I've tried to make the clients download the cs_dust.wad file but it wont work. If anyone of you got an idea of how to do (to make de_dust use it). Please send me a message.
If it is impossible. Then I want you to make maps for me.
It's nothing serious. The only important thing is that it should be funny to play.
There you got the .wad file - either you try to make it work on your server (if so, you have to rename it to cs_dust.wad) or you can try to make your own maps (name the map to ca_***YOUR*NAME***.bsp).
The choice is yours.
I would help you if I played/had 1.6. :-/
