My friend and I like to play dustbowl. We have for about 5 years now. We play on community servers so we can use are custom models and cross-hairs and textures. I myself have textured dustbowl into a nice green paradise. Now, some of the servers seem to be running a custom version of dustbowl. One server has couches all over the map. Another server has it to where you can build right in the re-spawn rooms. One server has increased the time to cap point number of 2 of each stage to 30 minuets. MY question is this. How are they able to edit a map like dustbowl and players join there server and not have to download a server specific version of dustbowl?
