (railgun type weapon only)

Hey!
I started playing warsow 2 days ago with friends, we realy enjoy this game but we would like to create our own server and train with each other, and here is the question.
Our favorite "game type" i dont exactly know how to call it is: Instagib, with only this "purple looking" railgun, server that runs this mod is for example "Instagib, wda4, all day, all night!". I read on forum that You need to download modified dm config to setup server like this but i cant find it. Is there any chance that some of You guys could help me to do it?
Thanks in advance, and sorry for my English.

There's a setting when you host a game that says instagib; you just set it to true and it makes the instagun the only weapon in whatever gametype you've chosen.

Alternatively, in a match you may be able to callvote it or set the console variable for it; cvarlist lists all the available variables.

g_instagib 1 in the server config is all you need.
